Default Re: Attempting to convert CFMoto gas UTV to electric.

I've been bouncing between ideas. But have decided to go with a simpler more typical design. See attached crude sketch.

Basically just going to add a large gear to the coupling drive shaft that i removed from the CFMoto gas engine. I will then have a small gear on the electric motor. Everything driven by a motorcycle chain.

This makes it much easier for me to change gear ratios if needed to get more speed or more torque.

So i need to decide on gear ratio. then electric motor/controller combo.
Tires are 24inch. Gear ratio of differentials is 4:1 with these tires. So the gear ratio at the motor probably needs to be close to 10:1

It sounds like most golf carts are running around 15:1

I looked up the Hunt VE cart. That seems to be running a72V system. That's higher than i was thinking. But i wouldn't say it's unreasonable.
