How to build a soapbox cart
Soapbox carts were originally made from boxes in which soap was kept. In earlier times, children simply fixed a soapbox onto a set of old pram wheels, and they had a lot of fun with it. But nowadays, the term means a home-made cart on a low chassis frame. It has no engine or other on‑board power source.
Soapbox carts are usually pushed from behind, but you can also let them roll downhill. You’ll find lots of popular soapbox cart races. There are different ways to steer a soapbox cart – using ropes, steering with your feet, with handles or with a steerable front fork and handlebars from an old bike. A simple soapbox cart is only suitable for low speeds, but it’s a good idea to fit your soapbox cart with brakes.
