Something truly special can often be created by combining two great things, and heck, even if one of them is just pretzels you still have some sick-ass Combos. For a truly impressive hybrid, check out the MXB Shocker.
Looking like a machine the X-Games couldn't handle, the Shocker's a rugged "Motocrossboard" -- basically the mutant offspring of a snowboard and a scooter -- engineered by a boarding enthusiast for maximum dry land maneuverability through simple snowboard-style shifting of your weight between your heels and toes, or piggies, if you're getting technical. (Haha, piggies aren't technical!) The ride's crafted from 4130 chromoly steel tubing and equipped with fully adjustable suspension, disc brakes, a rechargeable battery, and a hand-held throttle/brake to control speed, which ranges from 18 to 35mph depending on terrain and the rider's size & ability, metrics often used to determine how much someone will want to ride you. There're also optional add-ons like a speedometer, a chrome frame, extra battery power, and training wheels, although anyone capable of riding such a beast ought to be able to handle their tequila straight.
For the truly daring there's the Moto XC model, with an optional CVT transmission that can reach top speeds as high as 60mph -- just make sure you can handle that action, lest the pretzel ends up being you.
