Check out this bike called the SpinCycle. 

This is one bike you wouldn’t want to fall off of… not that any sane person would want to fall of any kind of bike, but anyway…
this bike is 10 feet tall.

Monowheel cycles are something different.  With your basic bicycle, riders get “on” and ride, but with a monowheel, the rider gets “in,”  and sits inside of one giant wheel.

While monowheel cycles are definitely something to look at, their is much to be improved in the monowheel world. In the cycle contest, the bicycle still wins over the monowheel.

I’ve never seen a tandem bicycle that has the riders back to back. Kind of plays a trick on the mind. Are they coming or going?

You could bike around on just an average bike… or you could be different and do something like below. Here are a few bikes that people got creative with.  They welded roll bars on so they could do a somersault on their bike, and then keep riding.

Here’s a pocketbike that has a roll bar attached to it….

Here’s a bike that has two roll bars on it to make rolling easier…

Last, but not least, here’s a bike that rolls over… a lot…

Meet the Bike-Yak. It’s a combination of a Kayak and a Bike, and it’s made entirely from parts saved from a landfill. If global warming causes a 10 foot increase in sea level, serious flooding would occur in low lying areas.

The Bike-Yak could be one possible mode of transportation for areas that may become flooded due to global warming.
