Crazy Bike Inventions

At our next Mobile Social, we’re considering lots of fun bike things to do – [maybe a Bowie v. Prince theme](http://www.momentumplanet.com/blog/glorious/freak-vs-bowie-vs-prince –) or something like riding the craziest bike inventions we can find …

What’s the craziest bike invention you’ve ever seen?

Don’t give away your secret plans to rule bike culture, but maybe you’ve even got a great/crazy idea? And by coincidence, Wired just ran a similar post. Oddly claiming that a CVT was “wacky.”
