- Quick build and ride (45MPH!) of this 3000W carbon frame custom ebike build!
This was my 5th ebike build and I ran into a few issues while installing as at the time I lacked the experience, but that's why I do this!
I've gotten some flack for using frames and bikes from Walmart, criticisms such as the frame will be cheaply made and fall apart, or can't handle the power of electrification, but I completely disagree. I've done enough of these builds now to know the truth and you can have a quality bike that goes very fast for not a ton of cash. You don't need a frame made of beryllium and ceramic brakes to have fun or even a nice bike.
I'll detail all the steps I took to convert this regular downhill MTB carbon frame to a very fast electric bike. It may not exactly be a how-to but it should give you enough of an idea on how to make your own!
The most troublesome part of any hub motor build is affixing the rear hub, especially if it's a frame you're not familiar with, getting all your washers and spacers and having more components you need to line up (like disc brakes) can add to the challenge. As long as you can tighten everything down and it still turns smoothly, then you're golden.
This is a 2000W base kit with the upgraded controller (50A) which pushes it to 3000W+ (it's more like 3500W) other upgrades are the very nice full color IPS display for odometer, speedometer, and more. This package is my favorite for 72V systems, pieced together with a very large 20Ah triangle battery with a super convenient velcro bag allows for easy installation and fits a wire array of frames.
Much more e-bike builds and more coming up on the channel, stay tuned!

\\ 3000W Carbon E-bike V5.0 \\
After huge success with my BMX build, I decided to try this drive train out on a larger frame (26") I figured it would be just as fast, maybe even more and I wasn't disappointed.
1. The Frame
Walmart "Hyper" brand 26" downhill mountain bike. This is a relatively cheap carbon bike (I believe it was $600 new) it made for a great electric bike platform and I was happy to know that it could handle all of this power.
2. The Battery
72V (84V really fully charged) 20Ah triangle pack
3. The Controller
Custom 50A with UKC1 IPS display
4. The Motor
2000W "base" kit, but can push much more power (currently handling 3500W+)

Honestly your projects are really bad ass and the finish you put really shines.
Thanks so much man, much appreciated!!
Loving these. Your dedication to showing the "real" troubleshooting process, along with the practicality of the bikes you're building are amazing and informative.
Thanks so much!! I appreciate it ⚡
Awesome build dude.
Great video as always!
Thanks for watching man! 🙌
Oh man!!! Too funny. I built an e bike for myself and also am building one for my girlfriend right now and am having the exact same experience as you. Brake rotor rubs, put the tires on the wrong way, spacing is too tight but don't wanna crack an aluminum frame...
I sacrificed my lowest gear being smooth on my aluminum frame just so I didn't have to add anymore spacers.
Super fun when it's done... the trial and error part tho... a man needs major patients.
Keep up the great work!
Oh yeah I've been there many times with these builds, to me giving up 1 gear is totally worth it, most of the time I just go in higher gear and only pedal when I feel like it. I'm sure your gf will be glad you made her one! Once you have an ebike it's really hard to go back to a regular bike 🙌
@@hightech-lowlife considering making diy kits?
Really nice ebike build and great video!
Thanks so much!!
👍 Great build.🤩
I also added a drop-down converter 12v system to my bike , which supplies lights,horn,turn signal and alarm.
That was Fun to work out ....IE : running lights with turn signals that work as signal when lights are off .
My next project has WiFi stereo system and solar charging.
That's awesome man! Yes, I think buck converter is the way to go when running accessories on an ebike. I will be making a tutorial on how to do it because a lot of people are still just using separate batteries, which is fine, but why not make it cleaner?
Solar would be pretty cool if you have the frame real estate, and always nice to add some tunes 🍻
i like it very much! man hub motor look so good & so much easier, think i need an upgrade soon :)
Thanks man! You will love a hub motor, trust me - so much power and so quiet!!
Upgrade? It's already in motorcycle territory
I love your builds... thanks for the vids...
Thanks for watching man, much appreciated!
You have a lot of faith in that Carbon frame. With 3000w and all the 72v battery it's going to be a rocketship, but i wouldn't want to go too fast, especially over rough roads.
45 is pretty fast, wouldn't want to go much faster on a regular bike frame 👍
Wow nice job, looks really good.
Thanks so much!
Hi High Tech,
Great fan of you and your channel. I have so many comments and questions but will spare you mostly :-) To me, you precisely capture the hobby as a very creative man. Only a man with your creativity would stop and take a breather from your most complex of all ebike builds to build this bike. Love it. This type of build is more up my alley because its simplier. :-)
First my comments and then my question please...
My comment is, for those soldering XT60 connectors on their batteries and controllers which is my connector of choice as well for less than 60 amp builds and I only build lower power bikes because I prefer gas motorcycles for faster transport on the road...a tip is....tin the tip of the heavy gage wire, then tin the connector channel..fill it with a small puddle of solder...place the connector with back part of the connector attached for a heat sink in a small soft chuck vise, apply pressure and let the tinned solder melt together. This creates a perfect connection. You can find this procedure on youtube for those interested because these connections almost have to be made on ebike builds.
Second comment is and completely agree, rear dropout spacing is always the biggest challenge on rear hub motor builds. Best way in my experience High Tech is...always remove the chain and rear derailleur when fighting with the spacing. Makes it much easier.
And lastly, my question please because I deliberately avoid carbon fiber frame builds because I generally prefer mid drive ebikes and carbon fiber bottom brackets don't have the compression strength of Al, Ti or Steel...they crack when applying 50 N-m of BB nut torque for mid drive retention.
So my question is....can you describe the spacers you used on the left and right side of your build to properly align the rear brake rotor to the caliper and to offset the rear cassette from the right side drop out so it would clear adequately?
How much did you have to stretch the carbon dropout which starts at say 135mm spacing?? to create the proper clearance to get it work in back?
Carbon as you likely know in material scientce has a much more abbreviated stress/strain curve compared to Aluminum, Ti or steel which can be bent aka permanently set to a desired rear spacing dimension. Can't do that with carbon fiber, it will crack. What you can do however is 'spring the carbon dropout' to the desired dimension. This makes tire changes more problematic of course because the rear triangle is always under a level of preload. My question is...how much did you have to spring the rear dropout to get it to fit with the right spacing?
Thank you very much and for sharing your talent with us.
Thanks Luke, must appreciated! I never watched a tutorial on the 'right' way to solder up an XT60, but I may have a go, sometimes it's hit or miss with getting it a full solid connection, but I've never had an issue with soldering them, but thank you for the tips 👍
Yes, the more components you remove (caliper, derailleur, etc) the easier it will be to put on the rear hub for sure.
I'm not sure how much I had to stretch it, not much, maybe 4-6mm total? It still had 'some' give to it but not a lot, I was afraid of it potentially snapping, but this stuff is incredibly strong, I don't think I could have broken it with my bare hands.
Even though the carbon is cool, I prefer steel frames for ebikes as I usually throw a ton of power on them and strength is more important to me than weight. Thanks for watching and your thoughts, I appreciate it!
@@hightech-lowlife Thanks for your response about the carbon frame stretch. I own carbon bikes but never tried to mount a rear hub drive on one and was curious about the spacing and stretch.
On the soldering front, I personally struggled with soldering XT60 connectors so went out on youtube to find the preferred method because I figured it was doable and I just wasn't using the right technique. My original thought was the trough could be pinched to hold the braided wire when soldering which was wrong. I learned adding solder was a bad idea, the key is to pre tin each side and then join with pressure and heat.
This creates a really sound solder joint.
Love your builds and your talent and thanks for sharing it with the ebike community.
@@lukewalker1051 No problem! Yes I was weary to stretch it but it worked out just fine. The XT60s are hit and miss for me, sometimes I can lay them down perfectly, other times it's a disaster, I just keep going until it's ok 👍
Thanks for following along Luke and for all the kind words 🙌
Don't need a carbon frame for an ebike. Some on here say aluminium, but thats not great either. Best, safest frame material is chromolly. Strong and bends long before it brraks catastrophically. Plus the frames are dirt cheap. Something like an old Kona Lavadome frame in Tange Chromolly is perfect for a hardtail conversion. Having said that, I only build full suspension bikes now. Once you've felt how much safer a full travel suspension bike with decent forks and good brakes feels at 40 mph, there is no going back!
Yes, it's true. I think steel is the best material for ebikes, especially with a lot of power. Suspension bikes are the best, I will have 5+ full suspension builds coming up on the channel. They're more challenging because there are less convenient places to put batteries, but with some thinking it can be done without too much stress. 🍻
I have a full suspension (rockshox forks and shock, giant anthem with a 52v battery and a 1500w wheel. I’ve had 42mph out of it. It handles the road and bumps very well, in comparison to my friends hardtail giant with a 48v 1000w kit which is very unforgiving on bumps
Thanks man for sharing! I'am planning doing the same.
🍻 Thanks man
Dude your rachet strap bike stand is brilliant!!!
Thanks man! It's not fancy but it does work 🔥
Very interesting build. Like you've probably already heard, I would definitely use torque arms (Grin Tech or custom ones) if this were my bike but it is your bike. You really know what you're doing with electrical stuff.
Thanks, this frame had steel inserts for dropouts so not the same as pure carbon in this area. Carbon is actually stronger than steel, so I was confident they would hold. Plus the way I ride is not stressful on the components.
I will be making a new carbon bike soon, and it will be about 5x the power this has 👍And yes that one will definitely need TA's.
Very nice build
Thanks man!
Awesome build, very similar to my bike 👍
Thanks man!! 🙌
Love it, exactly what i am building now, just minehas 2 motors
Awesome! 🤘
I'm getting ready to do a 72v build on a full suspension mountain bike frame, the rear strut is taking up triangle space.
My remedy will be TWO triangle packs in parallel with a 120amp coupler, I will hang them left and right over the frame with a foam spacer to keep them from interfering with the rear strut.
A little more weight, but I will double capacity 😅
Great video, getting me excited about my next build 😁👌
Thanks man, I will be making a 6KW 72v full suspension bike very soon on the channel, I have to get creative with making my own pack to have it all fit. I wish you luck on your build, I'm sure it will come out awesome! 🍻

A frame for it
@@dredfxcustompaint That's awesome man, I'm sure he can make it fit 👍should look great!
This was a great build!!! I would like to see you do a build on a fat tire full suspension frame. Headlights(led) and rear light with turn signals
Thanks man, I will see if I can find one I like and make a build of it.
you are right, the spacing is the hardest part. i had the same problem. what i did was, put the thinnest washer i could use to make it a tiny gap for the cassette side. and for the caliper side its trial and error. all bike frame are different i had to use 2 washers on the other side to make my caliper line up,
This is probably the hardest part of a hub motor install, but once you know the issue it's easy 👍
You rock!
Thanks man!! 🍻
if you want an alternative to xc90's have a look for QS8-S anti spark connectors, you can use heavier 6AWG cable and 120A+, it's what I'm swapping mine out for
Thanks! Yes, I usually go with XT90s's for the spark arrestor, but I'll check out those connectors too!
Bit late now, but ALWAYS remove the plastic spacer on the brake rotor side, it’s only there to stop the Allen bolts going to deep in the hub until you put your rotor on 👍
Thanks man!
When putting hub motors of over 1000 watts, please make sure you are putting those small metal torque arms on to prevent the wheel from ripping loose at speed.
Thanks man, I actually made a video on torque arms and why I don't use them on a lot of my builds. 👍
@@hightech-lowlife mind linking to it?

🚀🍻💪
Awesome
Thanks man! 🍻
If you lay the bike upside down, installing the rear hub becomes much easier. It also ensures that the wheel is installed evenly.
100% I do this on some of my other builds 👍Thanks!
Try learning to true spokes this way that is an art in itself. Bicycle mechanics in shops are fast like Kung Fu. This is an art form for sure keep practicing. I'm scared of my first build but I'm going to do it and post it asap.
Hey man, I do work with ebikes as a hobby too, and I have some tips for U...
1- Almost all the time U can take a 30A controller and push 50A, search for shunt mod and you will understand...
2-I think that controller is gonna fry in that bag hahahaha
3- keep doing videos XD greetings from Brazil
Thanks man! I may do a video on pushing a controller like that, the only thing is that most of those cheaper low power controllers are not designed for the heat output, so while it may work for a short while I'm skeptical of the longevity of slamming the mosfets over and over without adequate cooling. I suppose you could integrate a fan or something like that, but never attempted yet. Could be a fun project though 👍
I haven't had any issues with heat from the motor or controller, but I also don't abuse my stuff much so could be just my riding style.
Thanks for watching man! Greetings from USA!
@@hightech-lowlife Agree
@@hightech-lowlife I'ma computer guy and I have laying around some water coolers, I always wanted to put one in those ebike controllers hahahaha
@@TheBirells It would be a cool idea, I used to be into water cooling computers a long time ago (maybe 10+ years ago) it was fun 👍
My battery also came with the big AC computer connector, seems a bit dangerous considering you can plug it straight into 120VAC 💥
Yes, I almost always swap to my own connector preference as a lot of mfg's will use gigantic connectors that are not necessary. 👍
I was going to go carbon fiber but I was afraid that it will break trying to fit the qs205 in that drop out.
Oh yeah man, the QS205 is stout, I would only feel comfortable putting that motor on a "traditional" bike frame if I reinforced the dropouts quite a bit. I think you could still do it with carbon, just would need to modify the dropouts to be more robust. This particular frame had steel inserts for the dropouts, but with a QS205 I would want to weld even thicker parts to that to make sure 👍
what would you esitmate as the electric range of this bike? awesome build btw
Should go 30-50 miles depending on how you ride it 👍
thats pretty much what I want to build for my next one, minus the carbon frame, I would probably use aluminium. I don't see too many channels making bikes like this so its hard to know what parts I would need, particularly the choice of motor and whether it will be limited to its rated watts even with a high power battery and controller.
Awesome man! Yes, once you understand how the electrical systems work you can get a feel for a more accurate power number that is beyond some ratings 👍 Thanks for watching!
aluminium can brakes after to long use , i have build myself a bike like this and i use a fake stealth bomber frame , but a project like this is much work takes much time just you know that dont rush on a project like this
Where do you source your kits & batteries from? I'm in Ireland & everything is astronomically priced low quality. I've been looking around for the same type kit as yours. 2000w with 45/50a controller. But no luck yet
[I'm not sponsored by *anyone* BTW, just for transparency sake ] Go here: www.aliexpress.com/store/1100891991 they made me a special 50A controller kit to take their 2000W hub motor kit to 3600W 👍
Are the dropouts carbon fiber too? How is it handling the added torque on the dropouts?
This bike had steel inserts in the dropouts, I didn't have any issues with it 👍
Great video! I see your disc brake mount was rubbing on your rotor and you fixed it by removing the spacer on the hub motor disc rotor. I am having this exact same issue however I already removed my spacer on the hub motor. Yet the disc brake mount is still rubbing on the rotor. any recommendations? At this point I'm considering filing down the disc brake mount.
Thanks man! The first thing I would check is if your dropouts have the correct amount of washers/spacers between the motor and dropout, most likely you need to add more spacers which will more your dropout further from the hub, thus giving you more space for your caliper 👍
If you have the correct spacing and cannot add more room - check out if there are any other bracket adapters for your caliper size to space it out even further. The brackets have a bit of play but if you're maxed out to one side and still rubbing you may need a different adapter. Good luck!
@@hightech-lowlife Dude this worked! You rock. Added a spacer between the frame and hub motor and now no more rubbing! Thanks!
@@abesview5855 That's awesome to hear man! I'm glad that was the issue 👍 it's always the little details that can be tricky. I try to highlight those things in my videos when I run across them because if it was something I ran into then probably others faced it too. Good job fixing it!
hey! great video! i was wondering if you have any tips for building a E-BMX, i am very confused on what type of hub motor i should get
Yes I actually have a full BMX build on my channel, check it out: czcams.com/play/PLGIzSUqaQbL6U9TXgcDikVMjm-CSSoDuf.html
@@hightech-lowlife yea i have watched it like 3 times, still cant figure out what hub motor i need
@@SnarkyRattleTrap How fast are you looking to go? I think 1500W is plenty and can be done pretty affordable
@@hightech-lowlife yes i was thinking that too, is there anything else i should look into before buying?
@@SnarkyRattleTrap Most kits even the cheap ones are pretty decent, just plan out what size battery you want and where you might fit it and how you want to mount it 👍
Thanks! how many miles throttle only do you get?
With 20Ah, should do 30-50 miles 👍
Not an ebike channel but I love the builds regardless. Keep up the good work. Ever thought about doing an E-go kart?
Thanks so much man!! I am thinking of maybe a 3-wheeler
@@hightech-lowlife that’d be sick! I’d watch that. I wanna see someone do a three wheeler with three hub motors.
@@En3rgyLee Oh wow, 3 hub motors that would be crazy! I'll think about it. Thanks man!!
You happen to have a link to the battery and controller?
I also have a 2000W hubdrive and I'm looking to upgrade 😅😅
The particular seller I purchased this from is no longer carrying these kits. However there are a lot on AliExpress if you do a search for 3000W kits 👍
Can you provide links or tell me where you got all the parts? Amazing build!
Thanks man, this frame is discontinued as it's been a while since this build (actually made in 2019) however you can use the frame of your choosing (one of the perks of doing a DIY build). The seller I purchased this hub motor kit from is still active however they have removed most of their ebike listings, so I cannot directly link as that product page is no longer there. I did purchase this kit on aliexpress however, and if you do a search for 72v 3000w ebike kit, there will be a lot of results.
If you do want to build your own ebike, I don't actually recommend just finding some links that someone else gives you as it's possible that there is the same kit or battery sold by a different seller at a significant discount as all of these merchants will compete with each other to give you the best price, so it pays to cross compare the features and offerings of more than one.
I will be making a video tutorial on how I find and source parts as I get these questions a lot. Thanks and good luck 👍
Excellent, even a year later
Thank you!
You should twist the wires before you soder them or just use butconnecters if you're too lazy to solder them right. Other than that nice build. Good cable management
When the gauge is too large it's cleaner to solder this way, twisting just turns into a mess, been doing it for decades without any issues 👍 Thanks man
I have a 1500 watt motor 48v battery so I can get a 72v battery and a controller that can handle it and it will make it faster?
Yes 100% 👍
Plase tell me, Will a bafang 48v 500w motor be fine if i run it with a 72v battery?
No, that is too big of a jump. If you want to use a 52V battery, that is ok, but 72 will do damage to your controller most likely.

I have the AVADECK Carbon Mountain Bike, DECK2.0 Carbon Fiber Frame MTB 29" is this bike compatible to convert?
Sure, you can convert any bicycle into an ebike 👍
I've been riding this bike for 7 years now! czcams.com/users/postUgkxHL1v1R3NE5x4KiYfyt8dnQmyNYz7qi5L It was a great bike the day I got it, put it together, and went on my first ride; more importantly it's an even better bike today. I've ridden trails, street, and skatepark all on this bike. I have replaced almost every part on the bike. Some stuff has broken: derailleurs, wheels, shifter. Everything else were upgrades. The only ramaing original parts are the frame, bottom bracket, and crank set. BB and cranks will be upgraded soon. The geometry isn't great but that is really the only draw back to how good a value this bike is. Even after all the money I've spent upgrading it's still a more affordable bike than I'd have bought from a proper bike shop, especially with full suspension. I've also learned a lot about bikes working on it over the years. It really is one of the best perchases I've ever made and hopefully it'll still be around for another 7 years.
Yes it's a medium sized frame 👍
What is your battery constant and Max discharge Amp ?
For this build? I don't remember the specs, but the controller could do 50A, I believe battery was 40 or 45 👍
I would absolutely have replaced that phase wire connector thing, either MT/MR60, Anderson's or even just bullet connectors.
Screw terminals work just fine, only a bit less convenient if you have to disconnect it with much speed. I usually leave enough slack to change tires without needing to disconnect the hub though 👍
Great, build I still haven't decided to purchase new or build from scratch. The build from scratch with power like yours the cost is about the same as new?
There aren't many bikes even available with this much power, from my experience if you build your own you get about double the power and range for the same price. 👍
I do have a Trek 4300 maybe 🤔 I will tackle it.
@@HB-yq8gy Try it out! I think you'll be happier than something off the shelf 👍 It all depends on your goals though, for some people store bought with a warranty makes more sense, nothing wrong with that, but if you're into DIY at all, I think you'll find more options, power and lower prices if you're willing to build it yourself.
Your full write-up with pics is on the main site page not found? If I decide I would like your trusted parts & battery. I heard ebike quality parts overseas"Amazon" are not always equal or overrated. Thanks love to get started!
I found the full write-up on your cruiser video thanks!
Good
👍
Are the dropouts also made of carbon? Either way, I would recomend you put a torque arm on. I heard that Carbon fiber bikes can't handle the torque of the motor.
It has steel inserts for the dropouts, I never ran TAs on this bike and never had an issue 👍
1:11 - People that give you crap about modifying Walmart bikes obviously doesn't know the difference between the cheap Walmart bikes and the better ones, for example the carbon Hyper frame has better hydraulic brakes and upgraded shifter components which make it a decent bike... Some of parts on the other hand are crap like the tires/tubes, bearings, headset, grips, cranks/pedals/chain. Parts like that are pretty much the first thing people upgrade so that's why they have cheap parts on them... Then after that it's usually the shocks/forks and maybe wheels then you have a really good bike for a decent price point.
Thanks! I 100% agree, as with everything there are trade-offs. Most "premium" bikes to me do not justify the prices they're asking, you will pay triple or more but I don't believe you are gaining triple+ the amount of value. 👍 Same for any other brand, you pay a lot for the name alone.
@@hightech-lowlife - Yup and just look at some of the high-end bikes, even they come w/ cheaper parts because they know it's probably the first thing that's getting upgraded like the seat, grips, tires and brake pads.... Even though you spent more, you still have parts to upgrade.
@@xpndblhero5170 Yeah I had a lot of people telling me the frames are going to break or crack, I've never had a bike where the frame itself broke - not that it's impossible, but very unlikely.
Do you have links to the stuff used in the video?
I would but the frame is discontinued, the seller I bought the kit from no longer sells ebike kits and the battery seller as well. When searching for the best deals this can happen as a lot of sellers will carry the same or similar parts and you can shop around and get them at the best price. I will be making a how-to find ebike parts video, and that should give you all the info you need to source any parts for any build 👍
i wanna see u build a electric mini chopper bike that woud be sick right mini yea that would be sick
I might do it in the future man, thanks for the suggestion 👍
@@hightech-lowlife swatt im ear for Mon RocK Em Bro!!!!!
Had the same issues with the dropout and the power wire getting rubbed by the screws on the disc brake. This kit is kind of a pain at first. Mine is the 2000w and I'm curious what controller you are using as an upgrade
Awesome man, it's a good setup! This is a 50A version, I'm not sure who makes the controller (as I bought it as a kit and they told me to get the display I'd need to upgrade to the 50A, the one that comes with the kit is 35 or 40A) but it's some KT-style controller 👍
Where did you get your controller bag ?
It came with the kit, there are tons of controller bags available on ebay/amazon though, check em out 👍
I'm researching a mid drive motor on a carbon Niner gravel. I hesitate because of fear on frame failure due to motor weight. Whats you experience with carbon frames and motor?
Carbon is stronger than steel 👍Mid drive motors are lighter than hub motors typically, but weight shouldn't really be a concern at all in regards to the integrity of the frame (beyond specific things like hub motors and dropouts, but that wouldn't be applicable here).
@@hightech-lowlife I m looking at Cyc stealth and Cyc X1 pro. Looking at mounting im wondering about the bikes cables under the downtube interference with the motor. My Niner is in great shape. No issues at all and never crashed
@@debbieschwartz3132 As long as the cables have clearance and won't be pinched/smashed there shouldn't be a problem. I have a 29" mid drive build coming up soon on the channel.

How much mileage can it do from 100% to safest lowest battery percentage?
Range is hard to calculate with precision as so many factors affect how far an ebike will go. I'd say on average this should do 20-40 miles on a charge.
Can you do this on a middle suspension bike ?
I've made multiple full suspension builds on my channel already 👍
Hey could i add a bigger wheels to it so it doesnt feel as small?
Bigger wheels? No, most frames are designed for a certain sized wheel. If you enlarge the wheels they will interfere with the fork/rear swingarm/frame. I think you mean fatbike tires? They are not interchangable without extensive modifications. If you want a bike with big tires/wheels start with a frame that accommodates them.
@@hightech-lowlife thanks also I love that you replay :)
@@User94827Z. No worries man, thank you 🍻
A better controller would be the Phaserunner. With a 21s pack running on a BBSHD mid drive to 5.1kW, it will get to 57mph/93 kmh.
Thanks man! I will be making an alum frame mid drive in the future 👍For high wattage builds I don't particularly like mid drives - usually regular bike chains don't like 5KW put through them for very long 🍻
@@hightech-lowlife I've only been through 2 chains in over 4000km with a mid drive and 5kW. They're stronger than you think.
@@sigmaoctantis_nz That's pretty good man, I've only made 1 mid drive and didn't have any chain issues. I have seen a lot of people on r/ebikes blowing through chains (and sprockets) every 2-3 months on only 1KW BBSHD. I'll have to make more mid drives and find out for myself though 👍

@@hightech-lowlife cool. would you recommend a torque arm for a 36v 350W motor? or is that not necessary
@@merlijntjetovenaar1004 If your frame is steel and the dropout thickness is sufficient then I personally wouldn't bother. If it is aluminum then I would. 350W is not a lot, just make sure your axle nuts are tight.
Whats the range on this ? Also would this kit fit a bmx style bike? Im looking for something to commute to work 26 miles round trip but don't need to do 45mph the whole way.

"Full write-up with pics is on the main site" the link to this is broken. Could you provide a working link to this please? I would really like to read the full write up because:
- I would like to see how it was built exactly
-I would like a full parts list so I can do it myself.
Thank you
Sorry man, the site and write-ups have fallen by the wayside in terms of catching up. I will remove this link for now, thanks for letting me know.
I have a few videos that are more step by step in regards to putting a hub motor on a traditional bike frame: czcams.com/video/L0SnN9du-Ac/video.html the same steps apply here.
I don't have a full parts list because this frame is no longer sold (discontinued). However, you can use just about any frame you'd like, and if you pick a carbon one, you can use that.
The seller I purchased the motor kit from is no longer selling any motor kits, but there are many available. This is 3000W, so if you want the same performance, there are many available.
It's hard to provide links to exact products as they change quite often from the sellers and are either updated, changed, or discontinued. Same goes for batteries, this is a 20AH pack 72V.
Usually when I make a new build I just search for what I want as I can't even rely on the sellers and links I've used in the past personally. Also, one seller you purchased from may be marking things up at a later date, so it's a better habit to search for what is available at the time, and do a comparison to get the best price. 👍
Part of the fun of a DIY build is sourcing and finding the parts you want, as you can tailor your build to exactly what you want. If you don't want to do that, you can always hire someone to pick and assemble the build for you. Thanks!
Where do you get your parts and your batteries and that battery case
The case came with the battery, I bought it off eBay! Search for 48V 20Ah triangle pack 👍

About 1k, www.aliexpress.com/item/2251832082112160.html - but you have to ask for the upgraded 50A controller to get 3KW.

hey man i have a jasion e bike from amazon and want to switch to a 72v do u think it’ll work? I know it fits but the battery is $550 on amazon but no returns
You'll have to do more than just get a new battery, because you won't want to put 72v to a controller that is designed for 48v 👍
It depends on what you're trying to do? Just go faster? How fast is the bike now?
@@hightech-lowlife it goes 23mph i was thinking the same as your 45mph but i’ve seen other of 52v would those fit then?
@@hightech-lowlife and also what’s the things you need to install a 72v? Is there a way u can just buy a 72v controller and attach it?
@@killshot6933 If you get a new controller and battery then you can go with 72v, depending on the motor it should hold up but maybe not, it depends on how many amps you're pumping through it.
to go 45 you'll need roughly 3-3.5KW of power. 50A @ 72v is about 3500W, so you'll want a battery that can output 45-50A (preferably RMS and not peak) and a controller that can also handle that 👍
If you go with 52v battery it will go faster, but most likely only 3-6mph faster than 48v
No torque arm on a carbon fiber frame? Is that safe? 🤔 Nice build btw
I've never run a torque arm on any of my builds and never have broken any dropouts 👍 This frame has a steel insert for the dropouts, so should be ok.
@@hightech-lowlife That seems to be testing fate a bit. I just built a 1500w hub-motored ebike, and due to the scale of the consequences of running a high-power motor without torque arms, (dropouts rounding out, making the frame completely useless, losing the wheel at 35mph, etc etc) I am running two torque arms, one on either side. It cost me $15 bucks off amazon, and an extra 20 minutes to install on my first try. The potential cost savings is too enormous to ignore.
@@kwadkrazy6078 I've built many (13+) "regular (non enduro/moto)" bikes 1500W to 3500W on steel frames without torque arms without issues. With an aluminum frame it's much more of a necessity (asking for it/tempting fate), for steel it depends more on the frame (and also your controller and controller settings). The frame isn't useless if you round out the dropouts, you just stick a giant thick piece of steel and weld it to the frame and make your own new dropouts that won't break or need torque arms.
Everyone is free to make the choices they want to make for their own bike, if torque arms make you feel safer please put them on (put two pair on, or three). My recommendations are always to do and use whatever methods and accessories that suit your own personal goals, feelings, beliefs, etc. I just go off of my own personal experience, if I was rounding out dropouts and cracking frames left and right, believe me I would be putting torque arms on everything, but that hasn't been the case. Maybe I'm just lucky, I'm not sure, but that's a lot of evidence towards the contrary of what so many people are telling me as a "must".
If it makes you guys feel better I did put torque arms on a new build (video soon), but the truth is it was completely unnecessary.
@@hightech-lowlife Well said, say no more. It's not my place to dictate how you should build your own bikes, and you obviously have much more experience.
@@kwadkrazy6078 It's all good man, I'm all for people bringing their anecdotal experience, ideas and thoughts, but it's also important (at least to me) to challenge those ideas and beliefs (especially my own). I don't think torque arms are a bad idea, and certainly won't harm anything by installing them (aside from $20 lighter and a bit more fiddling when having to change your tire).
My apologies if I came off rude, I've just been told things like this many times so far and I question the validity of the persons understanding when stating things as fact when I believe the truth requires a more nuanced view. If you want to share your experiences with others to help them, that's great and I encourage that, it's genuinely helpful. The things I don't believe are helpful are people just regurgitating things that others have said and speaking it as if that is their own belief through personal discovery, or talking from a position of authority with no foundational basis for that position nor authority. I'm not saying you're doing this or have done it, just explaining my viewpoint so you understand.
I will make a video on the subject of torque arms, just because I think it's worth talking about and even if people don't agree with me, I'll at least have a video explaining why I build my bikes the way I do.
Thanks man, I appreciate the feedback.

@@User94827Z.Fitting the hub will always be the hardest part of a build but it's still easy, it would be a lot easier with a steel or aluminum frame as you can bend the frame slightly to allow more room. Carbon does not bend. 👍

For one the kit I bought is no longer available from the seller, you can get this www.aliexpress.us/item/3256802089966534.html but you'd need a 50A controller upgrade to get to 3KW and I don't know if they will do that if you ask them.

What do you think?
@@hightech-lowlife broken for sure, unless your sell it and not one knows
@@testdirver A surprising amount of people think that carbon is weak, not sure why they think that as if they did any research they would know it's not. Also I see a lot of fear and panic over improbable scenarios. I make a lot of builds to try things out, if I was having issues (breaking frames, breaking dropouts, etc) I would report on it and say so on my channel. I would let other people know my experience and they can draw their own conclusions.
A lot of people also have predetermined beliefs that are devoid of any experience or data, and hold on to those beliefs even when there is hard data showing otherwise. If I was breaking carbon frames, I would avoid using them in the future, and show others my experience (with data to back it up). There are a lot of people that think you need to spend $5000+ on an ebike otherwise it is not "safe" and that the frame will immediately crumble to pieces. It's fine if you want to hold these beliefs personally but trying to convert stranger's minds is just a waste of your own time and theirs. It's even worse if you are less knowledgeable and experienced than the person you're trying to convert.
There are a lot of factors that go into the stress of a material, are any bike frames breakable? Sure, but I've never broken a bike frame, so if breaking frames is a problem you have there are solutions to solve that problem in many ways. If you have broken every bike frame you've ever ridden, then you probably would break a carbon frame, but that would be more of an issue with how you're using it than a fault of the material or construction. It's possible that if my idea of riding my bike was sending it off 1000ft cliffs to rocks below for fun, then I'm pretty sure this frame would get broken, but that's not how I ride my bikes.
I will be building another carbon framed ebike soon, and it will have 6x+ the power that this one had. 🍻
@@hightech-lowlife last year bought a local brand, "cheap xc carbon fiber bike" around $1700 usd, the frame feel solid but wonder if would hold on an ebike conversion, still 3x times the value of yours, so maybe next year bought a 350w or 500w hub motor; glad to hear didnt break

PS
I love you bike 🚲 build 👍🏻
Thanks man! Much appreciated 👍
If you only need 30mph, I would go with a 1500-2000W motor, you will save money and you won't ever use the extra power of a 3000+ watt motor. 1500W is more than enough for speed and acceleration, everything on top of that is just extra. Use the extra money saved to invest in the best battery you can. That's my recommendation 🍻
