Anyone else seen, or better yet road one of these Shaft Drive chainless bikes? I am very interested in them, so I wanted to know what you all think about them?

Never seen or ridden one, but chainless bikes have been around for over 100 years, and they have never gained a real foothold in the market. I don't see why this particular one would be any different. It doesn't appear to have improved in any meaningful way on the Columbia chainless bikes of the late 19 century.

The supposed benefits cited by the manufacturer sound somewhat ridiculous to me: you won't get grease all over yourself and won't lose a finger. Are they trying to say this is the perfect bicycle for someone who is prone to clumsiness?

By their own admission it may not be more efficient compared to a well-maintained chain system and they offer no science to support their claim so the numbers are meaningless anyway.

If your drivetrain parts break or wear out, can they supply them quickly? How much are the parts? E-mail them or call their 800 number and see how long it takes to get someone who can actually answer these questions.

I can't knock the ride of bike because I've never ridden one, but chains are easy to come by, and so are pants.
