Many adventure travellers like to take motorcycles with a backup truck. Even 4 wheel drive trucks get stuck in sand or mud. Today’s invention aims to help out.
These vehicles tend to have V-shaped restraints into which the front wheel of each bike can be rolled and secured.
The back of the truck would have hatches in the floor, so that the rear wheels of say two bikes in parallel could hang down and make contact with the ground (however uneven). The front wheels would remain securely fixed in their restraints.
Someone riding in the back could fire up both bikes and operate their throttles when the truck was in need of some extra traction, turning it briefly into a six wheeled vehicle.
