SMART DRIVE FOR WHEELCHAIRS
U.S. company Smart-Drive has launched the MX2 wheelchair drive that bolts to any size wheelchair to propel it at varying speeds. Expected to retail for $6 000 (around R84 000), the MX2 is not cheap. The money does buy a 250 W brushless DC motor combined with a 36 Volt, 3,4 Ah battery that is good for 19 km of average range that is durable enough to jump off kerbs. A hill-holder function keeps the chair in place. To speed up, the rider pushes the chair’s wheels faster, and slows them to brake the wheels.
