Product Description

The U8 Ultra is the long-range model in the U8 family. Its 48V 18Ah battery gives up to 105 miles with pedal assist, so you can ride for several days of commuting before you charge.

A 1500W motor reaches 28 mph and keeps a steady pace up hills and on loose ground. The aluminum frame sits on 26 x 4.0 inch fat tires with a front suspension fork, which together soak up bumps on pavement, gravel and dirt paths.

A Shimano 7-speed drivetrain covers hills and flats, and integrated lights help you ride after dark. The IP65 rating protects the electrics from rain and splashes.
