QuestionI bought the bike based on the advertised maximum speed of 28 MPH. But in reality, it does not go over 20 MPH. There seems to be some kind of limiter that stops the acceleration at 20 MPH. Is there some setting that needs to be changed for 28 MPH speed?
Asked 1 year ago by Ali.
- Answer You can press for 2 seconds the (-) and (+) from your controller and it will take you to the settings of the bike. Then keep pressing the middle bottom on the controller to get to next screen. You will find the option to increase mph to 45 km. Once changed, select de middle bottom from your controller and it will allow you to reach 28 mph using pedal assist. If you use the throttle it will reach up to 20mph only.

QuestionSo your saying it doesn’t go 28 when you press the throttle
Asked 9 months ago by Dion.
- Answer It does not. For me, he throttle maxes out between 16-19 mph depending on incline. With maximum pedal assist I reliably reach 33 mph; low effort down hills, high effort up hills.
