RZEOZU Mini Bike Rear Wheel & 145/70-6 V-Tread Tire, 6" Alloy Rim — 12mm Axle Fit, Durable Traction

RZEOZU's 145/70-6 mini bike rear wheel and V-tread tire is a complete 6" alloy-rim assembly designed to replace worn rear wheels on CT100U-style small bikes and go-karts that use a 12 mm axle.

If you need a dependable rear wheel setup that fits popular 79.5cc–105cc mini bikes and compact go-karts, this RZEOZU assembly combines a rugged 6-inch alloy rim with a 145/70-6 V-shaped tread tire engineered for traction and longevity. The package matches common OEM dimensions—13.58" overall diameter, 128 mm section width, and a 70 aspect ratio—so it swaps in with minimal adjustments on compatible models.

Will this wheel fit my CT100U, Coleman, or similar mini bike?

Yes—this wheel is engineered for many CT100U-style small bikes and off-road micro-vehicles that accept a 6" rear rim and use a 12 mm axle. Confirm your vehicle’s axle diameter and rim size before ordering to ensure correct fitment.

• Compatible models: Coleman CT100U, CC100X, RB100, B100 and similar
• Also fits Motovox MBX10/11/12, Massimo MB100, Baja Doodle Bug DB30 and select Monster/RT100 variants
• Axle requirement: 12 mm diameter
• Rim diameter: 6 inches; overall tire diameter: 13.58 inches

How does the V-shaped tread affect traction and ride feel?

The V-shaped tread pattern channels water and debris while improving bite on loose or damp surfaces, giving more confident handling than a smooth tread. It’s intended to balance traction and rolling resistance for everyday trail and backyard use.

• Tread geometry designed to disperse water and mud
• Improved lateral grip in corners and on uneven ground
• Moderate rolling resistance for reasonable speed and control
• Good all-around choice for mixed surface riding

What materials and construction ensure durability?

The wheel uses an alloy rim for structural strength without excessive weight, while the tire is molded from reinforced rubber compounds to resist cuts and punctures encountered in light off-road use. Together they’re built to handle the routine stresses of mini bike operation.

• Alloy rim resists bending under load and impact
• Premium rubber compound resists abrasion and tearing
• Manufactured to withstand daily riding conditions
• Balanced assembly for consistent performance

What are the exact dimensions and what should I check before installation?

The tire measures 145/70-6: overall diameter 13.58 inches, rim diameter 6 inches, section width about 128 mm with a 70 aspect ratio. Before you install, verify axle thickness, brake or sprocket clearance, and hub type so the wheel aligns and secures properly.

• 145/70-6 tire sizing, 128 mm section width
• Overall diameter: 13.58 inches; rim: 6 inches
• Intended for 12 mm axle applications
• Check sprocket/brake fitment and chain alignment
