Abstract
Bicycle rollers that include a frame and front and rear rollers mounted in the frame, each having two lateral ends. Also, a pair of bumper/rollers are mounted on the frame adjacent both sides of the front roller. They are mounted so as to be horizontally rotatable, thereby acting to constrain a wheel of a bicycle supported by the front roller from moving laterally off the roller, while not stopping rotation of the bicycle wheel.
