When the designer, Edward Carl Fredrich Otto , was negotiating with BSA for the manufacture of the “Otto,” being anxious to prove that his machine was correct in design and principle, he demonstrated his invention to the Directors by mounting the machine on the large table, riding it backwards and forwards, showing the method of balancing, and explaining the details of the somewhat complicated system of steering.

In October the BSA Bantam was released, the bike had telescopic forks, a rigid rear end, direct electrics, shovel front-mudguard and fishtail silencer. She had three gears, a maximum speed of around 50 mph, good brakes for the time and fuel economy of over miles to a gallon of fuel, interesting when compared to the lower effeciency of similar modern bikes.
