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.

Copenhagen Wheel Available To Order Now, Ships First Part Of 2014
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.
