Its deffinatly got a market. handicap people who dont have two legs, or someone with a bad foot or leg would deff get it due to not having to suport the weight. plus the added safty you would have with tire blow outs i would think would have the lawyer-type guys who just wanna cruise on the beach worry free buying them. cause as we all kno you loose tracktion on 2 wheels, and your Fucked 90% of the time, you loose tracktion on that and it would be like hydro plaining a car. not fun but atleast your not rolling down the cement.
