This overview helps you compare core features quickly while aligning with common go kart rear wheel applications.
Complete Wheel Hub Kit With Tire And Brake Assembly
This package includes two wheels with tubeless tires mounted on 6″ rims, paired with a complete brake system and axle assembly. The shaft measures 740 mm (29.13″), with a spline-to-spline distance of 452 mm (17.79″), and a maximum shaft thickness of 22 mm. Aimed at DIY go kart builds, quad setups, or drift bikes, this kit provides a robust rear-wheel solution with an integrated brake disc and master cylinder caliper assembly. It also includes a T8F chain and a sprocket to help you connect the drive system efficiently. The kit’s wide components support heavy loads and repeated use, suitable for backyard tracks or small-scale racing projects.
Key considerations: ensure your frame supports a 29.13″ shaft, check bearing positions at 20 mm, and verify compatibility with aftermarket brake systems. The 13.0″ diameter tyre with a 3.93″ width offers stable ground contact for varied terrains. This is ideal for builders seeking an all-in-one solution with braking hardware included.
2 Pack 145/70-6 Tubeless Tires With Rim
These tubeless 145/70-6 tires come in a two-pack with rims, designed for go-karts, ATVs, and mini bikes. The nylon construction provides puncture and abrasion resistance, making them suitable for both dirt and paved surfaces. The tires are specially designed for soft to hard-packed terrains, offering reliable traction and stability with pressurized air support. They fit 6″ rims and are a practical upgrade for small to mid-sized rear-wheel assemblies, delivering a balanced ride on a variety of tracks.
Highlights: tubeless design simplifies mounting, dual-pack convenience, and a versatile tread suitable for mixed-terrain use. Check rim compatibility with your current wheel hub and confirm the axle dimension before purchase.
RZEOZU Mini Bike 145/70-6 Wheel Kit
The kit targets compatibility with a broad range of 79.5cc to 105cc mini bikes and go-karts, including Coleman, Motovox, Baja, and related brands. It uses a 12 mm axle and features a V-shaped tread design that enhances traction on both wet and dry surfaces. Fitting a 6″ rear rim, the kit is designed for reliable handling and straightforward mounting on many common mini bike and go kart builds. This option is suitable for hobbyists looking to refresh wheel performance without committing to a full axle assembly.
Compatibility notes: verify your mini bike’s axle diameter and hub spacing before ordering. The V-tread provides improved grip for mixed-use environments and can contribute to a more stable driving experience on uneven terrains.
Mini Bike Rear Wheel Assembly Kit, 145×70-6
This assembly kit pairs 145×70-6 tires with a 6″ rear rim to fit a wide range of mini bikes and go-karts. The wheelset supports a maximum load of around 165 pounds, making it suitable for many hobby class rides and simple builds. The V-shaped tread design aids traction, particularly on wet surfaces, while the premium rubber compound offers durability for everyday use. It is compatible with various brands including Coleman, Motovox, Baja, and Massimo, catering to popular mini bike and go-kart models with a 12 mm axle.
Considerations: ensure your frame accommodates a 6″ rim and matches the axle diameter. The kit’s tread design and construction are intended for reliable performance across mixed terrains and routine driving sessions.
Buying Guide: Key Purchase Considerations
When selecting a go kart rear wheel or kit, consider the following factors to optimize performance and compatibility:
- Wheel and tire size: confirm diameter, width, and overall tire profile to match your frame clearance and ground clearance requirements.
- Axle and hub compatibility: check axle diameter (commonly 12 mm) and hub spacing to ensure a proper fit with your chassis and drive system.
- Drivetrain integration: determine whether you need a full brake assembly, sprocket, chain, or only tires and rims. For builds requiring braking, choose a kit with compatible brake components.
- Tubeless vs tubed tires: tubeless designs reduce maintenance and offer a smoother ride, but require proper seating and bead seating on compatible rims.
- Terrain suitability: tread pattern (V-shaped vs other designs) affects traction on wet vs dry surfaces. Consider where you’ll ride most often (dirt, pavement, mixed terrain).
- Load capacity: verify weight limits of the wheel kit to ensure it supports the rider plus gear, especially for mini bikes and go-karts designed for younger users.
- Brand and parts availability: choose kits from reputable sellers with readily available replacement parts (brake components, sprockets, tubes, and tires).
Overview comparisons assist in selecting the right option for your build. For a full braking setup and ready-to-mount wheel assembly, consider the complete hub kit with brake components. For lighter updates or replacements, tubeless tires on 6″ rims provide a straightforward upgrade. Always verify compatibility with your frame, axle size, and drive chain configuration before purchasing to ensure a seamless installation and optimal performance.
