  1. On a radio show one of my clients was listening to this morning, they had
    people ringing in saying when they first came across automatic gears on
    bikes.
    One caller had them on a 1990 Huffy.

    Coincidentally on tonight's edition of "Beyond Tomorrow" they showed the
    latest Mercedes Benz, which you can get for under $5000. But they claim to
    have the "World's First Automatic Bike"
    Yeah, it was a niceish bike, with some amazing features, but "World's First"
    for Pete's Sake, even HUFFY apparently had them in 1990.

    So just when did the first automatic gears appear for a bike?

    (mind you, that Merc still had some REALLY spiffy features considering it
    wasn't a Mtn Bike)

    Still going strong on the new Giant VT2 and loving it - even in winter

    Most of the "Automatic" bikes I've seen personally have been garbage. The
    (in)famous "AutoBikes" that were around in the mid/late 90s were
    Pacific/Murray/Huffy quality frames with the automatic contraption (weights
    on the back wheels that pulled the mechanism as they spun further and
    further out toward the rim) was connected to a sub-shimano tourney quality
    derailleur. Several years ago some bikes were offered with Shimano Auto-D,
    which has a microprocessor that would cause a 4 speed internal geared hub to
    change based on your wheel speed. It had a button control to override the
    computer and shift. Never had the opportunity to try it out.

    Very easy to use manual shifting trumps automatic systems every time.

  3. I reckon the only upgrade to normal riding would be CVT - constantly
    variable would be an excellent option - all you do is maintain the same
    toque from your legs and the transmission selects the perfect gearing
    ratio to keep you at the max speed without loading your legs any more.
    Works well in SUVs- something like a 15% decrease in fuel consumption.
    I believe they've been fitted to an F1 car too.
