A device for supporting a wheelchair includes a frame and a support system. The first end of the frame is attached to an axle of the wheelchair. The second end of the frame is attached to a wheel for allowing translation of the device over a surface. The support system is coupled to the frame and may be positioned to catch a back of the wheelchair upon reclining of the wheelchair during a wheelie. The position of the support system with respect to the frame is adjustable in order to catch the wheelchair at varying angles of reclining. As the user of a wheelchair develops skill in performing a wheelie, the position of the support system may be moved further away from the wheelchair.
