Wisper Traditional 705 24" Step-ThroughWisper offers their 705 in a smaller size with 24" wheels, which is specifically designed for those smaller riders. The step through design and smaller wheels make it easy to mount and dismount the bike. You still retain many of the good features of the larger bike, with hydraulic brakes and 250w motor with up to 700Wh of battery capacity if you so choose, just without the front suspension.
