Abstract: An off-road chair comprises a U-shaped chassis configured to receive a rider in a wheel chair type (manual or electric); at least one wheel attached to the chassis; and a floor section. The floor section is configured to attach to the bottom of the U-shaped chassis and to provide a floor; be lowered to provide a ramp for the rider to get on the floor section; and be raised to attach to a bottom part of the U-shaped chassis. The U-shaped chassis is configured to receive a wheel chair type (manual or electric) carrying the rider. The off-road chair further comprises a front bumper attached to a front of the U-shaped chassis, wherein the front bumper is configured to swing up with respect to the U-shaped chassis, enabling the rider to get on the floor section; and be lowered to lock to the chassis and protect the rider.
