In some examples, a ski bike includes a frame, a steering mechanism rotatably coupled to the frame, a ski, and a ski retention system. The ski retention system rotatably couples the ski to the frame or the steering mechanism. The ski retention system includes a ski bracket and a fixed member. The ski bracket is rigidly coupled to the ski. The fixed member is rigidly coupled to the frame or the steering mechanism and rotatably coupled to the ski bracket.
