Step-Through frame

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.

Dual integrated battery system

Range worries are a thing of the past with our dual battery system. One battery is embedded in the frame, while the other is mounted within the triangle of the frame. This positioning maintains stability, with no noticeable effect on your ride.
