Description
The Dolphin is an affordable and sleek folding bike that hides its electric system in the frame and seat post, MXUS hub-drive, 36v 14ah battery, 7 speed Shimano cassette, thicker tires, and mechanical brakes with inhibitors.
It folds well, so you can walk it when folded or even slide the seat post down through the frame to use it similar to a chair, allowing you to sit on the saddle of the bike while it is folded.
FREE WITH PURCHASE:
Dolphin comes fully outfitted with fenders, head light, rear light, bell, tool bag, thumb throttle, and kick stand.
