The motor is rated at 4500w. The controller is 65 amp, and the battery is 72v 24ah. I've never noticed any problem with the tire slipping on the rim. I usually run about 35psi in the tiresNice. What is the motor/controller/battery spec? Do you ever get the rear tire moving on the rim, or have any safeguards in place to prevent it? I have been looking around at rim locks for bicycle rims for a project but cannot find anything.
Over 10,200 Paul. It's never run better then it does now. The only parts I had to replace was a swing arm bearing, sourced locally, and recently a new battery bought aftermarket on the internet.The bars look great. Bike still looks new, how many miles you have on it now or have you kept track?
