just curious, how would the belt close on itself?
^^ hahaha... a toothed belt slipping? not likely.C'mon.... it's a pedal powered bike, not a seven second door slammer.Belt drives are common on high powered choppers, and superchargers... Late model hi-tech engines run timing/cam belts now instead of the older less efficient chains.A belt requires no lube, is a lot quieter, cleaner... and the average timing belt in a car (under alot more stress) will last for around 80,000 kilometres (50,000 miles).The way to go I think is with shaft drive set-ups. Like the late BMW motorcycles. Or like the tailshaft on any rear wheel driven car. There would be no need for a chain/belt/sprocket etc... Plus it would add a huge amount or rigidity to the back end, possibly enough to eliminate one complete rear chainstay on that side of the bike.Just thinking out loud...
