    Hello! Total newb here and this is probably a dumbass question buuuuuut....

    Can coasters be added to a wide wheel? I'm talking really fat, like 4" or larger? Planning making my first bike (chopper), I cannot for the life of me find out anywhere how large I can go using a coaster. I may just be reading something wrong, but it would help me greatly. Thankies guys

    coaster brake? a couple of cheapish bikes have them that wide. weather it'd be worth buying the whole bike to get it (and if they sell/sold there) would be your call. the schwinn manta ray (the one re-released back around the mid-2000's) in a 20" wheel, or a walmart mongoose beast in a 26" wheel. also maybe a parts site called chopper us may have them as just the hub.

    If you're using a standard coaster brake hub, the tire and rim couldn't really extent out beyond the sprocket- but I don't know exactly what that measurement would be.

    For a super wide tire, you'd probably need to bend the brake arm so that it could clamp onto the frame, or make some kind of adapter

    I was thinking your chain needs to be reasonably straight with the sprocket and has to clear the tire.
    Come to think of it, they do build road bike wheels off-center on the hub, so guess you could do that.
    Normally, the frame on a bike limits the tire size. My Worksman uses 2-1/4" wide tires, and they don't have much extra room, either. If you make the frame wider, then a standard crank arm won't clear it, which is why Worksman cuts it close there. If you're custom-building a frame, you can change all kinds of things up. And if you're building a bunch of oddball frames (like, say, Surly), then you can get some OEM stuff made up for not too terribly much to help with the issues that come up.

    Yeah, the frame has to clear the rim width. But from the hub you can probably build some extensions. It won't be easy. The tires on my Giant Stiletto are over 3", so that's getting fairly wide. But again, the hub was built for the job.

    There are pics of custom-built rims on the Atomic Zombie website.

    Too bad you arent closer. I have a couple coaster hubs with 170mm spacing that I took off of Mongoose Beasts. Can you weld? If so maybe widen a stock coaster? Use 3/8 all thread for the axle. Stock coaster hubs are 120mm spacing I think. If you could make it 50mm wider you would be set!
