    don't know about unicycles, but if you've ever seen one of those kids "green machine" trikes, the work that way.

    Schlumph makes something like this, I think. I think it's only 2 speeds.

    I think what you really need is a Shimano Integer front freewheel crankset, they came on some old Bike Boom Schwinns. They got kind of a bad rap because they were paired with the Positron "indexed" derailleur but it was actually kind of a neat concept. I keep wanting to build a bike that can use one but they take a bigger cup like you use on a Ashtabula bottom bracket.

    You might have to end up having to fab your own custom hub.

    Make the back two wheels straight if your wanting a "BigWheel" type ride.

    I think so. I got a Mongoose kids trike (pics in the costume thread)- straightaxle in back, and rear wheel steering. The front wheel drive is strange- the pedals turn and only grab the wheel sometimes. It might be one of those old 2 speed kickback hubs; so it would coast if it is. The disk brake is on the back axle.

    They are very hard to find. Coker used to make a 36" pennyfarthing (highwheeler) with a freewheeling front hub. They used a sort of "one-way" bearing to freewheel, not an actual ratcheting mechanism, and therefore they don't last very long. I've never seen anybody offer one for commercial sale, but if you do a search for "freewheel unicycle" you'll find a few threads on it. If you find one for sale, let me know, I'm wanting to build my own pennyfarthing with one.

    sorry, i just post at work now so i'm just seeing this again. but no, the only way i know of is to find a green machine at a thrift store, flea market or something. maybe craigslist?

    "Schlumph makes something like this, I think. I think it's only 2 speeds." They make a geared unicycle hub, but there's no freewheel in it.

    The only one I've heard of is the one mentioned above by Coker, this was on "The Wheelman".

    In the Past a Shimano attempt, Positron .. front freewheel crankset BB combo.

    You don't freewheel on a Unicycle .. it is the original fixed gear.
    Schlumph makes something like this, I think. I think it's only 2 speeds.
    there is a planetary gear ratio change in those unicycle hubs
    direct and overdrive, but no freewheel.

    site says a 24" wheel, in the high range, acts like a 36" wheel, for cruising speeds.
