I don't know why, but I am desperate to own one of these! Imagine the gravel you could destroy on a three wheel gravel crusher! Talk about a frame bag makers delight (AMY.) You could stash bags all over the place on one of these things. And if a person rode, say, until they fell asleep on their bike (Mike!) there would be no problem with falling off. You wouldn't even have to take the rear wheels off to fix a flat or change tires. Now that would be worth the price of admission. Fenders, well they're just cool on a road-type bike, 3 fenders... "Well, it's one louder, isn't it?"
