Default Belt Drives

Sooo...why don't we see more belt drives? Maintenance free, tough as
tarmac, used on motorcycles and cars so proven technology.


Same reason you don't see many on motorcycles: less efficient than
a chain. But on a m/cycle you can get over a lot of the problem by
just putting in a bigger engine, which doesn't apply to bikes in
the same way...

Same with shaft drive. They're there and you can buy them, and you
have the same pros/cons (though both to a greater extent with a
shaft): cleaner and less maintenance, but sucks up more power and
limits your choice of final drive gear.

Also the case that you can aovid a lot of ther mess and maintenance
of a chain drive, at least with hub of single speed gears, by just
enclosing it, which does add a little weight but doesn't compromise
the efficiency (and by reducing the amount of chain wear from road
clag may actually improve matters over the longer term).
