Note how that picture doesn't show the crank end, which is probably fairly complicated (where is the derailleur?). I don't know how you keep the cable tensioned at both ends so it can drive, but there is no way that will ever be as efficient as a chain drive in all weather conditions.

I found it doing a search for "silent freewheel" i think it was..I was trying to get find a silent 16 tooth bmx freewheel for my single speed(not available yet and will be 75 bucks when it does come out)....its a rowing bike also, which is weird....about this being the past or not a good design, there are some new model motorcycles which use a belt, not a chain...a motorcycle isnt a bike but I wouldnt rule it out..

The belt on a motorcycle would have constant tension because shifting is done before the belt is driven. Figure out how to do that on a bike and you're in business.

There are new and old models that have belts - Harleys famously. However, the advantage in the case of mbikes it that the belt helps reduce transmision snatch, by stretching slightly, a function performed on most mbikes by the rubbers in the cush drive. The belts are not that durable however, and don't tend to appear on higher power bikes.

There are cycles with belt drive already of course - but they tend to be SS folders where the issue is not having a nasty oily chain to mess up your suit trousers.
a single speed would be nice nmishmael

I forget who it is now, but some company will have them out in 2 or so months..75 bucks isnt worth it..there are silent hubs though..they have them for multi-gear bikes and in the 80's, when bmx was king, they made silent bmx hubs(my cousin had one and doesnt know what happend to it, I wouldve maybe used it)...if you find anything let me know...silent single speed would be heaven.
