There was a guy at a marina where I kept my boat that had an aluminum single speed bike with a belt drive. It apparently worked great, he parked it on the dock next to his boat and it was there for years and years with no apparent maintenance what so ever. A chain drive would have been rusted itself into one solid chunk in that period :-) Was that the Bridgestone OPC14 with V Belt drive? I sold those . Nicely done, great price, no complaints. Wild looking thing: https://sheldonbrown.com/bridgestone...e-opc-14b.html It says that little bike weighed 29 pounds! I know the belt drive did not add that much. Did the bell and basket add all the extra tonnage? |

I don't know. I did noticed that it was a "notched" Vee belt although I don't think that the pulleys were notched and it was not a fixie and had brakes fore and aft. -- cheers, John B. |

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. |

Imagine it would be much heavier and complicated, they have been tried and used on MTB but don’t seem to have been cracked, I think generally the extra weight/cost though a E-MTB would mitigate that? Given a choice I’d love a belt drive bike for the commute as I clock up fairly respectable distances per day which does chew though the drive chain. Roger Merriman |

Have to say a belt ticks far more boxes that a shaft. If I were doing it all over again, a belt would be the answer, you don't even have to enclose it. |

Motorcycle manufacturers have figured it out, most of all BMW. That company should also build MTB, they know how it's done. Weight doesn't always matter, especially not for many MTB riders. We just want less wear and most importanly not have to clean and lube the chain every 50 miles. It often takes the bicycle industry decades longer to figure something out. Such as decent heavy-duty rack space on FS MTB and central-battery powered lighting where, no surprise, I had to build it all myself. Beats me why one still cannot buy this: http://www.analogconsultants.com/ng/bike/Muddy5.JPG It's lasted many thousand hard miles now which included heavy loads. Yeah, that bike is heavy but it never breaks down anymore. Given a choice I’d love a belt drive bike for the commute as I clock up fairly respectable distances per day which does chew though the drive chain. I'd be careful ... https://www.thelocal.se/20180524/ike...-lead-to-falls -- Regards, Joerg http://www.analogconsultants.com/ |

Maybe weight doesn't matter in your world but it sure does to a LOT of other MTB users. I keep telling you Joerg; your best bet to get the durability that you say YOU need is to buy a small gasoline powered dirt motorcycle and convert it to pedal power. After all, weight doesn't matter to you. Cheers |

I keep telling you Joerg; your best bet to get the durability that you say YOU need is to buy a small gasoline powered dirt motorcycle and convert it to pedal power. After all, weight doesn't matter to you. Within reason, of course. There are people who rather ride a bicycle that weighs 10lbs more than customary but in contrast to others they generally arrive at their destinations on time, due to a lack of breakdowns. I happen to be one of those. The only times during the last years (!) that I didn't arrive on time were when I assisted others during repairs. Because they didn't have thorn-resistant tubes et cetera. -- Regards, Joerg http://www.analogconsultants.com/ |
