Abstract

See full text

The preferred embodiments provide a frame for a one person three-wheeled human powered vehicle, the rear portion of which resembles an upright bicycle frame capable of supporting a fixed rear drive wheel substantially in alignment with the frame centerline. The frame has a left-side lateral extension and a right-side lateral extension, each of which includes a head tube at or near its outer end where front forks or steering posts can be secured. Each front fork or steering post can then hold one of two front steerable wheels. The frame is compatible with shock-absorbing suspension technology, which can be employed if desired.
