250cc Commercial Freight Tricycle

Advantage

The power unit features a 175cc-class water-cooled engine platform with an actual working displacement of over 250cc and a rated output power of more than 1000W. The water cooling circulation system quickly dissipates heat generated by continuous cylinder operation. Compared with air-cooled engines of the same level, it reduces power thermal fade by over 40% under high-temperature summer conditions and long-time low-speed heavy-load working conditions, significantly improving engine stability and service life. Matched with a freight-tailored transmission, it reaches a designed top speed of 50–70km/h and handles a maximum gradient of ≥25°. It delivers smooth full-load takeoff and maintains steady traction on steep village slopes and dirt farm roads without frequent gear shifting and throttle adjustment. Running on a 12V standard electrical system and equipped with a 10–20L large-capacity fuel tank, it achieves a driving range of over 150km on a single tank under comprehensive cargo conditions, covering daily round-trip demands between towns and villages. This effectively cuts refuel stops and improves daily operation efficiency by around 15%.

The chassis frame is integrally welded with 50*100 thickened rectangular steel pipes, featuring excellent torsion and bending resistance. 250cc commercial freight tricycle resists frame deformation and solder joint cracking even after long-term full-load driving on bumpy roads. The rear axle adopts a semi-floating booster axle matched with a 60-type thickened axle tube, providing sufficient load-bearing redundancy and low power transmission loss. It delivers abundant torque output during full-load takeoff and climbing, handling heavy-duty scenarios with ease. The braking system combines front drum brakes with rear hydraulic drum brakes. The rear wheels are fitted with 220mm extra-large brake drums that deliver ample braking torque with linear and sensitive response. Drivers can control speed smoothly through intermittent braking on full-load downhills. With excellent thermal stability, the brakes maintain consistent performance even after long-time continuous braking, fully ensuring heavy-load driving safety.
