If board sports are your thing, but the current weather and conditions aren't ideal for snowboarding, skateboarding, or surfing, this spring-mounted Gyroboard alternative promises to keep you in shape and let you train all year round.
It's reminiscent of the springy rides you'd find at a playground, but instead of a cartoonish character on top there's a flat deck that spins and bounces around while you ride it. The height of the spring can be adjusted depending on your skill level, as well as how far it can bend to and fro.
You can also limit how easily the $US300 Gyroboard's deck spins, since I suspect that could be the easiest way a rider gets thrown off and injured. And breaking a bone on this thing would probably result in even more injury to an athlete's reputation. [Gyro Enterprises via Gizmag]
