band drive to each wheel, the steering effected by increasing or decreasing the tension on each band. Direct spokes to crescent rims, c1881. The whole in sound structural order, thinly repainted and with largely original components save for saddle (inter-War) and drive bands. The Otto was an early form of safety bicycle - its two track format is commonly called a 'Dicycle' to differentiate it from the in-line two wheelers. The machine had the advantages of a tricycle in its low riding position and open front (allowing it to be ridden by women wearing skirts) but with greater efficiency by lacking the friction of a third wheel. Furthermore as balance was achieved by fore and aft, rather than side-to-side motion, novice riders were merely pitched forward on to their feet in learning to ride the machine, a rear jockey wheel preventing a backward fall. So effectively could the machine be controlled that legend has it that it was demonstrated to the Board of BSA (which took on its manufacture) by being ridden from one end of the boardroom table to the other. Some 2000 machines were supposed to have been built, but only a handful are known to survive. Although BSA were famous for component manufacture, the Otto was one of only two machines the company built in the 19th century - the other being an equally rare safety bicycle of 1885-6.
