Title: Professional Heavy Duty Training Wheels for 16-22" Kids' Multi-Speed Bicycles

Why Choose Our Training Wheels?
Most training wheels on the market only fit single-speed bikes, leaving parents with geared bikes frustrated. Our B0CBX2GX6B series is specifically engineered to bridge this gap. Whether your child’s bike is a 16-inch starter or a larger 22-inch geared mountain bike, our stabilizers provide the perfect fit and rock-solid support.

Key Technical Specifications:
Compatibility: 16", 18", 20", 22" Bikes (Single Speed & Variable Speed)
Bracket Material: 4mm Thickened High Carbon Steel
Wheel Material: High-Quality Anti-Slip Rubber + Durable Hub
Weight Capacity: Up to 120 lbs (55 kg)
Special Feature: Extended arm design to clear derailleurs/gear systems

Safety & Joy Combined:
Learning to ride a bike is a milestone. We’ve optimized our design with enlarged washers and double bearings to prevent sudden bearing failure—a common cause of falls in cheaper models. The vibrant colors (Black, Yellow, Green, Purple) allow your child to personalize their ride while staying safe.

Package Includes:
2 x Heavy Duty Vertical Bracket Arms
2 x Silent Smooth Wheels
Full Mounting Hardware Kit (Shoulder Bolts, Washers, Nuts)
User-Friendly Installation Guide
Warm Note: Before ordering, please measure your bike's rear axle. This product is NOT suitable for bicycles with quick-release hubs. If your bike has a full chain guard that obscures the axle, some modification may be needed.
【UNIVERSAL FIT FOR MULTI-SPEED BIKES】 Specially designed for 16, 18, 20, 22 inch children's bicycles, especially those with variable speeds and derailleurs. Unlike standard training wheels, our extended reinforced brackets provide ample clearance for the gear system, ensuring a smooth ride on most geared bikes. (Note: Not compatible with quick-release axles).
【HEAVY-DUTY REINFORCED BRACKETS】 Safety is our priority. Our stabilizers feature extra-thick high-carbon steel brackets (up to 4mm thickness), which are 30% stronger than regular ones. They are engineered to prevent bending or breaking, supporting riders up to 120 lbs. Give your child the ultimate stability and confidence to master their balance.
【DOUBLE BEARINGS & SILENT SMOOTH RIDE】 Equipped with premium double high-carbon steel bearings, our wheels ensure a whisper-quiet and ultra-smooth rotation. The wear-resistant, anti-slip rubber outer layer provides excellent shock absorption and grip on various terrains, from sidewalks to park paths, making the learning process enjoyable.
【INSTALLATION PREREQUISITES & TIPS】 To ensure a secure fit, please verify that the visible length of the rear wheel axle studs is at least 0.4 inches (10mm). We recommend setting the training wheels about 0.2-0.5 inches off the ground when the bike is upright to help your child develop a better sense of balance.
【EASY INSTALLATION & WORRY-FREE SUPPORT】 The package includes everything you need: 2x Brackets, 2x Wheels, and all mounting hardware with a detailed manual. With our upgraded locking brace, installation is a breeze. If you are unsure about compatibility, simply send us your bike's photo—our professional support team is available 24/7 to assist you.
