ABSTRACT:
A twist vehicle includes a vehicle frame, a driving system, and a safety driving arrangement. The driving system includes a transmission member, having an upper portion connected to a steering member, rotatably supported by the vehicle frame. The safety driving arrangement includes a twisting member connected to a lower portion of the transmission member, a driving wheel assembly rotatably connected to two rear side portions of the twisting member, and a front stabilizing wheel rotatably and suspendedly supported at a front portion of the vehicle frame with a safety distance between the safety wheel assembly and the lower portion of said transmission member, so as to prevent the twist vehicle from flipping over when the twist vehicle is moving.
