Fizzy
Affectionly called the 'Fizzy', The FS1 was a Yamaha moped of the 1970s. Various letter suffixes were added to indicate model variation to suit local regulations, such the FS1-E for England, FS1P/DX NL and others.
The FS1-E was the UK model. Machines registered in the UK from 1 August 1977 were restricted to a maximum of 31 mph (50 km/h).
Originally the FS1-E was built as a five-speed transmission light motorcycle. It was originally called the FS1. Due to the regulations in Europe, the FS1-E was downtuned with a four-speed transmission.
The Yamaha FS1-E has a 49 cc single cylinder two-stroke air-cooled rotary disc-valved engine with a four-speed gearbox.
About 200,000 were produced for the UK market. An award winning short film was produced in 2006 a entitled 'Fizzy Days' encompassing the bikes and the era.
The FS1-E had the ability to be powered by pushbike type pedals since this was a legal requirement for registration as a moped in the United Kingdom and some other European countries at the time.
The special pedal cranks allowed both pedals to be rotated forward so that the pedals would form motorcycle-style footrests in normal operation. To engage the pedals, the left-hand pedal crank could be rotated 180 degrees backwards and locked, and a drive gear engaged allowing the user to pedal. A short chain connected the pedal drive to the main engine-chain drive system. Pedalling was hard work for the rider: there was no freewheel and the pedal gearing was very low. The engine could be started with pedal drive engaged, causing the pedals to rotate under engine power when the bike was in gear. In practice, the cam and shaft arrangement to engage the pedals frequently seized (in normal operation, a rider would very rarely engage pedal-drive as it was less tiring to push than to pedal).
