Alpino is an Italian historical brand of auxiliary engines , scooters , motorcycles and triporteurs .
The company name was: Motobici sarl, later Moto Alpino and Stradella ( Pavia ).
Paolo Trespidi started in 1944 with the production of clip-on motorcycles for bicycles . Of course sales did not start until after the Second World War , but then there was also a need for cheap means of transport, which made the engines eagerly deductible. They also got a good name and in 1948 Trespidi’s company Motobici was one of the leading manufacturers of auxiliary and motorized bicycles in Italy.
This first auxiliary engine, which he called “Alpino”, had a single-cylinder two – stroke engine with two gears that drove the rear wheel through a chain , but it could be mounted in the frame or next to the rear wheel.
Until 1948 the engine remained unchanged, but then new models arrived: the Alpino S 48 had a 48cc two-stroke engine without clutch but with three gears that could be purchased as a separate engine or as a motorized bicycle. The model Alpino ST 60 had a 60cc engine and was mounted in a bicycle frame sold. In the same year, a roll drive spreader appeared, the Alpino R 48, also with the 48cc engine but without gears, and the Alpino ST 60 with 63cc engine, three gears and chain drive. There was also a real motorcycle, with a 98cc engine.
In 1951 the model R 48 was still in production, the chain-driven two-speed model was now called Alpino C 48 and with three speeds F 48. A 125cc motorcycle was also produced. This already had a foot switch, but still a trapezoid fork at the front. Behind were two spring / damper elements placed.
Now there was also a scooter , which was also called F 48. This was a special model. He had a double tube frame that ran down from under the footboards from the headset , but then made a kind of loop, creating a cage with the engine in it. The whole scooter therefore seemed somewhat like a snail with a snail’s house. There were also pedals on it. In addition, he did not have the usual small wheels, but 14- inch wheels, which almost made it look like a motorcycle.
In 1952 there was a new 125cc motorcycle and in 1953 the Alpetta R 48 motorized bicycle with roller drive and the Alpino Roma with a 49cc engine, two gears and manual gearshift . There also came a 75cc motorcycle. In 1952 records were driven with fully packed Alpino’s with an ovoid streamline . Andrea Bottigelli drove a world record on the flying kilometer with a 75cc engine. He reached more than 128 km / h. In the same year, the record was brought by Alpino over the flying kilometer at 129 km / h and the record about the flying mile at 92.18 km / h. Tamarozzi, Cagnazzi, Pennati and Sozzani drove records with 50cc engines, eventually reaching a top speed of 82.216 km / h. During these record attempts, tests with a 75ccfour-stroke engine with overhead camshaft .
In the years 1954 and 1955 were still primarily made two strokes, but there was now also the Alpino 175 4T, a pushrod -viertakt with four gears. There was also a 75cc DOHC Four-Stroke Tracer with four gears. In 1956 a new 75cc two-stroke scooter and a triporteur came in two versions: the 50cc-Alpe and the 175cc-Golia. The 125cc motorcycle was now available with 14 and 19 inch wheels.
When the production ended is not known with certainty, but it probably was in 1962.
