Abstract
A stable, low speed, powered tricycle with traction steering, includes a pair of freely rotatable traction wheels and corresponding pairs of friction rollers and braking surfaces that are selectively engageable therewith to effect propulsion and steering of the vehicle. A caster wheel supports the front of the vehicle frame. This forms a tricycle rolling system that maintains stability by automatically broadening a turn to obviate tipping.
