Coaster Dummy-Rim Rear Brake
Coaster brakes were popular in the USA and in Europe, though less so in Great Britain. This rear brake is a very odd feature, operating onto a dummy rim rather than the hub. Apparently introduced by Sheppee for their machines in 1925 (though fitted to this 1924 model), you can see in the picture below how the coaster brake mechanism works on the rim. Motorcycles had recently started moving from belt drive to chain drive, so presumably there was a surplus availability of dummy rims at that time.
