What is this wacky looking bike?! The Velocitech Mountain Machine is arguably one of the most freakish bikes in our Bike Museum. With its mismatched wheel sizes, mega-rise handlebars and loooooong chain stays, it stands out from the more classic mountain bike designs of the '80s.
So what is behind this made-in-Colorado oddity?
Take our latest Vintage Bike Quiz to test your knowledge and learn a little more about this carbon fiber wonder-bike.
