NuDrive, a lever-drive propulsion accessory for manual wheelchairs that reduces the force needed to self-propel by up to 40%, was recently introduced by Pure Global, Hertfordshire, UK.

Wheelchair users can propel themselves forward and backward, maneuver, and brake by pushing the levers; there is no need to spin the wheel rims by hand.

The ergonomically designed drive units allow users with arthritic or weak hands to self-propel, requiring no finger of hand dexterity. It attaches to most manual wheelchairs with 24-inch, metal-spoked wheels.

The product can be used indoors and outdoors by long-term and occasional wheelchair users who have some degree of strength in both arms, and can help users tackle inclines and difficult or uneven terrains.
