rudy Change the tire size in the settings of the controller, that gives more performance out of stock the motor doesnt go full peak 750w.. By changing tire size to smaller u trick the controller that vehicle is moving slower.. U can find serial number under lcd find manual and go to settings to do the changes.. if you cant find it contact me... Have the same bike can do 45km/h at max charge, could go 50 but dont want to stress battery/motor and my safety.. 45km is as fast as one needs to be.. faster than car traffic in my city and I overtook several gasoline scooters along my way.. The peak was 600watts going 45km so this bike can go definitely faster, rated at 725w, but not worth the battery drain.. If you buy better battery pack you can also get more performance..

stejerimmanuel I tried but it doesn't work. Changing the wheel size has no effect on the actual real speed. Only the speedometer is lying. Please help if you can. (stejerimmanuel@gmail.com)
