This Class III E-Bike is ideal for rides to work, running errands, and speedy cruising. Its 500W rear motor can hit 28 mph and offers pedal-assist and throttle modes. A wide seat, fat tires, and front fork suspension provide a comfortable and stable ride. Its battery pack is removable for charging and juices up in 3 to 4 hours.
This unusual bicycle can expand to carry up to 180 kg (about 396 lb) of cargo at its center. Its rear wheel and drive chain fold down and out to provide extra space as needed. It’s also available with a pedal-assist electric motor to give you added momentum when carrying heavy loads.
