Anyone ride a chainless bike?

I was wondering if anyone rides a chainless bike? Looking around the forums I have seen ads for chainless bikes, Dynamic brand is one. I know I'm really out of the loop, I've never heard of such a thing. But it sounds great. No more getting your clothes caught in the bicycle chain. No more having the chains slip off the sprockets. Chainless probably have their own downsides though as does everything. Can chainless bike riders please tell all?

Sure. I have a friend who makes chainless bikes. They are called "ordinaries".

If you haven't seen this yet, a couple of the commuters have posted reports about shaft-drive bikes: Dynamic shaft drive bike: 1000 mile report

Strida uses a belt. Lots of posts here and elsewhere on the net.

There are bikes with fully and partially enclosed chains.

You should try to ride airfree tires on the road,$65.00 wasted for me.They are decent off road though,but I dont ride off road.

I see once a decade it seems, chainless bikes, elliptical chainrings, and other oddball stuff make a comeback only to die off in a while. Chains may not be perfect, but after centuries of bike design, pretty much there isn't anything better, unless its some specialized function.

chainless bikes - If damage to cloths is your #1 concern go chainless. Chainless also improves reliability and reduces maintenance for those allergic to chain lube. Shaft bikes have automobile style lubrication ports that work with a grease gun, do it right and you won't even see the grease. A bike with a chain case would work as well though. All chains will require replacement after a while, I suspect that shafts will work for at least one human lifetime. The belt on the Strida is a definately working on that bike.

elliptical chainrings - I have one on my fixed gear, I have nothing negative to say about it. The free market has spoken and nobody from consumers to professional riders endorse it. Perhaps with an aging population they might find a market. I think on single speeds they make more sense.

Pretty much there isn't anything better - I suspect hydraulic, and maybe even compressed air, drives might change things. Hydraulic is already successful with brakes. The Nuvinci hub uses 'traction fluid' and is successful, so I think you will see various hydraulic designs. Electric and other boosters might also change things. Automatic transmissions are showing up too.

airfree tires - For short distance commuters who cannot tolerate a flat, otherwise they are inferior.

Dynamic is the only guys to go to for a chainless

I've had a chainless bike for 3 years and use it regularly for commuting, 7 miles each way 3 days per week. I bought mine from Dynamic. They're based in MA near Boston. I've called Dynamic several times over the years with questions and general interest. I even wanted to eba distributor at one time, but they weren't looking for one. But one thing that stands out for me is there service. They don't seem like a big company, because it seems like I talk to the same people a lot. I think I've even talked to the president a few times. They are really great to work with. Friendly, helpful, knowledgeable. They've sent me stuff for no charge if I asked for it. I'd more bikes from them if I needed another bike, just for the service. I've heard there is now another company called Dekra out there too, but my understanding is that they're kind of the cheap Chinese knock-off product. You know they steal good ideas and make it cheaper in some sweatshop in China. Dynamic's bikes are probably more, but I think it's worth it.

How can an elliptical ring work on a fixed gear bike, unless the chain is really, really loose? Can you use a tension device on fixed?
