Ecotric Portable and folding fat bike model Dolphin


Look at the fat tires and the perfect curves. It is just like dolphins, which are chubby and cute but flexible. It has a 500W power motor, a 12.5AH high-capacity lithium battery, and its upper tube and handlebar are foldable. In addition, fat 20-inch tires provide good shock absorption. All this means this is a portable e-bike that you can ride for a long time on any road. And I couldn't come up with any other better options.
Max Speed : 20 MPH
