Easy Assembly: Install onto the rear axle using a wrench; adjust the height to make the main wheel vertical. Easy installation, ready for quick use. Universal Compatibility: Suitable for 16-inch, 18-inch, 20-inch, 22-inch, and 24-inch children's bicycles. Also compatible with geared bicycles—special extension screws are required for this.
