摘要：
The present disclosure describes devices and systems that can be integrated with a foldable, manual wheelchair to convert the wheelchair into a hybrid chair capable of both manual operation and motor-powered operation. A wheelchair powering device includes a motor that is operatively coupled to a roller member so that rotation of the motor shaft causes rotation of the roller member. The roller member may be engaged against a tire of the wheelchair so that rotation of the roller member causes rotation of the tire via friction between the roller member and tire.
