Picking a motor class from the published duty, not from a brochure adjective
ZP groups two-wheelers by motor class. The pages themselves say who each class is for.
1500W wheel-motor (ZP18L, ZP19L in its 1500W listing): urban medium-distance, household use on ZP18L, delivery mentioned on ZP19L. Speeds printed at 50 km/h on the 1500W columns.
2000W / 2200W (ZP24F, ZP24E, ZP20X): urban medium and long-distance, delivery market named, 55–65 km/h depending on column, 85–175 km eco-range with the larger pack. ZP20X is the central-motor exception, described for mountain roads and heavier riders.
3000W (ZP990C, ZP20U): delivery and passenger use, 80 km/h maximum speed, 165 km or 240 km eco-range. Use this class when the route or the passenger load outgrows the 2000W pack.
