pedals, for starters
I shipped my bike recently and had a bike shop put it together, which I'm not qualified to do. I took it for a ride recently and all went well until I parked it and secured it for 10 or 15 minutes while I got a soft drink. When I returned, I didn't notice anything wrong until I started riding it. I eventually figured out that the pedal was bent out of position. Shortly afterwards, it fell off. It cost me almost 40 dollars to have it fixed because not only was the pedal screwed up but the threads on the thing (?) it fits into were ruined so the thing had to be replaced also. When I picked up the bike at the shop and rode away, at first the pedal felt funny, as it had when it started going bad, but that feeling quickly went away and I think it is probably ok. I have no idea how to check it, though. It's tempting to think that the damage to the pedal was the result of recreational vandalism or that someone simply didn't like having bicycles parked in that spot or that someone might have walked by with a handtruck and hit the pedal, but upon reflection it could just as easily be the result of it having been improperly placed when the first bike shop put it back together. There is another possibility too: I have to bring it in and out of an apartment and there are a lot of opportunities for the pedals to bang against doors on the way in and out of the building, so maybe that eventually did in the pedal. I'm trying to figure out how to prepare better for future problems like this. One thing would be to learn more about repairs so that I can simply scavenge parts and do repairs myself. I don't know if this is a particularly advanced repair job for someone just starting out. If so, having spare parts to bring to a bike shop with the bike might knock my costs down to just the labor of installing it. Another idea that occurs to me is to install pedals that can be folded up when they aren't being used, so that they stick out less and don't bump into things. I don't know if such pedals are available. Alternatively, what would be wrong with pedals that consist of a round bar and which don't rotate and which are one piece with the aforementioned thing that pedals normally attach to? That way it is less likely that the pedal can be damaged and that it and the thing will needed to be replaced. As one pedals, the same kind of surface will always be presented to the shoe. If it is desirable to have the foot fit inside something, as I've seen on some bikes, it can be attached to the bar and rotate around the bar. That would probably be a lot cheaper to replace if anything happened to it. I talked to one bicyclist I passed on the street and asked him if his bike has ever sustained any damage while being parked and he said not really even after a year or so of parking it. So I think that even if it was vandalism, which is in doubt, it was exceptional and I should probably continue to feel comfortable parking my bike. At the same time, I have to be prepared occasionally to make significant repairs in the bike, so I think I need to start collecting spare parts and tools. The bike shop didn't seem to sell the tools that, according to Rob van der Plas' book, "Bicycle repair, step by step", they would have had to use to make this particular repair. I'm not sure where I would get them and how to know that they were of good quality. Maybe it isn't a good assumption, but I'm inclined to think that a repair that needs to be done once is likely to be needed again sooner than one that has never needed to be done.

Sounds like the shop didn't tighten them, maybe they hand tightened them and
didn't go back with the wrench. I swap pedals on my bikes all the time. And carry my bike up and down from the 3rd floor and through the halls every day. Never had that happen to me.

Wheels, deraillers, cables and even frames are easier targets. I did the exact same thing. When I installed my first pair of SPDs I crossthreaded a pedal. Discovered it a mile down the road when the pedal got lopsided. Ended up buying a new crankarm on that one. I'm much more careful now... :-) |

Hello, Allan. and hit the pedal, but upon reflection it could just as easily be the result of it having been improperly placed when the first bike shop put it back together. That is much more likely. If the pedal is not tightened, it can work loose with results as you described. Your average vandal would not have the tool needed to loosen a properly-tightened pedal, which will probably require considerable torque. Such a vandal would more likely kick your spokes in. I'm trying to figure out how to prepare better for future problems like this. One thing would be to learn more about repairs so that I can simply scavenge parts and do repairs myself. I don't know if this is a particularly advanced repair job for someone just starting out. Not really. It does help to have general comfort with tools and mechanical things, but beyond that the specifics are pretty straightforward. Another idea that occurs to me is to install pedals that can be folded up when they aren't being used, so that they stick out less and don't bump into things. I don't know if such pedals are available. Some folding bikes have such pedals, but I don't think they are in common use. -- David L.

I can't imagine a pedal FALLING OFF unless it had not been tightened properly. It's evidently not that hard to cross-thread pedals. I picked up an abandoned Schwinn Frontier a couple of years ago that had a cross-threaded pedal (interestingly enough, the right pedal). The irritation from this pedal may have been one cause of the abandonment. ...someone might have walked by with a handtruck and hit the pedal, ...[or] a lot of opportunities for the pedals to bang against doors on the way in and out of the building The pedal could have been bent by an impact (I've bent a pedal by scraping a pedal on the ground while rounding a turn, for example). But it wouldn't fall off. There are so many easier ways to vandalize a bike that the vandalism theory doesn't seem very likely to me. I don't know if this is a particularly advanced repair job for someone just starting out. It's easy. The main thing to remember is that THE LEFT PEDAL HAS REVERSE THREADS (i.e. lefty-tighty, righty-loosy). Also: Tighten it fully tight, but don't go overboard. Grease the threads when you put the pedal on, so it will not rust into the crankarm. having spare parts to bring to a bike shop with the bike might knock my costs down to just the labor of installing it. In my experience, bike shops don't like this much. If you are a regular customer and are asking for something that involves special tools (e.g. swap two rear gear clusters) then OK; otherwise you won't get much enthusiasm. The bike shop didn't seem to sell the tools that, according to Rob van der Plas' book, "Bicycle repair, step by step", they would have had to use to make this particular repair. To swap pedals, a simple wrench is sufficient. |
