Puch Maxi
The Puch Maxi is a moped that was manufactured by the Austrian manufacturing company Puch through the 1970s and 1980s that is well known for its reliability, ease of maintenance, and fuel economy (up to 120 mpg). These mopeds gained wide acceptance during the 1973 oil crisis and are still widely available for aftermarkets, and mint examples are still valued by collectors today. It is started using a pedal start mechanism where the user provides the force needed to start the 49.9 cc two stroke engine, or can be ridden like a bicycle when the engine is disengaged . The later models feature a kick start mechanism. Models. The Puch Maxi comes in several models: Engine. The Puch Maxi uses a 2 stroke 49 cc gasoline engine that comes in three horsepower ratings: 1.0, 1.5, and 2 HP that limits the speed to 20 mph (32kmh), 25 mph (40 kmh) and 30 mph (48 kmh) respectively. However, these can be modified by de-restricting the airbox, carburetor, exhaust manifold, pipe, and the use of aftermarket and performance parts. Transmission. The engine is coupled to either a single speed E50 or a two speed ZA50 transmission. The versions of  the transmissions can be identified by the shape of the gearboxes: The E50 has a round gearbox whereas the two speed has a rectangular gearbox. Both transmissions use a centrifugal clutch.
