TrailCart- a Pedal Powered Off-Road ATV

The TrailCart is the world’s first pedal-powered four wheel drive all terrain vehicle. This lightweight vehicle is entirely human powered, giving you all the fun of an ATV with the pain of having to power it yourself. Your leg energy is transferred to all four wheels at once, enabling this vehicle to traverse very rough offroad terrain. The TrailCart is being developed in Germany and is expected to be light enough to be carried on a standard bicycle rack.
