A wheelchair comprises a main frame (10) carrying front wheels (18), a battery pack (22), and a foot rest assembly (32, 34). The wheelchair is driven by means of a pair of rear wheel units each comprising a drive motor (24) and a rear wheel (20) mounted on a sub frame (42). Each rear wheel unit is removable, as a unit, by releasing fastenings (42,46) which secure the sub frame to rearwardly projecting extensions (66,68) of the wheelchair main frame. Preferably, kerb climbers are mounted on the foot rest assembly whereby the kerb climbers and foot rest assembly can be removed from the main frame as a unit. The kerb climbers are preferably pivotally mounted on the support members (34) and may be located either in a use configuration or in a storage configuration in which the kerb climbers do not extend forwardly beyond the pivotal connections with the support members (34). <IMAGE> |
