I think some brakes on my beach cruisers , besides the coaster brakes would be a good idea. I'm thinking either caliper brakes or even discs would be good. A couple of mine have black rims so I know what the rims will look like after a short time. I see discs on a lot of mtn bikes that I would normally not buy but I might have to buy a couple for the brakes. Anybody on here added brakes ?
