In this video I am converting a full suspension mountain bike into a powerful E-bike with a large 967Wh battery combined with the Bafang BBS02 mid drive motor kit, capable of just over 1000W of peak power, 120Nm of torque and up to 100km (62 miles) of range. Great fun, high speeds of over 50km/h (31mph) and reliable parts by Bafang. The battery is mounted to the frame without drilling - using 3D printed supports that hold the battery in place after more than 200km with no issues.

in my opinion this video is one of the best I have seen. The battery build was very clear and straight forward. I built a ebike last year out of my 2014 Devinci with 29 in wheels . A jack model, I put high end commuter tires and a 1000 watt bafang with a48 volt 17.5 ah battery. It bench tested at 99.3 km/h and road tested at my max. so far at 74.3 km/h. that was flat out as hard as i could petal for about two min. lol. 46 tooth on the front. I have about 1300 km on it so far, gone through a chain , two tires, a cassette, and a set of brakes, yes I have pounded this this , but very pleased with the bafang kit. I am craving more power as become more accustomed to the bike . I rarely drive anymore and very inspired by my fellow ebike do it yourselfers. Thanks for your lesson on how to build a battery, I learned alot.
Wow, thank you so much! Truly means a lot to me. Will have to try the BBSHD myself, hopefully this summer. Were you able to pedal at all above 50 km/h? 74 km/h top speed sounds scary haha. The Bafang really is a nice kit to use.
Yes, I am able to pedal at,around, and over 50 km. As one can imagine, you have to be careful in traffic of course, it's the other you got to watch lol. But because I live a little ways out of town I'm able to get onto secondary roads with less traffic and higher speed limits, and that's where this thousand-watt really shines
No words, yet so clear! Congratulations for a job well done!
Thank you! Kindly appreciated.
@@DonnyTerek quanto é
Wow, proper battery mounting solution as that is always the weakest link when mounting a big battery to a tubular aluminium frame. Very nicely engineered, respect.
Thank you! Didn't want to drill this nice looking bike so these mounts work really well to hold the battery in place.
Absolutely brilliant job, best video showcasing how to do a good job I've seen in a very long while, I will most definitely be recommending your CZcams site to as many people as possible, thank you for a great 54 minutes of something actually worth watching. ❤
Perfect build ...thats the level of ebike building i aspire to get to
Thank you!
Beautiful build! First class work all the way through.
Thank you! Much appreciated.
Excellent combination of bike, mechanical and electrical skills.
Thank you!
Outstanding video! Great camera positioning & lighting & very high build quality! Many thanks!
Thank you so much! Kindly appreciated.
Wow that was amazing.. alot of knowledge needed to build a battery from start to finish
Thank you so much!
purer Genuss dein Video 🤩😍
Ich fahre seit 4 Jahren mit 2,7kWh-14Kg DIY 14s11p Akku 21700er hinten drauf und jährlich 13.000km 😅 aber Front Directdrive Motor und neuerdings Sinuswelle Controller ...ein absoluter Traum diese komplette Ruhe aber trotzdem Drehmoment ohne Ende ☺
Nice! Clean installation and custom build.
Much appreciated, thanks!
Man, thats a lot. Now I have a greater appreciation for their expense. And, that's just the assembly aspect, now think about all the manufacturing - from the mines to the smelters and, whew! Fantastic, fantastic video.
Thank you kindly! Mean a lot to me.
Amazing engineering and great craftsmanship.
Thank you! Much appreciated.
You are a genius in presentation and engineering skills. Thanks a lot for your work.
Thank you kindly!
Flawless! You are so talented.
Thank you! Much appreciated.
Very nice engineering... Congrats! As a motorcyclist, I would not recommend positioning the lights side by side as this creates an illusion of being far-away-car to oncoming traffic . Question: I noticed the 6x14 array battery has independent cable routings (balance wires) giving you 3.57V to 50.0V : How does that work? I would assume that this is designed for battery quality correction (?) Is this working with the controller or the charger? Thanks!
It works with the BMS. The BMS has to know the voltage of each group of parallel cells so it can keep the cell groups relatively in balance during final charging. As an option, you can have an additional separate balance unit that balances faster but still needs the BMS unit for over and under voltage cut out, over temperature etc. One bad or weak cell group will be detected by the BMS and will shut down the whole battery even if the overall battery voltage is acceptable.
Thank you kindly! Since I don't use this e-bike on roads with traffic, I keep these lights pointed quite low to light the road close to me. But I agree that it may look like a car approaching. Yes, the battery has 14 independent cables from each group of cells to monitor the voltage and balance the voltage of the batteries. The BMS (battery management system) board takes care of that, which sits on top of the battery.
Great video, you give me another reason to transform my cheab bike in an e-bike; a big hug from Rome(Italy) in this hot day of sunday!
Thank you so much! Glad to see I may have inspired you!
Awesome video on battery building. Thanks
I can't believe I've watched 54 minutes CZcams video
Simply amazing 👍😃
Thank you so much! Glad you enjoyed.
Great build... And it's quiet like an e-bike SHOULD BE...👍🤪
Thanks!
Man you sure do good work. So eat. Such clean sokders and stuff. My compliments, and I am a very critical guy!
Not very critical of grammar 👍🤣😉 sorry couldn't help myself
@@jordancoleman2402 HaHaHa, thinking the same thing dude! (prob just typo's on a cell phone)
Thank you so much! Means a lot to me.
You Sir are a BAD ASS. Thank you
Thanks!
VERY CLEAN INSTALLATION! KUDOS!
Kindly appreciated, thanks!
Well done mate. Very thorough job on that spot welding.
Thank you! Kindly appreciated.
Muito trabalho para montar uma bike dessas , apesar de ter ficado muito top.....parabéns ao biker !!
Congratulations for a job well done!
Great video thanks I'm looking to make my own battery, this is a must, the bike is beautifully done.👍
Thank you so much!
Great video thanks I'm looking at making my own battery this is essential viewing 👍
Thank you! Much appreciated.
Master work 👍🏼💪🏼💯
Amazing! Well Done!
Nice awesome concept bike battery power pack yep
That is the ultimate 2 wheel transport. Cheapest to run. Easy to maintain and will go everywhere that a car or pedestrian can go.
A great machine! Even if your battery runs out of juice, you are still left with the ultimate ride--the Shimano pedal transmission, which needs absolutely no electricity and no gasoline to bring the rider home.
It really is! I definitely agree.
Great job! Are you considering larger rotors and perhaps 4 piston calipers just for more pressure on the brakes?
Edit...watched to the end and so you did😁
Thank you! Yup, unless I find a reason to put 6 piston brakes 😂
that's so clean
Thanks!
Damn you really have a lot of patience to round up all those batteries. Up voted for the effort.
Thanks!
Thank You
It’s so complicated,only GENIUS like you who can do what you did..
It is actually not complicated at all if you don't build the battery yourself.
Am impressed!
Very professional build ❤
Thank you!
Cool. I made quite the same setup, but printed custom box for batteries and controllers and used ready batteries setup.
Awesome! Would love to see your setup.
Very cool setup! Why all of the redundant battery jumpers? The first one makes a full connection between the lateral straps. Maybe 2 or three for connection security?
Very good and complete work.
Kindly appreciated.
I watched the complette video. Great Work & Video. U inspired me. Greetings from Berlin ✌🏽 have a great day.
Thank you so much! Means a lot to me. Greetings kindly accepted.
Thanks, respect!!
Thank you!
Impressive to say the least
Respect!
Amazing Best video master Man👍
Thank you!
Hi thanks for sharing this great build. 😃..Would it be possible to do a short video on the programming part please ? Cheers 👍👍👍
Hi, thanks for watching! The programming may sound and look difficult but it is very straightforward. There is plenty of info online, I used the very first link that popped on search: electricbike-blog.com/2015/06/26/a-hackers-guide-to-programming-the-bbs02/
Fantastic bike!
Couple of questions:
1) You began with a "Mountain Bike". Would this work starting from a "Hybrid-style" bike? (This seems to be a Bottom-Bracket fit question)
2) Was that a 10 speed rear cog you installed? What kind of rear-hub spacing is required for that?
3) This is the _second_ mid-drive ebike conversion video I've seen that goes into great detail about the Speed Sensor, but _totally_ ignores the SHIFT sensor! Please explain.
4) What does the entire bike cost?
5) Why did you re-build the front fork?
6) I noticed you did not show balancing the batteries. Is this un-necessary for an e-bike?
Reply appreciated.
Probably work better with a hybrid, due to the spacing around the bottom bracket area.
You need a suitable freehub - need to put a wide range cassette on, as you lose all but one chain ring.
Not everyone uses a shift sensor. Some people can ride a bike and back off for shifting, or jab the brake insead.
The bike looks ancient, with lots of cheap Chinese crap on it, to try and update it. Shop around, prices variry wildly from place to place - try PSWpower
It say in the vid - fork service - you are supposed to do that occasionally.
The cells would be balanced before assembling into a battery, and it's very long and boring (but not as bad as the battery welding)
Besides the battery we can learn how to do the suspension maintenance and other great stuff.
That's a nice build. I'm putting together a 750 watt 52v mid-drive ebike kit on my gravel bike right now. ( July 2023 )
Thank you! Would love to see the finished result of your project.
Well done!
I love the way you created the fixing gadget of your battery holder thru 3D printing, hahaha truly amazing of creating tools nowadays. But i'm still sides of doing things thru conventional way though it may takes a long time.😂😂😂. You are an excellent bike mechanic, Nice Bike DIY works bro.
Haha, thanks! Still holding the battery to this day!
@@DonnyTerek great bro.
Tu vídeo me inspiró lo voy a intentar gracias
@DonnyTerek Great video! enjoyed watching it! one question which 10 speed casetteratio did u use? 11/25..11/32 etc. Thnx in advace!
Thank you a lot! I believe it was 11-36T
And... which chainwheel and breakype..
@@hetfeestcartel6769 44T front chainring and.. break type? TRP Zurich. 4 pot, hydraulic.
Thnx for all the answers, I was very curious about because i am thinking to start building this project with my son
@@hetfeestcartel6769 Glad I can help.
ABSOLUTELY AWESOME VIDEO!!!!!!!!!!!
Thanks!
Very great method shown sir and how to make sweet pack with full detail I got a chance to learn a lot you set up setup in BMSK you have given me a lot of knowledge thanks sir
Nice motorbike. I'd like something like this for my commute if they were legal in the UK.
I recently ordered a 2k watt front wheel 26inch kit for 300$ and a 13a.h 52 volt battery for another 300$. I put em on a 200$ bmx huffy and it would hit 35mph easily and had plenty range. It made me realize just how accessible transportation has really become now. Before
p.e.vs u either rode the bus or has a car or were screwed
2k front wheel, uhm.
@@Stuff-i-Like yup a 2000 watt front wheel motor. Cause they are 100 110 mm and I was using a bmx frame which is 110 in the back
따라할수가 없겠네 ㅠ
전문가나셨네^^
Good job that sht has more cables than my motorcycle 😂 very clean build mate
Thanks! 😄
AMAZING!!!!!!
ЭТО ШЕДЕВР !!! +++ КУЛЬТУРА ПРОИЗВОДСТВА ! СМОТРЕЛ НА ОДНОМ ДЫХАНИИ , НЕ ОТОРВАТЬСЯ!
Amazing work
Thanks!
What motor do you prefer to ride with for touring, mid drive or hub drive?
For touring I'd probably say hub drive. Has more resistance when cruising but much more comfortable riding due to the lack of gears that need to be shifted when accelerating.
@@DonnyTerek I commute every day with a bbshd, I find there is so much gear changing aswell. I'm waiting on a hub drive to arrive so I can try it out. Your channel is awesome, i have learned alot. My new build will be super clean thanks to your tutorials 👍 thanks very much!
@@Christian12284 I can definitely agree. The benefit of the mid drive is definitely the high torque in the right gear, but it takes a few rides to get used to the gear changing. I compare the mid drive to a hub drive as a manual vs automatic transmission.
Your comment is kindly appreciated, thank you!
Это лучшее видео на ютуб, которое я видел... Никому я еще этого не писал. Спасибо! Просто снимаю шляпу.🙏
Wonderful work.
Thank you!
how much po ang ebike nyo sir.
Thanks for sharing this impressive build video. The video and the bike are very nicely done. I was curious if the hydraulic brakes function well in the cold weather?
Yes
Hey, sorry for the late reply and thank you for the comment. No issues for the brakes.
@37:09 Did you put the thermal paste into the Vastfire lights?
The similar Solarstorm X2 comes without paste, bad for heat dissipation...
I was gonna say now add your 3 in one oil!... But will it ride like a Catalac?... Really fun to watch!...
This is impressive and inspiring! nice work!
Question for you, my shift cables run under the bottom bracket of my bike, the mid drive motor will certainly pinch these cables, how do people get around this usually? Thanks!
Thank you!
Which cables run under your bottom bracket to be precise? Front and rear derailleur cables or only the front?
No thank you brother, it inspired me.
The cables for front and rear derailleur run under the bottom bracket. The front derailleur will be gone. I saw in another video, that they just added a rubber spacer between frame and motor so that the rear derailleur cable can run in between the frame and motor
@@Voltermort That's what I thought, a rubber spacer should help. Or re-routing the cables if possible.
@@DonnyTerek appreciate it. Rubber spacer sounds much easier
Hi do you have any problem with engine bending rear wheel to the right side? I have very similar frame in my bike and i want to instal bbshd but i am a little be worried about torque destroing my rear frame and suspenion. What do you think about it?
Those 3D printed things for stabilising the battery is a great idea. I run a much smaller (36V 16Ah) battery, and after my bike fell over, it now sits in a strange angle...
Thank you! And these mounts do work very well so far. The bike hasn't fallen over yet but after riding more than 300 km over different roads and terrain, it holds just fine without any movement.
Congratulations, nice job! Does the BMS disable charging in case of a bad battery or battery cell? If one of the battery cells breaks down while cycling, is it not possible to continue using the bicycle or only with lower performance?
Thank you! As much as I know the BMS does not disable charging if one cell goes bad. You can continue using the bicycle (which is not recommended) but the battery capacity will be lower by one cell's.
I estimate this bike completed more than 7000+ USD ! Congrats !
Piękny 😊
😊
awesome project and great video. interesting to know and maybe is something I could do on my bike.
Thank you!
Awesome clean job start to finish. You should be a trainer at Tesla.
Haha, thank you!
This is the best battery build I’ve ever seen, better than what you could buy, great attention to detail. Is this a smart bms that you’ve fitted, if not, then would you consider using one
Thank you, kindly appreciated. I used a non-smart BMS on this one, works just fine to this day, but of course, having a smart BMS is always nice.
A clean build as usual. But pay attention driving those twin LED lights directly from the Light output of the Bafang BBS. While those LEDs are usually wired in series and run fine directly connected to 6V, the light output of the BBS only has very limited current like 500-750 mA AFAIK. I am using a MOSFET as switch when powering higher current lights.
Yes 500mA is correct
Thank you kindly! Yes, I am definitely aware that the light output cannot reach over 500mA. I actually soldered a 1.5 Ohm resistor inline with the 6V output to limit the current to around 450mA. At first I thought it would be too dim at only 2.7W but it is actually quite bright.

Hi nice video I just wanted to ask why you don't run your motor onto your existing chain and then make use of all the gears thank you in advance
Hi, thank you. Not sure of your question, the motor does make use of all the gears in the back.

Very impressive video. Planning to upgrade my 250w rear hub to 750w mid drive. Pls what’s your your tyre size ? Much love from Glasgow, Scotland
awesome work , my lenkeleisi 400 watt unlock run just hit 42km/h
Thanks!
Just saw you put the black bms wire to the battery negative , I thought the blue wire was to the battery negative and black was out put to load . So how did this work out for you ? Always wondered just what would happen if they were reversed .
in the map youtravel a big distance. please tell how many kilometer did you travel?
WOW!..Could you do a parts list for the bike and electric conversion kit please...pretty please?
Done! Please check the links in the description.
@@DonnyTerek Thank you!
I would add a second battery on top and have the option of switching between them.
I might need longer range than this, but this is very nice and probably cheaper than what you can buy as-is.
You need more than 60 mile range?!? I mean even if you were just hammering it I’m pretty sure you get at least ~29mi or more
@@kimhyunwoo8983 You are damn right. I have almost same battery (14S with 58.8V when it is full). To safe the cells I almost never load above 80%. 60 miles which is about 100km is quite realistic.
For me it is enough to charge about once a week. I have 2KW motor but prefer driving slow. Sometimes I also love to use the pedals and see power consumption goes down real time 🙂.
In rare cases there are tuned mopeds I have to "deal with" what immediately uses a lot power of course.
Thanks for really good video, this inspired me and gave me a few more ideas. Can you estimate how far that battery can go if the speed is limited to 25 km/h?
Very clean clear good job.congratulations.
How much total cast ???
Thank you a lot! I'd say around $1,200 including the bike.
Wao great , looks pretty👍 enough
Thanks!
Wow!! GJ!!!
😄👐
An excellent bike build with a lot of thought put into this build, the only thing that confused "me" was the battery build, the most confusing is the BMS. Any chance of a video on how to build a battery? step by step I would love to see one from you? Once again this was Excellent.👍👍👍👍👍
Thank you so much! I can definitely see why the battery build might seem so confusing. There are simply so many tutorials and info online on building batteries that you can learn from, so I guess my tutorial wouldn't help more. I recommend you read and watch more CZcams about BMS wiring to understand it's basic functions and wiring. From there it won't be too difficult to understand the battery wiring itself. Hope this was of any help, best of luck and thank you once more!
Yeah well this guys is clearly a professional at assembling that battery.
Haha, thanks! Not my first build but I wouldn't call myself a professional yet.
Is it possible to by that battery already done?
Where is the bast place to buy a kit like that?
Thanks for the video
Hi, thank you for watching. I have included a few links of assembled batteries in the video description if you would like to check them out. Links to the kit also included in the description.
