If you'd like to experience the ease and assistance of an electric bicycle but don't want to get rid of your regular bicycle, you might want to consider the Centinel Wheel -- a wheel that can be swapped out with your bike's rear wheel.

This wheel, which is set to be available first in a 26-inch wheel size, is equipped with a microcontroller and a pair of 180-watt motors that can be taken out for upgrading. A 24-volt 13-amp lithium-ion battery can be taken out for charging.

The Centinel Wheel is also fitted with a Bluetooth module that allows it to communicate with an app on iOS and Android smartphones. The app allows users to select their degree of electrical assistance. This degree of control is sure to be appreciated by cyclists, particularly those more accustomed to regular bikes.
