SPEEDWAY
Speedway 4
SKU: SCT-SW4-001
Description
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.

Model history
Minimotors was founded in 1999 in Busan, South Korea, and grew into one of the most recognised makers of high-performance kick scooters under its Speedway and Dualtron brands. The Speedway line traces a clear lineage of numbered single-motor commuters; the Speedway 4 (Speedway IV) succeeded the earlier Speedway III/Swift generation and pushed range substantially higher by moving to a high-capacity 52 V pack. It became the brand’s go-to single-motor long-distance commuter before the dual-motor Speedway 5 arrived as its successor, carrying over signature touches such as the integrated turn signals. The model remained a popular long-range option and a common donor platform for replacement 52 V batteries, which are still sold by several European parts suppliers.

Pros & cons
Pros
- Long real-world range from the large-capacity 52 V battery options
- Dual disc brakes plus regenerative braking give strong, redundant stopping power
- Full dual-spring suspension and 10-inch pneumatic tyres smooth out rough surfaces
- Integrated turn signals improve visibility and signalling in traffic
- Customisable three-mode EYE dashboard suits both new and experienced riders
Cons
- At around 24 kg it is heavy to carry up stairs despite folding
- No companion app for diagnostics or firmware updates
- Quoted range and energy figures vary widely because of multiple battery configurations
- Single-motor traction limits steep-hill climbing compared with the dual-motor Speedway 5
Verdict
The Speedway 4 is a capable single-motor commuter for riders who prioritise distance and ride comfort over outright dual-motor acceleration. Its large 52 V battery, redundant braking and full suspension make it well suited to long city and intercity trips, though its weight and the absence of an app temper its everyday convenience.
