A wheelchair includes a seat mounted on a frame supported on two wheels only. The wheels are mounted one in front of the other so that in use a first of the wheels tends to follow in the track of the second wheel. Handle means are provided by which an attendant can propel the wheelchair and maintain it upright. The size of the wheels and the location of the seat lengthwise between the two wheels ensures a low center of gravity and easy management by the attendant. Preferably the foremost of the two wheels acts as a castor wheel.
