chainless bike

[Marian]

Chalo's recent post about a hydraulic bicycle reminded me of an oddity I saw at the local bike shop
about a month ago.

Alas language barriers prevented me from asking a million and a half questions about the oddity in
question and since I had no desire to buy it I wasn't going to bring someone in just so I could ask
questions and leave again.

No chain.

And it had the word CHAINLESS blazoned on it in about 5 places.

There was a bar of some kind that went between the pedals and the back wheel. And that
seemed to be it.

Any idea how they might be powering it?

Should I go back and take a in depth look even if it will annoy them because I have no intention of
buying it?

I wonder if it is like the motorcycles that are shaft driven.

Something like this? http://www.chainless.com/citybikel.html

It is a shaft drive. It has a bevel gears instead of chainrings and sprockets. A shaft connects the
two. It works much like the driveshaft of a shaft drive bicycle. Gear changes are accomplished the
same as on your bike - a shimano Nexus hub.

It's all pretty simple, but adds considerable weight to the bike (despite any claims otherwise).

Shaft drive. Not unusual actually, people have been making "chainless" bikes for a long time, but
they've never caught on. Chains, so far, are the most efficient way of transferring power.

Chains work beter.

C.Q.C.

Exactly like that in fact.
