Page 37. 1957 Lambretta 48 Moped – UNSOLD

1957 Innocenti Lambretta Moped Model 48


The weather was unseasonably pleasant in February and I celebrated the sunshine by zipping around Sussex on my Model 48.

My usual hack is a 1940’s motorcycle, so I was a little apprehensive before using the 48. But it’s such an absolute joy to ride that I was soon seduced by it. To start, you simply put it into neutral and press down on one of the pedals. After a few miles of practice I soon got used to it. Handling is excellent, and despite its cc it’s no slouch. Top speed is around 30mph (no speedo) so like any moped it’s not a long-distance machine. But for nipping in and out of traffic it’s as good as anything modern.


The Lambretta model 48 II moped was produced between 1959 an 1961. If you see one of these unusual – and delightful – little Lambretta mopeds, it will most likely be the 48 II model.


However, my Lambretta moped is the much rarer ’48’ – the first series which manufactured between 1955 and 1957.

“The scooter production in 1955 reached a good level, even if not as good as in 1953,” says the Uk Lambretta Club.


“At the beginning of the year a high-wheel 48 cc two-speed motor-bicycle was launched (“Lambrettino 48″), with a production of 6,000 units and 22,000 units in 1956. Increase in total production (scooters + motor-bicycles) amounted to 20%.”


Though this early model was an Innocenti, it was called a ‘Lambretta 48.’ So it’s a bit confusing when the British Lambretta Club also explains: “The first moped introduced by Lambretta was the 48 II, which was launched in January 1959.”


The single beam cradle type frame was light and rigid, and held a 47.75cc engine. Whilst not being powerful at 1.7bhp the two speed gearbox made the 48 capable of 31mph. A small fuel tank built into the frame, air filter also housed within the frame and a single seat gave this small Lambretta the rider the basic needs.


The 48 could be used as a conventional bicycle by disengaging the pedal drive.


A small tool box was fitted underneath the rear rack, and the 48 came complete with a pump for the tyres.


The 48 II was replaced in 1966 by the Lambrettino.


Since buying this Lambretta 48, we’ve done a lot of work to restore it mechanically. It had been off the road since 2001. It’s amazing how carried away you can get; once you’ve started restoring, there’s no point ignoring anything that needs doing and in no time at all you’ve spent a small fortune on it!


It now has new tyres, an MOT and tax, and runs well.



And here’s me and the ol’ 48 on the Sussex Cyclemotor Run…
