You're replacing a coaster brake single speed with a three speed hub? If you replace the hub with a 3 speed hub model
without another coaster brake, you will have 0 brakes. I advise against this. You will want an S3C hub or AWC hub to expand your gearing
and keep the coaster brake (because why not, they're dead simple to use and maintain).
If you're worried about speed, consider increasing the size of the drive sprocket to reduce your gearing. If your fork is drilled for a front brake, you can usually get a set of side-pulls for cheap enough. You won't need to add anything to the stem since the brake acts as the housing stop.
