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. The bulk of the front wheel drive is mountable on a pivotable upper support which allows for a plurality of arm extensions. The invention is adaptable to conventional bicycle frames with no modification.
