@Phaedrus, I remember those coaster and BMX bikes with the back pedal brakes. When the first ten speed bikes came out, many of us had to learn how to use caliper brakes mounted on those curled handlebars. It was a steep learning curve. Braking with caliper brakes meant applying pressure on the rear tire first, then gradually applying pressure to the front caliper brakes. If a rider locked up the front wheel first, the rest of the bike would flip forward. We'd have to go to the local bike shop every few months and buy new rubber pads for the caliper brakes, I remember.
