QS180 motor kit is engineered for electric vehicles, built to deliver exceptional heavy-load performance and adaptable speed with climbing capabilities.

With two configurable gear ratio modes (1:8 and 1:4) and a standard 195/50-12 tire fit, it excels in a wide range of commercial and utility-focused e-mobility scenarios—all while maintaining reliable speed, climbing power and operational stability under full load.

1. Urban & Suburban Heavy-Duty Cargo E-Tricycle Delivery
Matched Configuration: 1:8 gear ratio (max 60kph, 15° climbing slope @20kph for 120s under 980kg)

This is the primary application scenario for the QS180 motor kit. Urban and suburban cargo delivery demands consistent heavy-load capacity, strong climbing ability, and a steady speed suitable for city road limits.

The 1:8 gear ratio mode delivers a perfect balance of high torque and controlled speed: it easily ascends 15° steep slopes at a stable 20kph for 2 minutes with a full 980kg load—ideal for navigating hilly urban streets, delivery depots with ramp entrances or suburban roads with uneven terrain.

The 60kph max speed aligns with most urban low-speed freight regulations, while the 195/50-12 tire ensures excellent ground grip and load-bearing for heavy cargo. This configuration is a game-changer for professional delivery fleets, local couriers and small freight businesses using e-tricycles as their primary transport.

2. Rural Passenger & Light Cargo E-Tricycle Operation
Matched Configuration: 1:4 gear ratio (max 90kph, 8° climbing slope @10kph for 10s under 980kg)

Rural areas call for faster travel speeds for longer inter-village/ town commutes, with milder climbing needs compared to urban terrain—making the 1:4 gear ratio mode the ideal choice.

The 90kph max speed cuts down travel time for rural passenger e-tricycles and light cargo transport. Even with a full 980kg load, the qs180 motor kit effortlessly climbs 8° gentle rural slopes at 10kph, ensuring smooth passage on country roads with slight inclines.

The robust 195/50-12 tire also adapts to unpaved rural roads, providing durability and traction on gravel or dirt surfaces.

3. Custom Heavy-Duty Electric Utility Vehicle Conversions
Beyond standard e-tricycles, the QS180 motor kit is a top choice for custom heavy-duty electric utility vehicle conversions.

Both gear ratio modes can be tailored to the specific niche: 1:8 for static heavy-load vending/ collection (with strong climbing for residential waste collection routes) and 1:4 for mobile medical supply transport (faster speed for time-sensitive deliveries on mild terrain).

The kit’s compatibility with the 195/50-12 tire and 980kg load capacity ensures these custom vehicles meet the rigorous demands of specialized commercial use, while its regenerative braking and high efficiency (85~92%) keep operational costs low for long-term daily use.

The QS180 motor kit’s core strength—unmatched heavy-load performance paired with adaptable speed and climbing capabilities—makes it the definitive power solution for commercial and utility e-tricycles.

Its alignment with real-world freight, transit and industrial needs, combined with a durable, load-optimized tire fit, ensures it delivers reliable, efficient and cost-effective performance for all professional e-mobility operators.
