The two versions can be identified by the shape of their gearbox covers one-speeds have circular gearboxes while two-speeds have rectangular gearboxes. Maxis were produced in both E50 (one speed) and ZA50 (two speed) versions. For detailed information, see the Puch horsepower differences. The differences between the 1.5 HP and 2 HP versions are minor, the 1.5 HP version can be altered to effectively become a 2 HP version by derestricting the airbox, exhaust pipe, removing the head gasket, and re-tuning the carb. The Maxi's engine came in three different horsepower ratings: 1, 1.5, and 2 HP, which correspond to mopeds limited to 20, 25, and 30 m.p.h., respectively.
