The Copenhagen Wheel project has been a long time coming.  In fact many bike enthusiasts may have even forgotten the concept debuted 4 years ago at the UN Climate Change Conference.

Now engadget reports the project has been completed and you can now turn your bicycle into a extended range/power assisted EV for only $699.

The concept is simple and the tech is designed to "snap onto a standard 26-inch bicycle wheel, converting your ordinary bike into a powerful hybrid electric version that can cruise along at 20 miles per hour."

The company says that Copenhagen Wheel's  48-volt battery has a range of up to 31 miles.  As it is self-contained, there is no throttle, but rather you just increased pedal speed (as you would with no battery on board) and the motor will compensate with additional power.
