A compact electric assist for everyday manual wheelchairs.

What it is

A removable accessory drive for active manual wheelchair users. Custom motors and a flight compliant battery pack carry you 15 to 20 miles per charge. The whole thing detaches in seconds, so the chair goes back to being light and transportable.

How it works

Snap on for the long ride home. Pull off to charge. The drive bolts to the chair's existing frame without permanent modification — and the controls mount on either side, at any angle, so they fit your grip rather than the other way around.
