I built this five-passenger bike by cutting apart and welding together the parts from three tandem bikes, and adding a bit of black gas piping where I needed straight tubing. It actually worked too, and I was able to take it for some wobbly rides in the studio! (Though the rear seat was responsible for shifting gears, since my cables weren’t long enough.)
Inflatable hot water bottles were added to make exploding seats (by Jason Singleton and Jessie Voris, I think)
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.
This tandem bicycle was modified so that the rider in back would be given a wedgie when the rider in front pedaled. I welded the bike to stands so that it would stay stationary, and modified the freewheel into a pulley so that the rope would be wound up to produce a wedgie.
