We built this go kart at my daughters request for her 9th birthday. I thought it would be a useful exercise in project management for her, She drew the original design and I fleshed it out. It is a free wheeler and very fast downhill but heavy to push. We used a broomstick handle to push it up hill as she steered! It is finished with a handmade red leather seat and is constructed from a golf buggy, wheel barrow and a shopping trolley.
