WEEROCK Tricycle Rear Axle Kit for 20/24/26 Inch Wheels
The WEEROCK tricycle rear axle kit is designed to convert standard scooters or bikes into a three-wheel configuration. It supports 20″, 24″, and 26″ adult trikes and uses a 5/8 inch (15.8mm) axle that fits hollow-hub wheels. A band brake is listed among its features, which helps deliver reliable stopping power in a trike setup. This kit is suitable for riders seeking added stability during cornering and on uneven surfaces. Installation may require basic mechanical skills and compatible wheel hubs.
GY6 50cc Carburetor, Ignition Coil, and Regulator Kit
This kit provides a comprehensive upgrade for 50cc scooters and mopeds powered by GY6 139QMB/139QMA engines. It includes a carburetor with ignition coil, voltage regulator/rectifier, and related components to improve fuel-air mixing, ignition timing, and electrical charging. It’s suitable for popular Taotao, Roketa, Jonway, and similar Chinese-made scooters. The combination aims to enhance engine performance, reduce oil leaks, and promote smoother operation across a range of 50cc models, making it a practical maintenance or upgrade option.
Twist Throttle Accelerator Handle Grips With Cable
This throttle grip and cable set is designed for 7/8″ (22mm) handlebars, a common size on many 50cc to 250cc dirt bikes, ATVs, and mini bikes. The kit features a 90-degree bend at the cable attachment area for easier routing and installation. It fits a broad range of 50cc to 250cc four-stroke applications, including dirt bikes, pocket bikes, and pit bikes. Besides improving control, it provides a reliable throttle response and compatibility with many aftermarket throttle assemblies, making it a versatile upgrade for a trike-conversion project.
Trike Rear Axle, 7 Speed, 5/8 Inch Axle
This trike conversion kit supports 20″–26″ adult trikes with a seven-speed setup. The axle size is 5/8 inch (15.8mm), and it is compatible with hollow-hub wheels. Constructed from high-carbon steel, this kit emphasizes durability for longer rides and varying terrain. It’s a practical option for riders aiming to add multi-gear capability to a trike conversion project while maintaining strength and reliability in the axle assembly.
50mm Cylinder Kit for GY6 Engines
The 50mm cylinder kit is designed to upgrade GY6 49cc/50cc engines by increasing displacement to around 100cc. It features a 50mm bore, a 13mm piston pin diameter, and a compatible outer diameter for piston rings and components. The upgrade aims to deliver more horsepower and torque, enabling better hill-climbing ability and acceleration. Installation requires mechanical knowledge of engine internals and compatibility checks with existing GY6-based scooters or mopeds.
Buying Guide
Key purchase considerations for a 50cc scooter trike conversion project include compatibility, installation effort, and safety. Consider these perspectives to guide your choices:
- Fitment and compatibility: Ensure the axle and wheel sizes match your frame and wheels (20″, 24″, 26″ options are common). For engine upgrades, verify that the cylinder bore, piston diameter, and mounting points align with your GY6 engine family.
- Durability and materials: Look for high-carbon steel or reinforced components for axles and frames to withstand added weight and rough surfaces. Durability matters more for long-term stability on a three-wheeled setup.
- Ease of installation: Some kits are straightforward bolt-ons, while others require welding, alignment, or electrical tuning. If you’re new to builds, prioritize components with clear instructions and compatible hardware.
- Maintenance implications: Upgrades to electrical, throttle, or carburetion affect maintenance frequency. Choose parts with accessible replacement options and commonly available spare parts.
- Performance balance: Increasing displacement or adding a trike can alter handling. Consider a gradual approach—start with a stable rear-axle kit, then add engine upgrades if needed.
- Safety considerations: Ensure braking compatibility (e.g., band brakes on trike kits) and verify that the overall weight distribution remains within the frame’s design limits. Proper installation and testing in safe environments are essential.
- Value and support: Compare warranties, return policies, and seller support. Given the range of brands, choose reputable sellers and verify compatibility with your model year.
Comparisons often reveal that trike-focused kits emphasize stability and braking, while engine upgrades target acceleration and hill-climb performance. A balanced approach—prioritizing a sturdy rear-axle kit first, then evaluating engine or throttle enhancements—typically yields safer, more predictable results for street use and recreational riding.
