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…

Check out this awesome all terrain scooter that is propelled by bouncing. Looks like it would be fun, and it doesn’t look like it would be very hard to use.

Cool off the world around you and get around town. Check out this guy’s homemade propeller driven bicycle.

Nice design for a homemade mountainboard.  If you are wanting to save some money and build your own mountainboard, this might be a good design to follow.  Simple steering system, and a simple overall design.

Here’s a video of a guy explaining how he made his homemade electric skateboard.  Doesn’t sound too complicated.  He made it in the 80’s and it STILL works.

The motor he has on his homemade electric skateboard is a blower motor from a car that is powered by a lawnmower battery.

Check it out.

This solar powered chariot certainly looks goofy, but it is pretty amazing nonetheless.

The three wheeled homemade mountainboard that this guy made looks great, but it doesn’t look like it can turn. I don’t know where he got the frame part of it, but it looks like it was pre-built and all he had to do was put the skateboard deck on it.

Take a look at what happens, it’s pretty funny. Looks painful though.
