Staton-Inc., a motorized bicycle manufacturer of long standing, also uses a rack-mount with either a tire roller-mount (friction drive) or a chain-driven, geared transmission. Other manufacturers produce kits using small two- or four-stroke gas engines mounted in the central portion of the bicycle frame, and incorporating various types of belt ...
Ixion engine on a Komet motorised bicycle, ca. 1902. This system is used, for example, to drive the spools in some tape recorders.In a typical configuration, one of the cylinders is the axle of an electric motor, say 1 mm in diameter, while the other is a disk with a hard rubber rim, say 50 mm in diameter, yielding a 1:50 mechanical advantage.

With an improved 4-hp version with a Belgian Vivinus engine he travelled through the Far East from 1901 to 1903 and built Wenkelmobils adapted to the tropical climate in Java, where petrol was very cheap. [11] The construction followed that of light American steam cars, with a standing engine in the rear and friction drive. [12]
Initially the engines were supplied separately but from 1952 Bridgestone produced a bicycle fitted with the engine, the BS21 Bambi. [4] The 26 cc engine was mounted above the rear wheel and was inverted. [5] The rear wheel was driven by a friction drive on the tyre. 38 cc BS-31 and 49 cc BS-41 were later added. [4]
