    external gearing with coaster?

    Does anyone know of a hub for external gearing that has a coaster brake, i just cant find one.
    I dont really care how many speeds it has. I know there are internally geared hubs with coasters but im curious about the price for externally geared coaster hubs

    You can't find one because such a hub is not possible. A coaster brake requires that you apply force by pedaling backwards. A rear derailleur makes that impossible - instead of applying the brake, the derailleur cage would rotate.

    Yup, There have been kick back 2 speed coaster hubs, gear internal .. Bendix.
    back when Schwinn was in Chicago..

    But Drum brakes work better than coaster brakes,
    then you can put a 6 speed freewheel on it. .

    But you can get a single speed coaster brake, then..
    get a 2 speed internally geared Crankset from the Swiss machine shop
    of Florian Schlumpf, the 2nd gear a 1.6x of the low gear.

    your desire will require money .. don't be cheap.

    Yes, but Bullseye (aka Roger Durham, the hubs & cranks manufacturer) made a one-way clutch & lever mechanism that pulled a cable when the cranks were backpedaled. This activated the brake (or brakes). This is rarely seen- it's usually a very custom job.

    My friend Jane has one on her hand-and-foot powered recumbent: http://www.ohpv.org/events/albums/jf...s/IMAG0238.htm . She's using a Rohloff hub, but it could just as easily be a derailleur setup.

    Coaster brakes have a tonne of power which I have always found drum brakes to be lacking, plus no cabling, hurrah!
    ... but also no derailer apparently

    I don't think i will be pursuing any of these crazy custom jobs, only stock bits for me.
