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 strucuture attaches to the hub and holds the wheel secure and upright. At least one of the supports has a quick release for capturing. 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 connnected 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.

Abstract: A velocipede, for example a bicycle, having a front wheel drive is disclosed. The front wheel has a gear axially mounted thereon. In place of regular handlebars is a drive gear rotatably mounted on the upper front of a frame. The drive gear has coextensive handle means for rotating the drive gear. A first drive chain connects the drive gear to a plurality of different sized gears. A second drive chain connects the plurality of different sized gears to the gear axially mounted on the front wheel, whereby rotation of the hand means causes rotation of the front wheel. A derailleur is provided to change the position of the second chain on the plurality of different sized gears. Independently rotatable coextensive handles with cables extending to the outside allow for brake levers and derailleur levers to be mounted on the handles without becoming entangled during 360 degree rotation of the drive gear. The gear wheel is lockable to provide fixed handlebars.
