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.
