Abstract
A three-wheeled all-terrain vehicle or push chair utilizes an innovative front wheel mount, employing a side-mounted caster mechanism, for improving its pushability and steerability. Because of this approach, lifting is not required to steer the chair, and any size or type and width of wheel can be used. As a result, the invention provides a new class of all-terrain product for the disabled adult market and a rugged, truly off-road runner/jogger/hiker stroller for the young child market.
