300cc 3 Wheeler Auto tricycle
a 300cc engine delivers 13.5 Nm of torque at 6500 rpm, tuned for strong low-end torque, easily towing 1500 kg of cargo uphill.
Braking system features motorcycle-grade hydraulic disc brakes: a 220 mm disc on the front wheel with dual-piston calipers.
HX-09 300cc 3 Wheeler Auto tricycle is equipped with a single-cylinder, four-stroke, water-cooled 300cc engine with a bore × stroke of 77 × 64.8 mm and a compression ratio of 10.0:1. It features CDI ignition and dual-mode electric/kick start, and is paired with a 5-speed automatic transmission. Its maximum power output is 13.5 kW (±5%) at 6500 rpm, and its maximum torque is 23.5 N・m (±5%) at 5500 rpm, providing ample power reserves. The chassis uses a 40×100mm frame, and the cargo box dimensions are available from 2.2×1.4m to 2.4×1.4m.

Rear axle is fully suspended. Outer side of the half-shaft is connected to the wheel hub via a flange plate, and the wheel hub is independently supported on the axle housing by bearings. The axle housing bears all vertical loads, and the half-shaft is only connected to the differential via a spline.
Fully Suspended Rear Axle: Half-shaft is only responsible for transmitting drive torque. The vertical load and impact force of the wheels are directly borne by the axle housing, and the half-shaft does not bear bending stress.
Semi Suspended Rear Axle: Half-shaft not only transmits torque but also needs to support part of the wheel weight and road impacts, bearing the combined effects of torque and bending moment.

FAQ
Q1: What engine does the HX-09 300cc tricycle use?
A: The HX-09 uses a 300cc single-cylinder, four-stroke water-cooled engine. It produces 13.5kW at 6500rpm and 23.5N·m of torque at 5500rpm. The engine uses CDI ignition and supports both electric and kick starting. With a five-speed transmission, it provides enough power for daily cargo transport, loaded starts, and uphill driving.
Q2: What is the cargo box size of the HX-09?
A: The HX-09 is available with a cargo box ranging from 2.2×1.4m to 2.4×1.4m. The actual size can be selected according to the vehicle configuration and customer's requirements. The spacious cargo area is suitable for transporting building materials, agricultural products, tools, equipment, and other goods used in daily commercial work.
Q3: What is the advantage of the full-floating rear axle?
A: On the HX-09, the half-shaft mainly transfers power from the differential to the wheels. The axle housing and bearings take the vertical load and road impact instead of putting that load directly on the half-shaft. This reduces bending stress on the shaft and makes the rear axle better suited to regular heavy-load operation and rough road conditions.
Q4: What is the difference between a full-floating and semi-floating rear axle?
A: A full-floating axle separates the driving and load-bearing jobs. The half-shaft transmits torque, while the axle housing supports the vehicle weight and wheel loads. With a semi-floating design, the half-shaft handles both driving torque and part of the wheel load. For a cargo tricycle that regularly carries heavy goods, the full-floating layout provides a more suitable axle structure.
Q5: Is the HX-09 suitable for heavy-duty cargo transport?
A: Yes. The HX-09 has a 40×100mm frame, a full-floating ninth-generation rear axle, double-layer steel cargo bed, and 5.00-12 tires. Combined with the 300cc water-cooled engine, these components are suited to cargo work where the vehicle needs to carry goods over different road conditions. The actual load should remain within the specified vehicle rating.
Q6: Can the HX-09 be customized for different markets?
A: We can discuss different configurations according to the customer's market and application. The HX-09 can be supplied with different cargo box sizes and other configuration options. Before production, customers can confirm details such as vehicle specifications, cargo box requirements, and shipping arrangements with our sales team. We also provide complete support for overseas orders and export projects.
