Zoomla folding bike concept

Another from Erik Stoddard, this actually looks pretty slick. Steering via skateboard-esque tilting, propulsion with levers and sliding footpads (to change leverage and simulate gearing).

Tankboard

The DTV Shredder is a rugged skateboard-with-handle, designed for off-road use by the military:

Freerider Skatecycle

Kyle found the Brooklyn Workshop Freerider Skatecycle, a real version of the ObliqO prototype I lusted after a while back:





Just $150 at their online store.

Razor Sole Skate

Razor is back with a new skate concept--the Sole Skate. A one (and a quarter) footed skateboard, it is compact enough to fit on or in a bag for travel.



Inexplicably marketed at the stunt skateboarder, this would be interesting in and around workplaces.

Hubless wheeled skateboard

And for once, there's a benefit! To ride the ObliqO you put one foot inside each wheel and do a scissor motion with your legs; kind of like the RipStik or the Snakeboards from the 80s.

Hoverboard on vert ramp

This would probably look pretty dorky if he wasn't riding it on a vert ramp! Then the zero friction is probably awesome (not sure what happens when your air cushion spills over the top, though...)

In stock for $14,000

Max Skate Bike

Combine the worst parts of skateboards and bicycles and what do you get? The Max Skate Bike!





Another, more modern take:

Stowboard folding skateboard

Scarpar off-road powerboard

Scarpar off-road powerboard. A snowmobile for your feet! Engadget likes it!

Board-skate Xlider

Board-skate Xlider - Tasem Co., Ltd.

Who needs the middle part of a skateboard anyway?

"Utilizing high-friction rubber, the rider is completely secure and safe, even though they are not strapped in." Well, thank goodness for that!

Wheelman Motorized Skateboard

Gadgets: Wheelman Motorized Skateboard

Fantastically-dangerous way to get around...but pretty elegant too.

Pumpboard

Clearly a concept because it uses spokeless wheels (is anybody working on this technology? every industrial designer is apparently craving to use it), this skateboard is inflatable and rolls up for portability. Must be pretty light!

Powered skateboard with bindings

"'Skate' from Matteo Gentile adds an electric motor to a stripped down hybrid of a skateboard and snowboard bindings, creating something altogether different, dangerous and cool. Ostensibly created for regular transport and short commutes, I think we all know what was going through Matteo’s mind when he sketched this bad boy out."
