UNO-Twice as nice
For those of you who are following the two wheeled (tandom) UNO unicycle it has taken a big leap. This months Popular Science has an article about how the UNO now slides one wheel out forward about two feet or so at higher speed for greater frontal stability. I will try to post a pic.

I talked briefly to our local MP3 dealer yesterday, apparently they're selling, and very nicely stable, as you'd expect.

Yeah we had a couple of display demos here on display last quarter at Sam's Club where I work. Altho I haven't seen them on the streets I think they will be popular. No we didn't sell them but offered space for a local distributor. I would think with that short of wheelbase it would turn to sharp thou, unless it goes straight and you lean it to turn with out much turn play.

I don't think short wheelbase means turning too short. It might ALLOW you to turn too sharply at a given speed, where a longer wheelbase might prevent you from making that error but you should always be able to simply turn less. You have to lean into the turns regardless -- or you'll fall over, three wheels or no. The photos I've seen seem to indicate that the wheels displace vertically to allow for lean into turns. But something the dealer said about stability struck me as odd. I can't capture it exactly, something about not being "tippy" or something.

I expect you're right about the "tippy" remark referring to slow speed. I figured a biker would be more interested in high-speed characteristics. I don't think I'd consider a traditional trike to be stable at speed! The *failure* to lean works against it. The dual-front configuration has the advantage of not becoming less stable when you combine braking + turning, though.

No I meant the UNO, being tippy. I would think that as it stretches and brings out that front wheel from parallel to front forward, I would think that is the most dangerous time on it. Having that front wheel with too much play or turn radius would most likely wipe you out at that moment.

I think you're right about the UNO. And it's not just the bike you have to worry about - it's also the road.
