Abstract
A wheelchair according to one embodiment includes a frame, a pair of drive wheels operatively coupled to the frame, a drive operatively coupled to each drive wheel, and a pair of anti-tip assemblies. Each anti-tip assembly includes a first member, a second member pivotally coupled to the first member at a joint that defines a pivot axis, an anti-tip wheel rotatably coupled to the second member, and a locking mechanism. The second member is capable of pivoting about the pivot axis between an extended position and a collapsed position. The locking mechanism is configured to selectively lock the second member in the extended position.
