From our team’s experience, all you have to do is ask 10 people and you’ll get 10 different answers on how to do it. So really, there is no right way. (But there are definitely better ways – but we’re still not the team to be giving advice on that!)

You could try Googling, which is what we did, and that helped give us ideas. Try Googling for billy cart construction instructions (billy cart is an Australian term). These billy cart instructions were pretty good.

You could also try searching for what past Red Bull Soapbox teams have done. This team, who participated in a Red Bull Soapbox race in 2004 (somewhere in England?), took two bikes and welded them together.

However you plan your cart – make sure it has brakes and steering! Red Bull is a stickler for that…
