    Is your folder noisy or silent?

    Hi all,

    reading about whistling and creaking birdies made me wonder if there are very noisy folders and others that tend to keep quiet. What sounds do your folding bikes produce, can you track it down and stop it - or does it belong to the bike no matter what you do and do you perhaps like it (some love the sound of a Speedhub)?
    My brommi sounds: "rattle rattle rattle" especially when going over rough terrain. I could not figure out what it is so far. I suppose it derives from the roller wheels and the chaintensioner or the mudguards.
    My Carryme has always, not only when coasting, a clear but full hub-clicking "drrrrrrrrrrrr"- and is otherwise absolutely quiet.

    Also can you say something about the components perhaps. Like some tires for example the Marathon supreme:"sing".

    The merc is silent.

    In its early days I did have to tighten up one of the crank arms to get rid of an annoying creek and I took off the little roller wheels. Nothing else makes a noise.

    My bikes are relatively silent. One time I had a pedal bearing begin to go. It took me forever to find it. Occasionally, the Bike Friday makes a creaking sound. I figure that it is time to lube the rear hinge.

    It took me a long time to track down the source of the squeaking on my Vitesse and in retrospect it originated from the most obvious area, the frame hinge contact area. No more squeaks, but my Sturmey Archer XRF5 hub is noisy and stupidly inefficient.

    Mine are noisy, but keep in mind that at 230 lbs. I'm at, or just above, the weight limit. In order to reduce noise I need to make sure everything is tightened properly and lubed properly, but I still end up with squeaks and groans. I doubt I could ever eliminate them entirely.

    No creaks or groans under my fully dressed 205-207 lbs. on either the Boardwalk S1 or the NWT.

    Initially I had quite a bit of cable "chatter" on my NWT. Some judicious use of black zip-ties eliminated most of it.

    Went through the aforementioned clicking sound on the S1 last year, but my bad pedal fell apart within a day or two spilling the beans on what the problem was.

    Mostly silent. The drivetrains tend to be noisiest. But I tend to worry about noise till I find it. The Birdy mudguards tend to make a bit of noise over rough terrain.

    I also investigate new noises immediately out of concern for frame cracks or the folding mechanism developing play. Nothing of consequence on my Swift so far. In fact the noisiest bit has been my Brooks saddle. I found several good remedies for that in the other forums and its been pretty quiet since. The only other sounds comes from the drivetrain, mostly in 1st and 2nd gear. Think those cogs are still not broken in since I rarely use them.

    Downtube 8H. There is a very quiet squeek while pushing the bike slowly. I think it is the rubber cap that covers the axil bearings on the front wheel. Yesterday while standing up to make it up the last bit of a steep hill I heard lots of complaining from somewhere. A little unnerving but nothing blew up.

    My Swift has a resonance in the frame that I haven't heard before--kind of a "ting!" when cables tap or buzz against it. I sort of like that it has a signature pitch, but it occasionally gets annoying, so I ziptie as needed.

    However, there are two sounds I love about it. One's the clicky pawl and ratchet whir when it coasts, and the other is a smart little clang when shifting into some gears.

    My Dahon Matrix was silent for the first couple of months, but the fold and seatpost were pretty frustrating sources of noise after that. I had to clean them thoroughly and often.

    My CarryMe makes noise too. Unlike the OP, mine does whrrrrr sound when I'm riding and klank sound when I hit some bumps. The klank sound really perplexed me until I found out the sound came from the roller wheel behind the luggage carrier.

    My Sturmey Archer hub has a fairly loud whrrrr sound but it is meant to be normal, I think. Some creaks here and there when I pedal hard but not much.

    My Strida 5 has a silent ride, but really noisy brakes. You can hear those suckers whining from a ways off. I need to take it in and see if the shop can do anything about it. No problem in terms of funtionality, just annoying.

    macross, probably our CarryMes sound the same? what you call "whrrrrr" is probably what I meant by "drrrrrrrrr"? The clicking of the hub that is, its a little too loud for my taste but I very much like the tone of it.
    The "klank" I never heard but I changed the little roller wheels right away to some grind skate wheels with better bearings.

    I think you're right. My description of the sound is probably identical to yours.

    And I will follow your path and change my original roller wheel with a better one. Thanks.

    I have been surprised at how silent both my DT IX and BF NWT have been. It has been a bit too easy to sneak up on other riders and pedestrians. They both occasionally make a bit of noise, but very little to speak of.

    While riding the DT recently I noticed what I thought were birds nearby making chirping sounds. Since it isn't the season for that kind of behavior, it caught my attention. Being a fan of nature I was enjoying hearing them and wondering what they were up to, this late in the season. I was enjoying hearing them, but something didn't seem right. It began to sound repetitive and varied little in volume.

    The next day I noticed that it was happening again, but in very unlikely locations. It was also a fleeting sound, and erratic. By paying close attention I noticed that I only heard it when riding next to a solid surface, like a parked car or the wall of a building. Finally it dawned on me that it might be the bike(or my knees, God forbid!). Doh! It was either that or I had birds following me around on my bike.

    I took a while but I finally found the culprit. A rack support I had made had lost its rubber protective strip and was rubbing away at the powdercoating, while making subtle, distant sounding "bird calls". Mystery solved, and I now have a quiet DT again. Sure miss those birds, though!

    My Mini is mostly silent, but not perfectly so. Still, when it makes a noise I don't understand, I take the time to figure out what it is and, usually, correct the problem. My chain has one or two places where it ticks every time it goes around, and I have so far failed to correct that one. Also, when I pick the back wheel up off the ground and spin it, it sounds really terrible, like the ball bearings are made of irregularly shaped stones; but it rides smoothly, so I guess it's okay.

    My Brooks Champion Flyer on my Pocket Llama creaks sometimes but not always. On another bike I once spend a long time trying to track down a clicking sound in my crankset that turned out to be the end of my shoelace hitting the crankarm every revolution.
    Relax, it's a bike ride.

    My Tank Micro 16 is silent.
    My Tote Cycle has a clicking sound from the rear hub when I coast. I think all Sturmey Archer 3 speed hubs make that noise when coasting.
    I've never heard a bike moan, creak, pop, or groan ... the bike rider, maybe, (myself included) but not the bike itself.

    Good to meet you on the path today. Forgot to mention that in the Winter, it becomes feasible to turn off the path at Peter Stuyvesant High School and to stick to the water on your way to work. Give it a try.
