This is the electric mountain bike that traverses off-road trails and hills as easily as it rolls across pavement. Its 350-watt motor drives the seven speed Shimano gearing, propelling the bike up to 20 mph. Two 28" mountain bike tires provide traction when negotiating tight turns or speeding across loose gravel and dirt. The fork has a shock-absorbing suspension that helps stabilize rides over rough terrain and provide comfortable landings from trail jumps. The frame is made from lightweight yet durable aluminum alloy and its disc brakes allow riders to easily reduce speeds and stop with confidence. A removable battery provides a 40-mile range from a five-hour charge using the included adapter. Supports riders up to 265 lbs., between 5' 6" and 6' 2" tall. 72" L x 41" H x 15" W. (47 lbs.)
