5. Operating Instructions
Familiarize yourself with the bike's controls before riding.
5.1 Braking System
The bike features a dual braking system for effective stopping:
- Hand Brake: Located on the handlebar, this brake is designed with a short reach for small hands. Squeeze the lever to engage the front brake.
- Coaster Brake: To engage the rear brake, pedal backward. This provides an intuitive stopping method for young riders.

5.2 Riding with Training Wheels
Training wheels provide stability for beginners. Ensure they are adjusted so that the bike is slightly tilted, allowing the child to learn balance gradually. As the child gains confidence and balance, the training wheels can be removed (refer to Section 6.3).

6. Adjustments
The bike is designed to grow with your child through adjustable components.
6.1 Handlebar Height Adjustment
The handlebar height can be adjusted to ensure a comfortable riding posture. Loosen the stem bolt, raise or lower the handlebar to the desired height, ensuring it does not exceed the maximum insertion line, and then securely tighten the bolt.
6.2 Seat Height Adjustment
The saddle height is adjustable to accommodate your child's growth. Loosen the quick-release lever or seat post bolt, adjust the seat so the child can comfortably touch the ground with their toes, and then securely fasten the lever or bolt.
6.3 Training Wheels Removal
Once your child has developed sufficient balance, the training wheels can be removed. Unscrew the bolts securing the training wheels to the rear axle and carefully detach them. Store them safely for future use if needed.
