Single speed hub with a rear brake?
 

I am building my first bike in 8 years and looking at doing a fix gear or ss. What I would like to know is it possible to have a rear hub that lets you cruse like a single speed but will also act like a brake on a fix gear? If so what companies make that type of hub for a fat tire?

Thanks

AHH so is coaster brake is the term used for that type of hub?

A good coaster brake will allow you to skid the back wheel so in that, it stops as well as a fixed gear (sans brakes) and whenever possible, I have retrofitted many coaster equipped bikes with an additional front brake to improve the braking.

Coaster brakes were not designed for high speed use or long descents as they generate a great deal of heat and have a tendency to fade when they get hot.

This is my 1940 road / path racer and it was equipped with a front brake after I was unable to prevent myself from broadsiding a car that pulled out in front of me... the brake was working as well as a coaster could and know that if I had a front brake I would not have hit the car.

It is too fast a bike to only have a coaster brake and is exceptionally fast on descents... a coaster brake would get so hot on these that it would burn your fingers and probably stop working.

I know this from experience.
