4

The Speedway 4 (often styled Speedway IV) is a full-size single-motor electric scooter from Minimotors, the Korean maker behind both the Speedway and Dualtron lines. It sits one tier below the dual-motor Speedway 5 and was, for several years, the brand's flagship single-motor commuter. Power comes from a rear-mounted BLDC hub motor rated around 600 W nominal with a peak of roughly 1,600 W, fed by a 52 V lithium pack. The deck accepts several battery capacities; the most widely cited configuration is 52 V / 30.5 Ah (about 1,586 Wh), and retailers also documented 20 Ah and 26 Ah packs, which is why quoted range and energy figures vary between sources. On the largest pack reviewers and the distributor cite a top speed near 60 km/h and a range of roughly 80 km at a 75 kg rider weight and steady cruising pace. The scooter rolls on 10-inch pneumatic (tubed) tyres, carries front and rear mechanical disc brakes with 140 mm rotors plus a regenerative electric brake, and uses dual spring suspension at both ends for ride comfort. A 3rd-generation EYE throttle dashboard exposes three ride modes and adjustable parameters, and the Speedway 4 was one of the first in its class to integrate turn signals, a feature it shares with the later Speedway 5. There is no companion app. Folded, it stays compact enough for car transport despite a roughly 24 kg kerb weight, and the frame is forged aviation-grade 6082-T6 aluminium.
