The Bicycles were seen in Cool Bikes. After Mordecai and Rigby trashed The Muskrat 5000, Benson gave them bicycles because their cart privileges have been revoked. At first, the two hated the bikes, but then they decorated the bikes and started wearing cool outfits.
In the beginning, they were red bikes with black tires. They had white seats with a metal back, a pole in the back with a yellow flag, and a basket and white handles with decoration strings coming out of the ends. When the two decorated it, the bikes were painted black and had aluminum foil in the wheels.
