ABSTRACT:
The rider powered vehicle has two steerable front wheels, each with a turning arm, and a single rear drive wheel. Power transmission means is provided between the rear wheel and a single push-pull and steerable handlebar mounted in a column assembly supported to oscillate about a lateral pivot axis. The handlebar is connected to a steering arm, and two steering links are connected at respective inboard and outboard pivotal connections between the steering arm and the two turning arms. Handlebar rotation causes the inboard pivotal connections to trace an arcuate path, and the lateral pivot axis is located to intersect the arcuate path generally at two spaced locations. This geometry provides a propulsion and steering mechanism that has substantially no interaction between the push-pull power strokes of the handlebar, for vehicular propulsion, and the handlebar rotation, for vehicular steering.
