Hey I would like to get some input on getting my GEM electric car programmed to reach the speeds of 40mph if someone could help me out. Thanks

Shouldn’t be a problem that about $2,500 in bigger wheels/tires, larger controller, new gears and 7.5 motor won’t cure. That’s provided your batteries are still good and brakes are up to snuff. :welcome:

Need more information. Not all are capable of high speed.
Year, controller, motor, battery, tire size, gear ratio, brakes?
