My son is set on getting a belt drive for the bike he

the exact length for your bike, and if it breaks, it
is very expensive to replace.

So, why?

Clean, quiet, lighter, maintenance free. You'll need to break the frame
somehow (or a split belt. Anyone used one?) and you'll need either
horizontal dropouts or a eccentric bottom bracket, they have quie a bit
of tension.

For a commuter, with a decent frame, I'd go that way now, for just about
any other application I'd stick with a chain.
