Maxi N: A rigid frame lacking a speedometer that was the cheapest model, and dubbed the "Poor man's maxi".
-
Maxi Sport MKII: Has a full suspension, mag wheels, the ZA50 (two speed) engine/transmission, a longer seat (but not long enough for passengers like the maxi D or LS model).
-
Maxi Nostalgia: was only available in 1976. It is a black/gold Maxi with decals styled after Puch's turn-of-the-century motorcycle logo. Its predecessor is the Newport.
-
Newport: Same as a Maxi S, but has different decals and hand pinstriping and sometimes a brown saddle, and comes with reflective whitewall tire.
-

-
Maxi Guam Edition: a few Maxis that showed up in the United States that claimed to be manufactured in Guam. These have Honda-style controls where the switches integrate into the lever/throttle housings and come stock with turn signals and sidecovers that enclose a battery. Guam built Maxis are claimed to be built better than the USA models.
-
Maxi BMX Special: Produced as a limited run in 1976 to celebrate the success of the company's BMX bicycles, production lasted only three months due to poor public reception. It featured the single speed E50 engine/transmission.
Engine
The Puch Maxi uses a 2 stroke 48cc two stroke gasoline engine of 38mm bore 42mm stroke 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, the E50 has one, while the ZA50 has two. (one for each gear)
