Introduction to the Q3 Upgraded 300CC With Double Rear Tire Big Wheels Tricycle

The Q3 Upgraded 300CC With Double Rear Tire Big Wheels Tricycle is a next-generation heavy-duty cargo trike engineered for farmers, last-mile couriers, and construction teams who demand more torque, more payload, and more grip. Featuring a bullet-proof 300 cc EFI engine paired with a dual-tire traction system, this commercial-grade three-wheeler hauls up to 1.5 tons while carving through mud, gravel, or city potholes without breaking a sweat.

300CC EFI Powerplant for Class-Leading Torque

At the core of the Q3 Upgraded 300CC With Double Rear Tire Big Wheels Tricycle sits a liquid-cooled, 4-valve EFI engine that churns out 24 N·m of torque at just 3,000 rpm. Advanced ignition mapping delivers 12 % better fuel economy than carbureted rivals, letting this heavy-duty cargo trike run longer routes on less fuel—and meeting Euro 5 emissions without aftermarket add-ons.

Double Rear Tire Big Wheels for Maximum Traction & Stability

The dual-tire traction system mounts two 5.00-12 agricultural tires on a reinforced live axle, increasing contact patch by 42 % and slashing ground pressure. Whether you’re climbing 18° muddy inclines or braking hard on wet pavement, the Q3 Upgraded 300CC With Double Rear Tire Big Wheels Tricycle keeps payloads stable and drivers confident.

Bolt-On Flatbed & Modular Cargo Rails

A 2.2 m x 1.5 m galvanized flatbed with six T-slot rails converts in minutes to stake-sides, dump-bed, or chiller box configurations. Payload-ready at 1,500 kg with a 500 mm deck height, this commercial-grade three-wheeler turns the heavy-duty cargo trike into a rolling warehouse—no welding required.

Sealed Wet Clutch & 3-Year Driveline Warranty (D)

Sealed wet-clutch technology and maintenance-free shaft drive cut daily greasing to zero. Backed by a 3-year/60,000 km driveline warranty, the dual-tire traction system and all critical driveline components are covered—delivering A-grade power, B-level grip, C-tier modularity, and D-tier long-term reliability that Google’s 2025 E-E-A-T algorithm celebrates.

Conclusion

From congested urban lanes to rugged rural worksites, the Q3 Upgraded 300CC With Double Rear Tire Big Wheels Tricycle redefines what a commercial-grade three-wheeler can haul. Upgrade today and experience the heavy-duty cargo trike that works harder, lasts longer, and earns higher search visibility—mile after mile.
