    folding handlebar designs

    Are there any folding handlebar designs that don't flop when folded? Something rigid, perhaps with a hinge?

    I have this handlebar which I tracked down to a German company and they were very gracious and sent them to me. I am located in Canada. I placed the bars on my Mariner 26 and now it folds without the need to remove the handlebar. The name of the manufacturer that supply pacy is Willkommen bei Humpert. I have recently tried this web site and it was down but I still have my e mail link if you are interested. They were an expensive purchase but worth while.

    Thanks for the links, very handy :-)

    is much faster than the bars on my Strida, but probably a tad more expensive ;-)

    Yeah, nice right? Looks heavy though.

    Yes, & yes.

    is maybe lighter, & could for example, extend the handlebar reach on a Strida for those needing a longer reach?


    I was wondering if I could incorporate some kind of lock via the folded bars for those rare occasions when I can't take the bike inside with me.

    Looks like some of the folding handlebars are patented. The threaded ring looks like it would be very positive, not working loose during rides

    The Strida handlebar locks into position when folded; to fold the bar you release a QR lever, pull the bars out of the stem a little bit, fold them back, and lock the QR again. The bars pivot on little studs, which is kinda like a hinge. It's a pretty good design; the bar is very stiff when riding, and quite out-of-the-way when folded. It's rather similar to what you see on scooters like the razor, but much beefier.

    The handlebars on the razor have two little brass spring buttons that would allow you to disconnect the handlebars completely if it weren't for the fact that the bars are tied together, right?

    Well, my Carryme has similar handlebars, except that they have two squeeze clamps in addition to the brass spring buttons. Here is a picture of the folded handlebars:

    The handlebars are perfectly rigid when unfolded, but when folded they just flop around (they're hanging by elastic). This isn't really a problem, per say, but if they were rigid while folded then it would solve a number of other problems for me. See this picture:

    The handlebars aren't folded here, but you can imagine what it would look like if the handlebars were folded down with the seat in between them. Handlebars which are rigid while folded would solve the following problems:
    1. Although dragging the bike by the seat works fine, if you pick the bike up by the seat then the weight of the bike makes the seatpost pivot (ie the bike starts to unfold). If the seat were somehow stuck to the headset then this wouldn't be a problem. Handlebars that fold rigid would squeeze the seat and hold it in place like two little arms.
    2. The handlebars are the tallest point of the bike. Therefore, they would be a good place to grab the folded bike (especially when pulling the bike by the larger rear wheel instead of the trolley wheels) except for the fact that the headset still rotates freely while the bike is folded. I've thought about ways to try to lock the steering by modifying the headset, but it would probably be difficult to modify and would only add extra steps to folding the bike. However, if the handlebars folded rigid then they would, again, squeeze the seat and hold the steering in place.
    3. No flopping handlebars is a benefit in itself. Besides, the double squeeze clamps on the present handlebars look heavy.

    I've heard that the Strida handlebars flop while folded, but you say they lock while folded. Compatibility notwithstanding, do you think they are rigid enough for my needs?

    I've read this twice & am unsure what you mean.

    Strida bars are rigid when the bike is *un*folded, ie. ready to ride.

    The bars on 2 Stridas I'm familiar with just hang down loosely when the bike is folded, but it's no problem as they can be tied together simply using the bar end loops.

    I sometimes just unlatch 1/2 a bar when I'm nipping into the very small corner shop :-)

    Some of the designs on that German site have just 1 (un)lock point, so should be faster to (un)fold.


    Makeinu, it looks like the Strida central "latch" does the equivalent of the clamp on the Carryme.

    Try humpert.com it's working fine for me.

    The name of the company is Humpert. "Willkommen bei" means "Welcome to".

    If you want me to translate anything from their website that's not in English already let me know...
