I just got a H/D rear hub kit for my bike but cant see how to go about setting it up. My bike is a peddal start but I cant see how to put a free wheel gear on the hub all it has is a place to thread a drive / pedal gear / on the right hand side . Is there a free wheel gear that can screw on to this hub?? ,any body have any ideas on this. I have included a photo of the hub so you can see the right side.
