You might recall that we blogged about the Smart Wheel on November 22. The Smart Wheel is produced by FlyKly and is an amazing motorised insert to the wheel that actually assists in peddling, boosting your speed.
Now there is another product called the Copenhagen Wheel by http://www.superpedestrian.com
The Copenhagen Wheel was developed by researchers at MIT in conjunction with the City of Copenhagen.Tthis device snaps onto your bike and helps you conserve energy. And it does it in an ingenuous, remarkable way.
The wheel t stores the energy that you already use, and saves it for when you need it most. Hills become flat, and you no longer have to expel loads of energy to get around. Curious? Watch the video for more information.
