Smart Wheel is a pedal assist which means it helps you ride your bike effortlessly. The motor turns on when you start pedalling and begins accelerating to your desired speed. It saves you time by getting you to your destination faster and gets you there without losing your breath or breaking a sweat, and it will stop when you stop! You can remotely lock the motor and track it via GPS in case it gets stolen. It goes up to 20 mph (25 km/h) for a 30 mile (50 km) range and weights only 9 lbs (4 kg).

The wheel cost 590$ and will be ready to ship in May 2014. You can pre-order yours now.
