Backpedal Bicycle Brake
|
|
|
|
|
Econologica has developed a very simple backpedal brake, particularly suited to activating the rear stirrup brake of traditional English bikes that are widely copied in China and India. This idea is offered free to bicycle manufacturers, but liability and safety concerns unfortunately prevent us making it available for do-it-yourself.

An old bike frame with the seatstays cut off makes a lightweight trailer bed with an offset arm for loose vertical bolting to your bicycle for short loads. To carry long lengths such as lumber, tie their middle to the trailer and suspend the heavier end from your bicycle's seat tube.
The trailer axle can be a 1" EMT (electrical conduit) which just fits the head tube of the lugless frame. To fit old 10-speed rear wheels, replace the axles with ½" pedal axles. Cut the 10-speed axle generously around a cone and drill it out to mount the cone on the small end of the pedal axle. Chuck the axle piece and use a stationary center drill and then H&J letter drills clamped upright in a vice to do this in a drill press. Cut the bike crank threaded end off to weld it flush to the end of the 1" crosstube. Make sure you mount the wheels freewheel-side in, as they are dished, and mount the lefthanded crank thread on the lefthand side. The trailer doesn't take much room at all to store, as the pedal axles are easily unscrewed to remove the wheels. Prototypes for sale locally on Vancouver Island.
