Just bought (cheap) 2 old "Earth Cruiser" bikes to use on the beach. Coaster brakes barely worked, so I am having the coaster hubs (ancient Suntour) overhauled. I hope that helps, though I am not very optimistic. Any advice/links/part supplier ideas for adding a front brake to these great old clunkers? Or should I just do what I do best - ask the bike shop to fix it? Thanks for your help.
