ABSTRACT:
A bicycle trainer has a horizontal frame. Pivotal hub capturing supports are attached to the frame. A bicycle wheel hub is situated between the supports where opposed hub capturing structure attaches to the hub and holds the wheel secure and upright. At least one of the supports has a quick release for capturing the hub. The quick release has a piston with a socket for fitting around the hub. The socket on the piston is urged towards the hub by a spring biased cam having a lever attached thereto. The structure supporting the rear wheel of a bicycle may be used to support the front of the bicycle. The rear and front wheel portions may be connected by a telescoping arrangement to allow for different lengths in bicycles. The rear tire rests upon and is in frictional engagement with a roller attached to the frame. The roller is tensionable by way of a brake actuated with an easily accessible push-pull cable. The roller supporting the front tire is not provided with a brake but is connected to the rear roller by an endless belt.
