Brompton Bikes

I've been a fan of Brompton bicycles for some time, but I've never actually owned one. The company is famous for their folding bicycles and first filed for a patent on their mechanism back in 1979. The design has been iterated on somewhat since, but the fundamentals remain the same.

Over a weekend I modelled up my version of the bike and played around with rigging and animating the mechanism in the hopes of better understanding it.
