i want to convert my coaster brake system,I am wondering, if i install a rear disc mount freewheel style wheel so i can directly bolt up my sprocket to the hub, is there a one speed cassette available, or do i have to install to install a multi speed cassette, and only use one cog of it?


Thanks
 
The answer could be any of the above? If the bike you are putting this new wheel on is the Felt Red Barron mentioned in your signature, you have fewer choices. The frame spacing for a coaster brake hub is usually 110mm. The rear triangle on the felt is very beefy to say the least and would be very difficult to widen to fit a multispeed disc brake hub which are 135mm wide. Mountain bike single speed disc hubs are available but again they are 135mm wide. The type of hub that you need would be a BMX singlespeed Disc hub. BMX rear hubs are narrow like the coaster brake hubs 110mm. If you are talking about a bike other than the Felt and the frame material is steel then you can pick just about any type of disc hub no matter the width and cold set/bend the rear triangle to fit the new hub.

This took a bit of a while but I need this info too!
Thank You Blaze!!

It seems my coaster is acting up again even after greasing it up. I used to do this back in the day when coasters were popular and freewheel for BMX bikes were expensive.
I believe it's a 1/2 inch inside diameter and about an inch outside diameter washer but bring your axle to be sure.
I'm probably gonna do this to mine after finding a rear cable brake.... but I'm gonna try to fix her again.
I like the more positive engagement a coaster brake gives but it seems engines are hard on them.

Thanks ocscully, and large,the bike im refering too is a felt red baron, i have a older huffy 10speed 26in mountain bike freewheel rim just to fit things up, and it fits perfectly im guessing it is the 135mm size, i measured my frame it is exactly 5inches wide not sure what that is in mm sizing though,so im thinking the normal mountain bike 135mm single sprocket will work, also i have the steel frame.

Ok i found a conversion caculator, the rear sizing is the 130mm size or very close to it anyway, so im guessing my huffy freewheel rim i used to test fit is a 130mm, but i noticed 130mm hubs are available, the felt frame material seemed like it could be cold set as you mentioned to the 135mm size though if need be, any thoughts?

Felt must add some extra spacers to their coaster brake rear hubs. But the fact that your bike has the wider spacing to start with does make sense as felt sells several models of the cruisers with the Shimano internal 4 & 8 speed hubs and those are spaced 130mm. In the wider spacing there are alot of great options available. For my GiantStone project I bought the Nashbar Single Speed Cassete Disc rear hub. They had it on sale for $35.00 some months back. I also bought some Sun Mammoth Rims from them for $15.00 each. The Mammoth rims I think will make a great motored bike wheel if you don't feel the need for 12g spokes. They are quite wide and beefy but not as wide as the Felt rims.

Yeah the coaster wheel does have spacers on the ends, do you think it would be smarter to go with a 135mm hub instead of a 130mm, the 135mm seems like a more common size, atleast with complete rim sets ive seen.

Yes, I would go with the 135mm hub. I also think that you will have a minimal amount of fuss getting the wider hub into the frame.

Thanks again, i compared my frame to a 135mm mountain bike today, there wasnt much difference, something like a 1/2'' difference, i will need to bend it some, but it looks like it should be all good.
