Hello

You can see my electric conversion of a YSR to e-YSR here http://motoelectrique.unblog.fr

- powered by 240 A123 cells (48V 34Ah)
- 3000W brushless 13'' hub high speed
- color OLED display - LCD display
- sound and voice speaking, alarm, capactive BMS, regeneration, xenon high power light mixed with LED ...

I'm waiting for next generation batteries

to have more autonomy.
Actually I'm looking for new smallest PCBs without relays. No more cycle analyst and cell Log too.

Bike is very pleasant. In most case you don't need to use brake because of regeneration and acceleration is impressive and without noise.

On the picture you can see the (blue) battery box instead of motor.

On the two next pictures, you can see the battery box (240 cells A123) at the beginig of experience. This is not definitive motor (now disk braking system and more power).

--> Note this bike is allowed for road use <--

You can see a video for display here:

and a video of running bike here (with flat tire

)

Hello Bowen

I take a look at your link but I don't think you can put so much power in a YSR body. YSR is a small bike and, or this conversion, motor is in the frame, not in the wheel like me. Of course, you can use A123 cells (as mine) to have big discharge current but, if you want an high voltage, you will not have place to put every cell or you will have to decrease Ah so distance will be very low.

It's a nice project but I don't think it will be really a good one because, to have speed and distance, it need a big frame.

Orphee,

He's got a hubmotor....

and its only a 3000W hubmotor, so its not going to be very powerful, but it'l have a good amount of energy.

Nothing wrong with this conversion, but he's going overkill on batteries for a 3000W motor and its going to be a bit slow.

So he have the same motor than mine

no more than about 70km/h.
The best thing to do to have high speed on this bike is to buy a 7000W 72V hub. Here it would run at more than 100km/h but ... in a short distance
