Belt drive bikes?
Hello,
The bike in this video[www.trekbikes.com/us/en/bikes/urban/soho/soho/] has a belt drive. This belt drive is completely new to me. Are you folks familiar with this? Do you know any other bikes that have the same thing? How is its performance? It looks cheap, flimsy, and easily breakable to me.I think I'll stick with the old metal chain! Cullen |

The drive belt is way over-spec for the job. *It should pretty much last forever. *A chain needs replacing every few thousand kilometres. I've seen these in the shops, and a few years ago saw a custom-made flat-bar tourer with a belt driving a Rohloff gear hub. *A little less mechanical efficiency than a chain and derailleur, but clean and ultra-reliable. *I'd consider this setup for my next commuter, for sure.. The drawbacks, while not necessarily "deal breakers", are nagging horrors: 1) separable right-hand "chain" stay 2) limited range of ratios (since you can't add or subtract links to the belt) 3) availability of replacement belts &/or pulleys (I guess if these become popular enough we can talk of "belt- wheels" ad nausuem) 4) belts often need significant pretension to transmit. I suppose the notches are to help with that, but once the rubber ages a bit, and those notches start shedding like the mange, what do you do? 5) fouling from sticks, plastic bags, squirrels (I know a chain isn't a magical cure for this, but my fixed-gear has rather blithely eaten a few sticks without harm. I'm a bit curious as to how the belt performs in a FOD heavy environment) |

Belt drive will catch hold when it becomes reasonably cost-competitive with chain, and not until then. As it is, you can buy an pretty decent chain-drive bike for just the cost of a belt and two belt sprockets. That's a recipe for failure-- completely predictable failure. Chalo |
