The Sky Cycle. Take one rickety looking pedal cart thing, attach it to an impossibly high and very thin track, strap people into it with a single seat belt and you’ve got the recipe for what looks like the worst experience on earth. And lets not talk about wind, shall we? PS. I suspect the pretty pink baskets on the handlebars are to catch your heart when it literally thumps its way out of your chest. [Thanks Daniel]
