    Dahon: air pump in the seat post

    Hi,

    I've been riding my Dahon Vitesse D5 for a few days and am annoyed by the end of pump coming down to touch the ground, when the seat is raised to the riding height. The problem goes away if I take the seat post off and then reinsert, but without doing this, is there a way to prevent this problem?

    The easiest way I can think of to prevent the pump from falling out is to stick a bit of duct tape over the end. For a more permanent fix, you will probably want to change the seatpost. The pump's locking mechanism has been changed recently, and is now much more secure.

    My parents' LBS switched the seatposts out at no charge, since my mother completely destroyed her pump after it fell out on roughish terrain. I'd suggest talking to your LBS. Hope you figure out a solution!

    Did they change the design and sold me the old one 4 days ago?? The pump came out again today and when I put it back in, I realized that the screw was lost... I understand this is Dahon's first generation pump in the seat post, but it really needs some improvements (even as simple as making the groove deeper).

    I tried to use tape to prevent the pump from falling down, but the tape gets pressed hard against the frame every time the bike is folded/unfolded, and this leaves a lot of mess around the seat post, and the tape lasts only for one or two times of folding. Not a very permanent solution.

    I bought my bike online since I don't even have a local shop that sells Dahon. I've sent an email to Dahon just before creating this thread, so I now hope that they ship the newly redesigned replacement part to me... especially because a few of my friends put orders for their Dahon after I showed mine to them.

    Yes, it sounds like you have the old design. The new one has a spring to help lock the pump in place. I haven't seen one myself, but my parents tell me it is much improved over the original. Hope you can convince Dahon to replace it for free, since I'd consider this a real safety issue.

    I finally received replies from Dahon. I explained to them that my local bike shop doesn't carry anything made by Dahon and I had no other option than buying online. People in my city buy everything from toilet paper to BMW online, so why not Dahon?

    Dahon California rep refused to send any part to me directly, and insisted to ship parts to a bike shop, at my cost, although the problem occured due to imperfect design which they recognized and redesigned.

    So, if anyone buys a new Dahon, my recommendation is to tighten screws for seatpost pump, magnetix latch pieces and other things that are specific to Dahon bikes on regular basis to prevent parts fall off during normal riding. My air pump screw fell off on day 3, magnetix screw and spring (from the rear part) fell on on day 4, of normal light riding after buying this bike. I may use Loctite at those places if the screws become loose again.

    Sorry to hear how Dahon's responding to this, megaptera. Did you agree to have it sent to an LBS?

    No, they said that the parts (that is, a couple of screws and inexpensive small parts) would be supplied with normal charges and they are to be installed at a bike shop, that is, parts price plus the fees at the bike shop. They don't seem to understand that the problem occured within a few days of me buying a brand new 2006 model, and all during normal riding on paved road. Now I wonder if their warranty is of any use. This time the problem was fixable with generic parts from a hardware store, but I got a good sense of what Dahon service is like, so I only hope that the bike won't break or lose parts in the future.

    And the moral of this story is - buy from a company like Downtube that respects its customers....

    Matt52,

    I would not place too much faith in any one company. If you deal with anyone on-line (or even a distantly located bike shop), you run more of the risk of being on your own when something goes wrong with the bike especially soon after purchase. That is why while I may originally purchase the bike (or anything else for that matter) by old-fashioned paper catalog or on-line, I always allow extra funds for that dire predictament that seems to crop up in case the item does not perform as desired, I make sure that I have alot of alternatives available to me before purchase and be flexible as possible. I may ship parts in and have my favorite bike shop perform the needed repairs, I do it myself, or even better I simply upgrade the bike with a part that is not the originally intended part. I bought my first folder, my Dahon, because the warehouse and company offices is only 15 miles away from my residence. I would just bundle up the bike and take it there (with it's receipts of course). Downtube is not as good a choice for me.

    For megaptera,

    If my LBS does not carry the part and/or I have some question, I tend to call Dahon directly, rather than getting lost in the e-mail shuffle. I would suggest that you have Thor help you first. If he can't for some reason, here is their address and phone number in the United States-and make yourself known in a direct matter:

    Dahon California Inc.
    833 Meridian St
    Duarte, CA 91010

    (626) 305-5264

    Call during business hours, Monday-Friday, Pacific Standard Time. In my almost 3 years of owning one of their bikes, I never had a problem that they were never able to solve in a customer to company direct dealings. You should be able to get both the Magnetix and the seat post pump problems looked after.

    For anybody who wants these as add-ons, note that right now the only shipping ones are 33.4mm posts.

    A bit of tape, not over the end of the post, but over the dogs on the pump handle, work pretty well at keeping said handle in place. They add just enough friction that things don't get jostled loose. Think of it as wearing an extra pair of socks inside some shoes that are just a bit too big.
