What is the benefit of the Nitrum wheelchair being ultra lightweight?

The overall weight of the wheelchair is one of the factors that contribute to rolling resistance. When the rolling resistance of the wheelchair is reduced, the efficiency of propulsion increases. With fewer push strokes and less force required to propel the wheelchair itself, fatigue for the user is decreased.Even more important is the aspect of transport and independence; lighter wheelchairs are easier to lift in and out of your vehicle.
