Re: Identifying a jc higgins
the front coaster brake is an exercise in futility. it looks cool, but it's not very functional. you need a lot more leverage than the average brake lever will allow, and i don't want a giant motorcycle lever on my bike.
there's a few guys over at ratrodbikes.com who've made them, and there's a post here, too, but the idea comes from New Departure, a bearing and hub maker from 1890's or so to 1950's.
they made a front brake based on a coaster hub, but they stepped up the action with a finer threaded worm gear.
they show up on ebay now and then for about 3-500 bucks for a NOS one.
