Just a disclaimer to everyone who has tested or currently considering purchasing one of these bikes. The speedometer is set to show a higher number than your actual speed (yes I know its in KPH, I converted KPH to MPH and conpared numbers using 3 different GPS apps just to be sure). I highly suggest using GPS app or unit to get your true speed and some of the earlier posts in this thread may need to be redone. Ill post my speeds once I get my new charger and add 2 additional batteries. Edit: Just found out speed 1 and 3 were reversed and speed two has no function so it acts as speed 1. Read my later post for an update.
