All Sturmey-Archer gear hubs use epicyclic (planetary) geartrains of varying complexity. The AW is the simplest, using one set of planetary gears with four planets. The AM uses three compound planets with differently sized cogs machined from a common shaft to engage the gear ring and sun gear separately, while the close-ratio three-speeds, and hubs with four or more speeds, use multiple ...

This used similar cycle parts to the V-twin including the three speed gearbox. A smaller engined machine with a 2-3 ⁄ 4 horsepower J.A.P. engine continued to be available, this using a Sturmey-Archer 3-speed hub [4] (Sturmey-Archer bought the Armstrong-Triplex Three Speed Company from the New Hudson Cycle Company in 1914).
