The Copenhagen Wheel, Possible Door County Hill Tamer?

The first commercial version of the hand-crafted Copenhagen Wheel,  invented and built in Cambridge, MA is now available for pre-order.

The Copenhagen Wheel was initially developed at MIT’s SENSEable City Lab as a research project, sponsored by the Mayor of Copenhagen. It has won multiple design awards and been reviewed in over 1,000 media publications, including BBC, Wired and the New York Times – not to mention a glamorous acting debut during a whole season of the TV series Weeds.

Superpedestrian, a venture-backed company operating out of Cambridge, Massachusetts, was founded in late 2012 by Assaf Biderman, Associate Director at MIT’s SENSEable City Lab. They seek to provide new forms of human-powered mobility.

“I read a study that measured the efficiency of locomotion for various species on the planet. The condor used the least energy to move a kilometer. Humans came in with a rather unimpressive showing about a third of the way down the list. That didn’t look so good, but then someone at Scientific American had the insight to test the efficiency of locomotion for a man on a bicycle and a man on a bicycle blew the condor away.” — Steve Jobs

As you bike, the wheel is able to capture energy when braking or going down hill that it stores in the integrated lithium battery pack. Riders are given a boost as they pedal by measuring their effort, instead of using a throttle. This preserves the normal biking experience while enabling riders to bike faster, farther, and easier. All actuation of the wheel happens automatically via the pedals through sensing and control algorithms. When the rider pedals harder, such as when going uphill, the wheel pushes with increasing power. Using your smartphone with the Superpedestrian app, you can vary the level of powered assist.

Currently, a rear dropout of 135mm is required for the Copenhagen Wheel to be installed. Unsure if the Wheel will work on your bike, email your bike’s specs to their mechanic at .

Pre-order your Copenhagen Wheel now at a special early bird price of $699. Visit for more details.
