PowerMax Fitness BR-900 COMMERCIAL RECUMBENT BIKE Recumbent bikes at the most basic level are bikes that place the rider in a seating position as opposed to a stationary or traditional seating position consistent with everyday normal bicycles. From here and there are variations but the overall concept is the same. These bikes are often favored for their ergonomic designs which reduce the amount of stress that a rider? own weight places on the points of contact with a bike. On traditional bikes, a rider? weight comes down onto three contact areas: the sit bones, the hands, and the feet. The majority of the rider? weight comes down over the sit bones where they make contact with the saddle.
