The HPS Domestique e-bike was designed with a single purpose in mind — to be the lightest e-bike on the market. Drawing on the skills of former Formula One engineers, the Domestique weighs in at just 18.7 pounds — a quarter less than most e-bikes. The motor and battery are integrated into the handmade carbon fiber frame and centralized to provide the best balance possible. The HPS Watt Assist System weighs only three pounds and is good for three hours of assisted riding, with an output of 14.75 ft-lbs of torque. Only 21 units of the Launch Edition will be produced.
