A platform for a wheelchair (50) and sitting occupant which allows the occupant to move across an ice covered surface for exercise and enjoyment. The wheelchair wheels (60) contact two pairs of rollers (5, 9) within a slot (3) formed by two pairs of positioning rails of a frame (1). The rollers connect to a series of gear wheels (13, 15, 19, 23) which transmit the wheelchair wheels motions to drive roller wheels (25) located underneath the platform. The drive roller wheels (25) contain studs or cleats (29) to grip the ice surface. The trailing edge of the supporting platform is elevated off of the ice surface by a pivot wheel (33).
