The original intention of the HPS Domestique electric bicycle is clear at a glance. It is the lightest electric bicycle on the market. Using the skills of a former Formula One engineer, Domestique weighs only 18.7 pounds-a quarter lighter than most electric bikes. The motor and battery are integrated into a handmade carbon fiber frame and concentrated together to provide the best balance. The HPS Watt assist system weighs only 3 pounds, can assist with three hours of assisted riding, and has an output torque of 14.75 ft-lbs. Only 21 Launch Edition will be produced.
