Up and Over Engineering has made mountain bike technology available to the wheelchair rider with the Cobra Off-Road Wheelchair. The four-wheel disc brakes, knobby mountain bike tires, and directional steering enable wheelchair users to enjoy the rugged ride offered by back-country trails.

The Cobra is easier to ride when the user’s center of mass is as far back and low as possible when going downhill, and as high and far forward as possible when going uphill. A mechanism that adjusts the rider’s center of gravity to an optimal position without fundamentally modifying the wheelchair frame was needed.

the solution

A lightweight frame structured to support the seating was fabricated and installed onto the Cobra frame with reinforced Kydex linkages. This minimal modification allows the seating system to swing up and forward in the wheelchair using a four-bar linkage.
