A bike less ordinary? That's what fat bikes were for a few years ago. Today, this somewhat forgotten type of bike is used to build a bike without hubs. If you take a look at the instructions and have a solid dose of handyman skills at the ready, you might be able to do it yourself in no time at all. If that's not extravagant enough for you, you can try building a replica of the hardtail with saw blades instead of wheels with tires.

What happens when an American with the name "Crazy Rocketman" converts a bike? The bike gets a kind of rocket engine with an oversized chimney exhaust that starts to glow during the ride. "Crazy" is the apt description.
