A:Answer Hard to say. I am 200 lbs, and I was able to go 20 mph on the flat roadway, battery at 85%, app unlocked. After you enable the Speed mode, you have one more step in the app to allow it to reach the "22 MPH". According to what I have read, the 22 MPH was achieved on a flat surface with a 165LB rider....from their website:
" [1]Max. Speed: tested while riding with a full battery, 75 kg (165 lbs) load on pavement. "
