What I am looking for is an all purpose hub. One that will accept sprockets, wheels and brakes. Be way cool if the width was adjustable. Would really like to have a front brake on the Jimmy Gote and replace the rear hub at some point. I do not have access, yet, to a lathe. I do have some ideas on how to make a kit, but requires lathe work. The wheel hubs I see do not lend themselves to custom applications. I went with a go cart axle stuff on mine. Works, but what a pain to tear apart, and keep all the set screws tight. Any ideas? I did a search here and did not come up wit much.
