The 1904 360 cc Advance 2¾ hp (2.05 kW) motorcycle on display at the National Motorcycle Museum (UK) is thought to be the only complete Advance motorcycle in existence. The engine has an automatic inlet valve above a mechanical exhaust valve and the rear wheel is driven by a belt from the crankshaft. Pedals and a free-wheel hub are provided for starting and helping the engine on steep hills. The handlebar grips, pedal blocks and the box for the ignition’s accumulator are all made of wood.
The 2¾ hp engine was replaced by a 3 hp (2.2 kW) version, a 3½ hp (2.6 kW) and a 6 hp (4.7 kW) V-twin, all with the same basic design of automatic inlet valves and a one-piece cylinder head and barrel. The Advance engines quickly gained a reputation for reliability and were much in demand from other motorcycle manufacturers. In 1907 Advance's sales catalogue listed a range of motorcycles with the different engines and a ladies version of 3 hp. In 1908 Advance appeared for the first time in The Motor Cycle as motorcycle manufacturers, with a range of motorcycles and three-wheelers including a new 9 hp (6.9 kW) motorcycle with an aircooled engine.
