Folding Electric Mountain Bike: Tame every Trail

Why rear hub motor is preferred electric bike drive method.

Our Folding Electric mountain bike is optimized for hill climbing power. Like all Computboost electric bikes, it uses integrated hub motors at the rear wheel. Hub motors provide the best “torque” as the power is applied directly to the rear wheel. There is no intervening gears or drive train components, like mid motors bikes. Front motors e-bikes also have good torque, but they are hard to steer because of the front wheel traction, but also the center of gravity is too far front (because of the motor). Rear hub motors are best for mountain bikes.

Compuboost Electric bikes with the cantilever frame, has a good center of gravity because the battery (heaviest component of the bike) is centrally located to provide best balance.

High output front light and smart rear lights, plus waterproof electricals make all weather, day or night travel safe and convenient.

Folding Makes it easy to get to the Mountain

Electric bikes are more difficult to transport than regular bikes. The reason is the weight and size. Normal strap on carriers to the rear of cars that hang a lighter bike will not work with an E-bike because the added weight may damage the car or bike or both. Ebikes need either a pickup truck or a cradle style hitch carrier. Unfortunately, hitch carriers usually add 3-4 feet to the length of the vehicle, making many too long to fit in a garage, so the carrier has to be removed when not being used, and installed when needed.

Compuboost electric folding mountain bikes have no such problem. Easily folded and unfolded in seconds, the folded bike can be stashed in the back of even small compact car trunks. An SUV can easily carry a pair of ebikes, with passengers, to get to any trailhead with no problem.
