New Bike Seat Adjusted En Route by Handle Bar Lever

USING a new bicycle saddle which was recently displayed at the International Exhibition of Inventions in London, cyclists can now raise or lower their seats while on the move. This change of altitude is achieved by simply operating a hand lever attached to the handle bars, as shown in the photo at the right. The lever in turn operates a small pump which supplies compressed air to the cylinder formed by the bicycle frame.

    sounds much more useful as a shock absorber than as a stem height control. i fiddle with my bike a fair bit, but i can’t say i’ve ever wanted or needed to change seat height without braking to a stop first.

    For rental bikes, it might make sense. Although it’s over-engineered, when quick-lock lever would do just fine.

    What a horrible product. Think of all the Benny Hill gags that would have been ruined by this.

    Pretty much the only bikes that benefit from an on-the-fly seat adjustment are mountain bikes.

    I’m just worried that if the pressure fails when you go over a bump you’ll end up with a ten speed supository!

    For mountain biking there are several remote-lever height-adjustable seat posts being used.
    Due to waiting for a clear leader in the field, I have not bought one yet, though I have tried one.
    I can’t say if he uses one, but Repack Rider might share more details if he does. He is likely to have more experience with one of the modern posts. Also, the “Hite-Right” I believe it was, back in the earlier days of mountain bikes.

    Road bike riders don’t need that stuff, but mountain bikers do. I have a couple of the more recent versions on my MTBs. Even the first versions of mountain bikes had “quick release” seatpost binder bolts so riders could make adjustments during a ride, if not “on the fly.” A friend of mine patented a device for the same purpose as in the article in the ’80s, although the new designs work better.

    One of my modern versions has a trigger on the handlebar, the other is released by a lever under the saddle nose. I prefer the latter, since I can switch it between bikes without having to re-attach the cable and trigger. (I have a lot of bikes.) Also, the latter of the two will stop at any point in its travel, while the remotely triggered “Gravity Dropper” only has a high and low setting.

    You get more leg extension for climbing with the saddle raised, and with it lowered you get a lower center of gravity and the ability to put a foot on the ground for crazy descents of the sort from which my “handle” is drawn. I change my saddle height quite often on a ride, depending on how challenging the terrain is.

    Okay, now I have learned something from our mountain bikers. Thanks. Now, the question is, what benefit that gizmo could have offered in -30′s, as there weren’t MTB’s back then?

    I’m surprised that I have never known of bicycle infantries until today. http://videos.mitrasite…

    I believe the Canadian bicycle troops were classified as cavalry.

    @ Toronto – “I believe the Canadian bicycle troops were classified as cavalry.”

    Why not under the Liberals bicycles were classified as armour, and saying “BANG!” was classified as ammunition.

    Would it make sense for a high end retailer to have a bike like this to make it easier to ‘fit’ customers?
