Described and claimed herein is a manually operable standing wheelchair that is capable of shifting an occupant from a sitting position to a standing position, and of allowing the occupant to move himself or herself in the sitting position, the standing position, or in any position in between. The manually operable standing wheelchair has a lifting mechanism, with a cable, pulley, and ratchet, which the occupant may manually operate to shift from the sitting position to the standing position. The ratchet is manually operable, and the amount of force required for manually operating the ratchet is adjustable. There is also a lever drive system, comprising adjustable lever drive arms with friction pads adapted for allowing the occupant to move in any position. The present invention optionally includes a set of spring loaded anti-tip wheels that deploy when the manual wheelchair begins to shift from the sitting position to the standing position.
