In today's peaceful, safe and buttoned-down Western world, people go to all sorts of lengths to get themselves the charge of adrenaline they crave so much - whether it's BASE jumping with a wingsuit instead of a parachute or strapping high-powered motors to things not normally associated with motors at all. We need to dice with death and danger, we say, in order to feel alive - and our creativity in coming up with new ways to scare and test ourselves is quite amazing. Take this odd contraption from Hungary - the Standbike SuperBikeBoard is a 250cc scooter with a custom-built rear section. It comes with a seat mounted on a pole, but that's entirely removable so you can take it to a tight track and ride it something like a motorized wakeboard, moving your body around the bike to balance, steer and stabilize it. You'd need thighs of steel to enjoy it for any length of time, because it looks like a very physical riding experience - and with a top speed over 140kmh, you'll want to keep your wits about you.
