In this video we are going to redo the conversion on our bicyle using a powerful brushless motor while replacing the old geared DC motor.
Earlier we have converted our bicycle using a geared DC motor, though the conversion was sucessful and we were able to get thing rolling but still the top speed and the torque provided by the DC geared motor was miserable.
So we decided to step up the game and eventually we come up with the idea of using a brushless motor from an old hoverboard and some high discharge lithium pollymer batteries to give this bike a puch of power.
The conversion was stright forward as we tried to eleminate as many unwanted parts as possible during the process and thus we were able to achieve a top end speed of nearly 40 km/hr (The bike is surely able to get double that but the speed controller we had was able to handle only six cell lipo pack) and the torque was phenominal, seriously wheelies on the go.

i had made something close to this but didnt re wire the motor, used a cheap sensored controller, and had way too low of a gearing... i had 3d printed a tpu adapter for the bottom bracket of a bmx bike to fit the shaft of the hub motor. I like your solution... the torque you have got out of that motor and gearing combination is wild! Props!!! thanks for sharing!
Excellent project
Very cool bro 👍🏻 Super comfortable to watch.
awesome man i thnik its the only diy channel in pakistan with good vloging skills
Hi, very nice work Brother, simple and easy. You are great.
That’s amazing,Excellent Conversion👍🏻👍🏻👍🏻
I love it. I wish I had that bike. Great job and god bless you sir..
Great job bro!!
Great work brother just love it
Great work and good wiring keep it up
very good and quality conversion done...keep it up...
I would like to see someone convert 2 electric bicycles into a four wheeler that is also electric.
Check the channel jegringeverything
jerryrigeverything did that
Congrats Guys!
Good job, bro! 😎👍
Great work & alternation,
Keep it up boysssss
Great work❤️
Well done young man

Good work bro
Great explanation about this project. Keep going.
That look great well done great job
Very good idea and job ...I want very well one lake these ...good luck mister ...kadatis from Algeria
Great job bois keep it up
Love it 👍🏼
Awesome top man
V good work,. Pl explain how you used battery, how much potential it should be
Nice work .
Cool! Subscribed!
Hey Buddy!!! Long time no chat!!! Loving the new workshop and really liking your design on the bike......90K subscribers........Your kicking butt!!
Yo Bhai you are the great. Love from Nepal. Mujhe bhi ek aisa hi electric bike bananatha Bhai.
Really amazing even I have such practical hobby to do, hope I will do that one day. What basic reference do you recommend I mean the knowledge about motors, wiring and so on so that I can learn. Please do suggest me...👍👍👍 thanks
Lovely bro
I like your video keep up the good work 👍
Smart built
Good work 👍👍
Have you got the drawing on how to re-wire the hub motor? Only video/pictures are not enough for a good reference...Thanks!
Gostei,um belo projeto
valeu💪🚴
Nice motivating
😊👍
Great, Congrats
Great to see first time who made Cannes in winding to increase the torque. I believe the it will increase the current draw of the battery and cause less run time. Just let me know does it affect battery run time compare to last set up. Thank you.
Very nice done ✅
A fun, practical & affordable ebike
Love this video, can you do a diy esc 400A 22s with a controller or throttle ??
Excelente te invito a que hagas más videos i te motives a su fabricación i comercialización saludos desde Arequipa peru.
good video,
Maravilha !!! Parabéns.
Love from INDIA🇮🇳
Very cool
Great project. I wish there was more detail on how you altered winding of the motor.
Me too
you are amazing !!
Super bon boulot 👍
well done video, but how much kms it goes on a full charge, my office is 30 km and I want to now if you can put this motor in hub for me
Thanks
Yogesh..Goa
Looks like fun...
Yeah! Love it
04:48: Where you get the hub which allows to install the disc from both sides?
How did you put tension on the chain??? Looked like it went on real easy...meaning it would come off easy?? What am I missing??
Hello DIY King, thanks for sharing. Just a quick question: can the xiao mi escooter motor also be used?
yes. inside its exactly same motor
where can I buy such sprocket, mounted in place of brake disk?
Climp any hill with a small boat starter motor. If you were 90 degrees with front install, it would flip the rear up so you could face plant the wall/mountain/rock. If it were rear, you would be flying up the stairs in a wheelie. Make sure to feather the brake. Take one of them diesel lithium battery starters rated at 110v 100amps with a pwm(pwm brush only much stronger than brushless..brushless made for long distant constant...not best for torq). So yeah, Stunt guy like you, use a small starter motar which could pull a car at 2,000 lbs. Infact for the ultimate short burst that will climb anything use a 300 amp pwm(max hard to find- can get 150amp pwm) and you could flip get air on those stairs and flip with perfect landing. Another thing you can do is upgrade you control box to 5,000 watt 96v and overload brushless(500 watt brushless handle it for short bursts 5-8sec under heavy incline . 750watt 8-14. 1000 watt for 19-25 1500/1800 26-36 2000 47-60 and a bit over. 3000 1-2 mins.
Well Bro How Much Torque does The Motor Gets And How Much Volts Does The Motor Needs And What ESC did you used In this Project And Whats the motor and ESC Specs here
Fun video
Excellent project I love to see the innovation!
Good project.. but please give more information about the part you use like the battery and the cre ..
Can you Please explain the rewiring of the motor in detail. I got it was in series and now it is paralell, but how ?
can you share me to increase the speed of hoverboard motor and the pcb board i want to build like what uou have done thanx more projects to come
Pedal pads are ok in position or try to turn and fell off? Or you fixed them?
nice, i have suggeston, plase make a motor with paddles and cadens sensor and gear motor like those in abroad of bocsh or Yamaha you are already close
Hello dear. When can we get some more details on how you rewinded the coil of the motor and eliminating the hall sensors please?
No rewinding, simply from Star to Delta, gives √3-fold more speed, but equaly less torque. Would be cool, if he could switch back and forth between the 2 configs, so 2-gear e-motor...
@@klausbrinck2137 All right, so is there any point, to refurbish the moto inside, instead of setting up a simple mechanic bike gear to change between more speedy or torquey outcome?
@@IUbU 1st: You save electricity and so get higher range. 2nd: You don´t have to use yout legs, you use the motor after all... So, there is 2 points there already. And he doesn´t have 2 electric gears anyway, he just chose to switch to the 2nd gear permanently.
Elimination of hall sensor is in e.s.c. not in motor.
Hello your new conection in the motor is triangle? No star?
Bro what was that small black box component you used ?
Can u do a conversation video dedicated to making this motors faster?
What if I use ceiling fan motor instead of hoverboard motor??? What changes would I need to make???
Thanks for the info. Appreciate if you can provide the subtitle please.
hello
can i use a bipolr stepper motor in e bike??
if yes then how?
Hi, do you can show the step by step of connecting the motor to obtain this torque?
Did you find a video?
Please tell me how to connect the circuit of motor of the hoverboard. Please
Nice
super!
What battery is suitable for a motor in terms of voltages and amperes
From where u buy that sprocket
please!!!!! give more detail about the rewinding process i want to complete this same project
A small help if u can
Convert cycle chain to a duplex chain
Pl if possible
Some excellent work here but some of the decisions are a bit weird. Perhaps it makes sense if this bike project was intended more to be a video, and less about actually using it. The things I would have done differently were:
Found a way to keep the pedals so that you can still pedal if you run out of battery.
Used a thumb throttle instead of a servo tester.
Used a VESC ESC because its current control method is so much more suitable to ebikes than the typical duty cycle control (it's a nightmare starting to turn on the electrical power if you are already moving with a duty cycle based ESC, it causes it to brake rather than accelerate).
Add more heatsinking to the motor, it'll get quite hot trying to use it like a moped.
Salam
Can you guid us where to buy hover bord motors ?
I have a radmini with a 750watt rear hub and 48v 14ah battery but is slow can you help to make it go faster
Hello friend, how's that plate that you stick on the engine of the hearer? What would be the name of the plate so I can search on this site?
It's an interesting design, but you got the essence of a bike, which is the pedal of the bike! If the battery gets empty somewhere for any reason, it's no longer a bike.
Dude you're cool! 👍 The success and development of your channel.
Who gets excited about 14km? This guy!! All that work just for 14km
You should get a 72v 60a kt controller and run this on 20s max. Reccomend looking on the endless sphere forums for ebike research. Great build though.
Bro please drop the link for bldc motor controlor u used in thi :)
How about install s modified solar panel for charging on e bike ?
Lagay rahoo...
Hey where did u get the adapter for motor axle to fit into bicycle frame
App ne konsi engineering kri hai plz tell me
