I saw one of these last night and talked to the owner, this thing is bad ass shit. Sounded like a phukin Harley pulling into the gas station. I can fit this in the back of the Burb with the 3rd row seat up. It's the size of a mini-bike, with big bike features, street legal. After doing some researching these things have been around a few years, but it's the first time I heard of them or seen one in action. Really cool.
