You built a rocket ship there Steve.
Remember your helmet & gloves when you do your test rides because everyone's Nana will be watching and we don't want them to spit their tea out on the rug 😂
😂😂😂🙌
That is class. I always wondered what combining motors would look like, I suspected it'd involve some wiring like that. Your cube is going to go 0-15.5mph in no time at all 😂😂
I should do a 0-15mph test 😂🙌
Love your bike builds you have saved me hours of grief with my builds by watching you solve the difficult problems with custom builds. Keep it up.
"I'm going to scribe round the nut, and with absolute precision" *sound of grinder dies off
"All we need is a flat surface" 😅😅😅
😂😂😂
Love it, I bet this build's a tonne of fun, imagine the power from 3xmotors?!
I can't wait to see the ride video!
A suspension seatpost would be a nice addition .
NB Power made me a custom 2000w front hub, I'm getting my 5000w Rear on Friday, will post the video. Pretty sure I'm the first with dual 72v motors, the trick is battery storage, which took me a year to master.
I was thinking of how a 3 motor E-bike would work yesterday then this pops up on my feed. I'm glad to have watched this mad man do what I couldn't have.
The name of his Channel, fits perfect and discribes his " work" perfect!!
love it need absolute precision ...next clip ..whopping big angle grinder .....what could possibly go wrong ....It worked ..
160mm is you, 220mm is the man she said is just a friend 🤣
As for the bike, absolutely mental in a good way.
Thanks to this guy getting into details i slapped on my first hub motor the correct way with the spacers going in the correct order.
🤙🤙🤙
@@DudeStuff your a living legend, probably saved my life too.
You’re a mad lad dude! All kinds of sketchy but I can’t wait for the road test. Make sure you’re wearing safety winter sliders when you take it out for h & s reasons 😂😂
Haha ill dig out my special winter sliders 😄
Wondering if you could help me I bought an Andy Kirby kit same as what you've got there 2000watt max mtx 39 hub motor. I've successfully done just under 2000 miles on the rear hub motor and I'm starting to get a little bit of sideways play in the for example if I wiggle the wheel from side to side I get a tiny knocking noise it's literally only 1or2 mm .starting to worry me have you ever experienced this if so how can I rectify it take in take any mind I'm not very clued up lol .❤
ps you are a mad man for building a triple motor push bike it takes a certain type of somebody lol
Maybe your hub bearings? I bought a motor (not a andy kirby)and they went after a few rides just had them fixed but they have been fine now.
@@gaviscon4304 was it expensive or did you do it yourself if you did it yourself was it a hard job
Luckily it was still in warranty and they did it but it's not that hard I would of done it myself, you just take the side covers off to get too the bearings if that's the problem, pull them out and replace with new ones they should have a size written on them so you can order the right ones. Hopefully this helps 👍
Wow- I hope you’re using sine wave controllers, with the right parameters, you could make this thing ridiculously fast. I have a feeling you may run out of rpm on the mid drive. I’m soo looking forward to your next post (no teasers……😉😉)
Just a little tip. Never use plastic brake disc, spacers stacking even amount of washers on each stud. The plastic ones compress let the bolt loose and cause mayhem later on down the road
Yoo! That’s BA. I had thought about putting another mid drive on mine.
This is the type of bike I need I got the steepest hills in the world where I live. One motor doesnt even touch the sides I reckon that bike could get up that hill of the spot with out a run up.
Always knew you were mad, this video confirms it.
If you do the 2000w in front again instead of attacking the forks with the angle grinder try machining the nuts down in a lathe to fit the recesses in the forks.
I tried something similar on the first build already. I ground the flange to match the nut, and the corners were still hitting the recessed aluminium when you tried to do it up. I purchased nuts without a flange. Custom washer everything was tried on the first build I still needed to grind a bit away.
Been keen for a triple motor build like this for years! Yes! It's gorgeous ❤
🙌🙌🙌
This is awesome great video I can't wait to see the next video
And the grintek cycle analyst display I think has multiple throttle inputs and allows you to digitally split them. You can even program soft start front motor, full start rear motor all in wind, throttle and display
This is pure “Dude Stuff” gold. Great inspiring build, and brilliant video👍👏. I ‘was’ seriously thinking of dual motoring my Z8, but now I ain’t so sure. Not lease as I ride it in all weather. Thank you for showing me the error of my ways. That bikes a beast and will need Lion tamer size minerals to ride😂 Looking forward to the road test. Please include some hills.
Haha, brilliant thanks will definitely require some hill tests tests flat out 😁
Great video! Just a heads up for next time, I found that a locking C washer could be used as a spacer for the front dropouts so you dont have to file down the edges. I have around 3k miles on that ebike so it seems to be sturdy enough! As someone who built a dualhub motor ebike and used it all through last winter (Including submitting a mountain) how many screws do I have loose? I knew I should have used thread-lock…
I used washers on the first build but found they was incredibly tight when using to 2000w hub motor due to the axle being larger. Anything substantial enough to grab onto was too big a diameter to fit into the fork dropout bevelled area. Probably works OK for a 250w, 500w or 1000w hub but I've found it incredibly tight for 2000w wheels
@@DudeStuff good to know! I’m running a 1200w 29” ebikeling kit on the front and a 3/5kw 27.5 from NBPower on the rear. Top speed is 60mph and it gets you there quick! I dont even have the front running at full power, it burns out so often and already puts quite a bit of stress on the front fork at 1kw, looking forward to seeing some speed runs with this build!
I use velcro type cable ties from the dollar store to tidy up the wires on my builds. My daily has lots of wires cause it has an extra brake cable that runs to my bike camper brakes, and a trailer harness for charging, etc. And two motors and two controllers. Brake lever switches...usb cables for my lights. The velcro cable ties look nicer than zip ties and can be used over and over. I still do use regular zip ties as well, but the velco works better for bunches of cable.
Another mad creation 🤣 I live local to you, I’ve got a Kirbe bike 1500w single motor running just over 4000w @52v, should compare the two at the same voltage and power, 1 motor vs 3 motor 🤔🤣
Love the builds mate but use a dremel mate not a angle grinder so much neater
I reckon this beast of an ebike you just built is more powerful than that infinity mirror stealth bomber frame ebike you got in the backgraound. Please, do a review on that ebike as well. I havent quite seen a video review on it.
Cheers mate.
That's Robs bike from @dredfx channel its not an ebike yet we're planning the most budget friendly way of making it an ebike soon.
The most awesome, ludicrous (in a good way!) pro build Frankenbike ever! Keep on building!
this where useing a cycle analyst is needed it allows to compensate for voltage drops when outputing to multiple controllersand each controller has its own current shunt so it tell whats what
Your crazy!!!! but i like the concept their always a way to do something and youve exelled in itwell done love the build cant wait for the next video
Thank you so much 🙌
YES!!!!!!!!!!!!!!!!!!!!!!!!
Y E S ! ! ! ! ! ! ! ! ! ! ! !
Thats definitely not messing about! love it
i probably would have tried having the mid-drive motor on the throttle and having the other two run exclusively peddle assist, acting as a sorta turbo for the mid-drive
It’s a good day when you upload , looking forward to this one
Thank you! 😊 🙌
on a dual motor setup yoh have only one display for 2 motors
... so both hub motor use same settings, same pas level etc..
maybe also third can be connected in parallel ... just di the same on the display as you did on the other wiring
“We need absolute precision” pulls out an angle grinder 😂
Your awesome
Ah thanks bro 🙏
I wish I had the money for one of these builds. it's so cool. To have that freedom to leave the house with bad lungs like this amazing job. Great ideas. I love the content, guys. ❤
Always love watching your videos I always learn something new 👍 the cube is gunna beast 💯 it’s always a good evening when you post 💯👍
Ah thanks for your comment 👍
Steve my dude this must be one of your craziest creations to date but I love it can't wait for the test Launch, wear a helmet mate 😂😅 that the bike has more torque than Andy Kirby.
😂😂😂
🎄👍🎄👍🎄👍🎄👍🎄👍🎄👍Hi what a brilliant video I think your a top bloke this was a fantastic idea hope all works out well
Keep up the brilliant videos
I always leave a like 👍 👍👍🎄🎄🎄🎄
😁 thank you 🙏
OK whens the raffall for this one. Cant wait for a hill test up MT Snowdon
Instead of grinding metal off of the fork, why cut a washer to fit in the space? That way, you get more metal, giving you more strength and tightening force.
17:20 I would like to see somebody one day make a pair of electric training wheels from the motors / Wheels of an old hoverboard on something like a 29" Cruiser hybrid 😊😅😂.
It would be something like a Satyristic portable Universal conversion kit that would have a very simple bolt on frame containing battery Motors controller and wiring fully configured and ready to go like a hot swappable server hard drive just tighten the two Wing nuts or something like that but no clue how to work out a throttle and display that I could easily and quickly switch from one bike to another.
An idiot-proof install like they do with the friction wheel drives that the one I saw just bolted onto the seatpost and I know it sounds weird but if nothing else I'll need to build one just to get the idea out of my head but I'm thinking I might need to go with pneumatic tires if they make them in the 6" - 10" inch range or whatever size those are on the little hoverboards you see at Walmart for like $100
Put nut on bolt, put bolt in drill, spin it around and file the nut smaller so it fits in the hole and you don't have to make a dog's dinner out of the nice forks.
Bro, grind the washer and not the forks, magnesium is brittle enough Without removal of materials.
Doesn't work I've tried, even without a flange the nut and corresponding washer is too big.
@@DudeStuff It works for me. Just saying taking materials from the structural places of the vehicle is not a good idea. The lowers of the forks are magnesium and brittle enough Without removal of materials.
MADNESS!
I love it, great job
Damn !, Dude .
Lap around you know where!
Please let me come and watch. I can hold a camera 😂
lol someone wants to buy my hybrid I was like nooo it’s to dangerous.
Amazing build , great seeing some of the issues with fitting not for the faint hearted but what a machine !!
Need to get some shrink tubes that have the solder in them
i can hear NJ 'tutting' at your soldering from here! nutty build, can't wait to see you doing some off road on that beast!!
It's got way better than it used to be 😂😂😂 but NJ is the man
change the cap heads in the hub to button heads 5:35 give you more room
You should of used some heat shrink on the wire's would be more safer m8
Can this be done to an existing dual hub bike? Separate throttle, battery and display
I'm in love with this bike ,well done brother ❤🎉
Your a a mad man dude stuff 🤜👍😂😂
Hi I made duble motor too I whant to ask u are that forks are aluminium??? Cos I snap aluminium forks with 1000w motor and I du screw in torque arm both sides.... ur one are steel one?
Wow! Not a clue about anything you said but wow looks like a monster
23:50 thanks for the video that is a very interesting build and I'm looking forward to the test drive
A washer or two would've been way better than grinding it bro! Great video man!
Explained in other comments already I've tried that doesn't work. Thank you 😊
Im loving this build ... this is NutZ ! 🤩
You wouodnt happen to know the name of the frame colour please ?
cool video, I can see how much hard work you have put in, therefore I paid £2 in the compeition simply to support you 💪👍
Thank you 😊
A lot of your build issues would go away if you
a> had kirby kits which use a through axle
b> and which would fit a modern boost width fork.
QR would not feel good with me anyway when you're getting above 2kw, it would probably be fine I know but a through axle would make me feel more secure.
qr is 135mm, boost is 148mm, it would solve all your clearance issues and if Kirby had a kit which supported a through axle you just wouldn't need to modify anything on your dropouts / fork.
Using boost also pushes your chain line out, which isn't all that great for a mid drive since the smaller cogs which you're likely to spend most time on will be a couple of mill's further out. Ideally your chain line should be as straight as possible in the gears you're most likely to use the most.
3 motor ebike is mad btw, I mean there is no way I could even ride that on public road even if you had it limited the coppers would immediately 'not trust it', think I have a 'secrit button' to unlock it on the fly and thus impound the bike for a technical 'review'.
And then I could be out of a bike for months while they 'techy cops' try to figure out wth you build 😂
Also, haven't heard you mention in the video itself but that middrive is tsdz2b with vlcd5 right? Which firmware are you running on it?
And even when you explained what you did with the wiring, I'm still a bit confused. I would be worried that the hub motor and mid drive would not be 'in sync' with each other based on a single throttle input. It's also a bit confusing, those hub motors will push more power then your middrive ( unless custom firmware and cooling mods have been done to it ). Even with those mods, controller is maxed at 18A and it can't handle more then 56v peak, since you're using a 48v which maxes out around 54v fully charged that's 54x18 ~ 972W .. but this will overheat the motor pretty quickly and you'll end up with demagnetized magnets ( and thus a lot less power ). Unless you done all the cooling mods. Or if it's a newer tsdz8, but then there is no custom firmware for it yet afaik ( nothing on endless sphere at least ).
I love my own tongshen, it's great value for money, but for a crazy build like this I would have thought you went with something with more power out of the box, like a Toseven if you want to keep your torque input, or just a bafang if you don't mind a cadence based support.
Looking at it btw, it could be a Toseven.. could be but I think it's a Tongshen?
203mm disk brakes becomes useless if you use regeneration
I am not sure those hub motors support regen braking out of the box?
Also, even if they do I would still want a second backup system.
@@nicod974
@DudeStuff you're fine with the throttle joining since I watched again and you mentioned the kirby's also use a 5v max signal voltage which is the same as Tongshen.
Not really seem any though axle hub motor but that would be sick and open up a lot of new possibilities
Where do I find 1000w geared hub motor?
thats sickkkk
Yes bro, I bet that's a beast!
That's a beast :D That bike has a potential to crazy fast acceleration
🤔 METAL SPACERS WORK WELL 💯
I would Love you to build me a bike they always look like a factory job and they alway make 15mph look fun 😂 I love the Chanel keep up the good work
Bro serous question what is the waiting time for these kits to arrive I've got my battery delivered just wait on my motors but its been 8 days an still haven't received it yet 😕 not happy with the waiting time at all I'm loosing out on work at the moment 😞 😢
man thats sweet, Ive never seen a battery cry.
Can't wait
So I live in a really really steep and hilly place, I haven't been insane enough to even consider adding a third motor to my setup but I gotta say having awd on rough dirt roads with incredibly steep incline is truly a life saver, and I'd already upgraded to having a second battery for extra range so it wasn't even that pricey. No rear suspension absolutely sucks though and its the biggest reason I want to ugprade, it'll prevent you from taking this kinda build anywhere it wants to actually be. Awesome stuff though!
Great, what's the weight? Pulls strong on take off, smoke tires?
Super well done. I’ve got a front wheel electric motor 1000w. She moves like the wind.
This is insane cant wait for the ride video!
So also thinking 2 battery packs 42v front bigger for back to match motor. Merged throttle. ? What u think?
What about adding a switch to stop the signal from the throttle to only use the single motor to be road legal and the option to turn up the power of all 3 motors running together when off road wink wink as we all are law abiding citizens and only would use a maximum of 250watts on the road 😂
10.28 "turning freely" whilst dragging
How do you do your controller what I'm assuming is a brushless DC controller
What size is the frame on the raffle bike?
I will check it's either medium or large
It doesn't say what size but post tube is about 18 to 19 inches I'd say its fine for anyone medium to large frame 🙂
Always good to see your videos, best wishes.
is the 2 motor drive wheelchair still a thought ?
camera looks funky at the start
It's official you are barking mad lol but i love it, and well done great project can't wait for the road test vid, gonna be interesting to see how you balance the different torque from the 3 motors (probably adjust individual power settings )
Very nice. And the soundtrack amazing what's its a song please
1000w front 2000w-3000w rear is best way to build an AWD
Thats sick dude
5.41 "it's not rubbing", whilst dragging on wheel
I want to see you carrying that tank to 3rd floor.
there is 3 different motors on there ,will never be able to get them all in sync to share the load and get the power down itll be push and pull thing
Electric motors work very differently to combustion engines, it’s actually really easy to gauge and configure
i design and build high end custom bikes and if guaging a near enough is ok for you ,no probs ,but when your looking for maximum distance ,no power wastage, safety and traction control,effective maximum regen production,we achieve these by utilizing can bus protocols ,use this for controls ,buttons ,bms ,controllerslive suspension actuatingall lights and accessories,but hey what do i know ,as you said electric motors work different @@stabbawivagun
Both you and Andy are the Dream Team absolutely Disgustingly Phenomenal Fuccck Tesla youze need to incorporate and just Fly !!!
Hi love it can't wait for the video to come out looks to be supper quick setup just one thing to say "don't try it in the garden as you may end up fixing your workshop doors lol" but yeah keep the good work up love the content and can't wait for the next vid all the best mate and be safe.
No offence bro but the aluminium forks are not strong enough for the front wheel torque I kno I had a nasty accident so I mate metal sleeves and fork drop outs
Absolutely insane, you've outclassed yourself yet again. Keep it up and really looking forward to the ride video.
Hello mate i see a build u done recently using the grin tech phase-runner with the cycle analyst display screen I’ve got the same set up with a 72v battery I’ve messed around with the settings and made it really slow I can’t get it back how it was before could u send me some 72v setting please
Hey sorry that was ages ago and don't have any settings and never used 72v sorry
Man I was just talking about this the other day and that cockpit isn't even close to what I imagined it would be I knew it would be a spaghetti bowl but holy hell lol
