Electric Bike Wheel Kit - MIT Copenhagen Wheel Turn Your Bike Into a Hybrid
A electric bike wheel kit like this MIT Copenhagen Wheel, which is easily interchangeable with any standard bicycle's rear wheel, converts your everyday bicycle into a hybrid. This electric bike wheel kit stores energy every time the rider puts on the brakes and then sends that power to provide a boost when you're going uphill or any other time you need a burst in speed. The MIT Copenhagen Wheel generates can be totally controlled through the pedals; simply pedal backwards, and the regenerative braking is engaged, helping to recharge the system's batteries; pedal fast, and you get the extra boost of power. The wheel also features sensors which via a Bluetooth connection to your iPhone can monitor the bicycle's speed, direction and distance traveled, air pollution data, and even the proximity of your friends.
