Many people associate the step-through bicycle as being for women, however, they are convenient for any gender. The big advantage of step-through bikes is that they make it easier and much more comfortable to mount the bike. Your feet will be able to touch the ground and there are no worries about losing your balance and possibly falling while trying to get on it.
Built to last with top quality components, big hydraulic disc brakes to stop you in all conditions, and front suspension to smooth out the bumps, this will be your go-to-bike time and time again.
The Stunner LT 6 750W Fat Tire Step-Through Cruiser is one of the few eBikes offered in 3 different frame sizes which can accommodate riders between 4'8" and 6'6". Size matters.
