Distinguishing features
This is my commuter bike - typically used downtown, around the U of A, and nearby hospitals. It is differentiated from most bikes by the belt drive used instead of a normal chain, the internal gear hub instead of derailleur (the big gears) on the rear wheel, and a dynamo front-hub (generates power for the front and rear lights).
