This bicycle was rebuilt from a machine that was used the previous season. I only ended up using a few pieces from the original machine since it functioned in a very different way – the contestants needed to be hit in the face instead of the groin, so the new machine needed to be completely re-designed.
A big challenge was designing the wheel to carry the tennis balls into the tennis ball launcher, since they needed to be metered out one-by-one without binding.
