Belt Drive
Has anyone ever seen a bicycle using a belt drive? Or have more information on it? https://www.sec2u.com.tw/SEC-BELTRANS.htm
It has its advantages, no need to oil, no maintence, great at absorbing shock
I doubt a person could exert enough force to tear the belt. I bet in the future that will be the norm, just like motorcycles today.

Ehh....I dunno about going brakeless and fixed with it. Maybe single speed, but I think that chains are here to stay

Do you really want to have to invest in a "belt collection" in order to change cog sizes?

I've seen folding bikes that use belt drive and there are aftermarket belt drive systems. In general, belt drive compares favorably in terms of weight and strength with chain drives, that's why they're used on motorcycles. However, I can't imagine how one would use a derailleur setup with one, so it would require a wholesale shift to fixed/ss or internally geared hubs.
Bicycling Science covers them among other alternative drive technologies. I'll try to remember to look it up when I get home.

"The future of bikes" is ugly as crap.
Besides, I don't know if I want a drivetrain that will dry rot.

Here's drive system I was talking about. I thought it was retail, but it turns out it's an Izzy Urieli custom job. https://www.ihpva.org/Builders/Izzy/ and https://www.ent.ohiou.edu/~urieli/ Izzy's built a few different belt drive bikes.

I'm sure WorldWind knows, but to be clear, real bike shaft drive is old as the hills. It's less efficient than a chain drive, though.
Old: https://www.firstflightbikes.com/shaft.jpg
New: https://www.chainlessbikecompany.co.u...tyle-photo.jpg
(incidentally, the latter was suggested by a friend after I chopped off the end of a finger working on my fix this spring
)

The main issue with belt drive (particularly converting normal bikes) is getting the thing on there in the first place. You can open up a belt like you can a chain, and as anyone who's tried to strip a frame without a chain tool will know, the chainstay is kinda in the way.

See wasn’t that better, even pictures. Show me one that can shift gears.
No stretching, that would rob power. No slipping, that would steal power. Must be able to open so you can get it on the bike.
If you think about it, a belt drive with all the faults removed is …. Is … why by golly it’s a chain.

WorldWind, you obviously didn't look at Izzy's bikes, unless you're talking about the shaft drive. In that case, you could use an internally geared hub in exactly the same fashion.
Belts come off just fine--otherwise they would suck for foldables, there's no more slippage than with a chain--it's a toothed belt, and stretch is all relative--it stretches slightly more than a chain which makes it less desireable for race applications but perfectly suitable for other purposes.
The fact is, many motorcycle manufacturers have moved to belt drives for all the reasons mentioned above and there are already mass-produced bicycles that use belt drives without a problem. It's a perfectly workable solution even if it's not what I would personally choose.

Hey kids, I'm not going to tell you about the tremendous superiority of belts, because I work for a belt manufacturer and that would be unethical.
But hey, I wanna make such a belt drive bike for myself. I hear they used to produce mountain frames where the chainstay goes way up in the air as some rediculous way of avoiding chain slap... anybody know what models did this?

Belt drives are only used on fat asssed poseur motorcycles. No race bikes need apply for the added weight and increased stretch.
You really want to go that route on a fixie?
