A Cambridge, Mass.-based startup is ready to bring some of the virtues of electric cars to the bicycle business.
On Tuesday, Superpedestrian began selling the Copenhagen Wheel, a rear wheel for a bicycle that converts the energy of braking and descending into a battery-powered boost when it's time to go uphill or to go faster along the flats. The first products are scheduled to ship at the end of the first quarter of 2014.
The 12-pound Copenhagen Wheel is available for $699 in a single-gear configuration, but it'll cost more for those who want to slip on a cassette with multiple gears. The first 1,000 of them are being hand-built now and will be available for mountain bike and road bike wheel sizes.
The lithium-ion battery recharges automatically when a rider descends a hill or rotates the bike's pedals a quarter turn. And it adjusts its operations automatically, the company said in a statement:
Cheers,
Neal
