I don't drive it on main roads or busy roads, I usually drive it on the sidewalk or in parks. I've road past cops on bikes, motorcycles and cars while I was driving it on the sidewalk; they don't seem to care. I know if I was driving it on busy streets with other cars then they would say something.
Yeah! That smaller sprocket is wayyy too small. If you want more top speed change your sprocket out for maybe 10-20 teeth less. Depending on what u currently have. Keep in mind ur losing torque by shrinking the sprocket(less acceleration)
the motor itself has a 11 tooth sprocket on it, and that small black sprocket is a 22 tooth sprocket(made it myself). The sprocket that got me up to 32mph has 54 teeth. I just bought a 37 tooth sprocket that I will switch out with that small 22 tooth sprocket. Hopefully I can reach 40+mph with it
