    cabling issues on folding bikes ... history?

    Someone just passed this to me ... http://velonews.com/article/72308

    It is an electric Dura-Ace derailer system. While it still has wires, it still has obvious perks for folding bikes that typically experience issues with running cables. The brakes, however, are still powered by old-fashioned hand power.

    Dunno... there is something about bicycles being completely human-powered that appeals to me... It seems this is mostly a Shimano stunt to continue on the never-ending path of upgrades... and obsolescence...

    FWIW.......Mavic also made one back in the day. They pull serious cash on ebay. If gears are wanted without cables what about an old kickback 2 speed? Those are pretty cool.........And some were darn near indestructable.

    Two, Zap and Mektronic, both failures. Campag are also trying to get an electronic system up and running.

    Yep ... for regular bikes, I don't see much of a point. That is, how much could shifting really be improved with an electric motor? Folding bikes is another issue.

    Would it be nice to get a front derailer on your Swift Folder Jur? This would seem to be a good solution. Perhaps this is a step to a wireless system.

    IMO electronic shifting has little or no utility for folding bikes. The advantages are that it will (in theory) shift smoother and faster, while the cons are added weight, bulk, complexity, and dependence on batteries.

    Plus, I seriously doubt that electronic shifting will go wireless, certainly not anytime soon.

    Tho' at least it isn't a reinvention of something that's been around for decades, like shaft or belt drives...

    Actually, those "advantages" were not my point. Cabling a folding bike for the appropriate cable pull without interfering with the fold is my point. With an electric motor driving the derailers, one doesn't have to worry about cable tension -- you can even have common wire connectors -- so cycling performance and the fold/separation/packing should be much better.

    Although there are limits since only the derailers have electric motors.

    I have never even owned a car with an automatic transmission. I don't think I'll be buying an electric-shift bicycle.

    I guess, I've never really had a problem with that. Electronic shifting in general sounds like a solution looking for a problem. An expensive, bulky, complex, battery-driven solution.
