The future doesn't have to degenerate into a Soylent Green type of dystopia for people to realize the value in recyclable transportation. That's right-instead of cars and bikes that take forever to breakdown, maybe it makes sense to build them out of stuff that can dissolve before the next Ice Age.
The bike above is only $29 and can support a 300 pound rider. Would you ride one? Just hope it doesn't rain
