i cant seem to get the speed im going since its bouncing so im thinking about getting a digital speedometer
i would like to get a gear indicator too
the bike is in good condition beside when is 1st gear and bellow 3-4k rpm its like i would try to come off a stop in 3rd gear in a car and it doesnt seem like its supposed to do that
