4. Operating Instructions
4.1. Switching Between Modes
The trike's versatility allows for easy conversion between its 7 modes. This typically involves removing or adjusting the canopy, push handle, safety guard, and pedals. Refer to the assembly video for specific steps on component removal and attachment.
4.2. Adjusting the Push Handle
The parent push handle is height-adjustable to accommodate different users. Locate the adjustment mechanism on the handle stem, typically a button or lever, and adjust to a comfortable height. The handle can also be rotated 135 degrees for steering control or detached when the child is ready for independent riding.
4.3. Using the Safety Harness
Always secure your child with the 3-point safety harness. Adjust the straps to ensure a snug fit without being too tight. The harness prevents the child from slipping or falling out of the seat.
4.4. Engaging the Rear Wheel Stopper
When the trike is stationary, or when loading/unloading your child, engage the rear wheel stopper. This prevents the trike from rolling. Push down on the lever located near the rear wheels to lock them. Lift the lever to release.
4.5. Folding for Storage
The trike features a quick-fold mechanism for compact storage and transport. Locate the folding latches or buttons on the frame (refer to the assembly video for exact locations). Engage these mechanisms to fold the trike. Ensure all components are properly aligned before folding to prevent damage.


5. Maintenance
Regular maintenance ensures the longevity and safe operation of your AYJOIR 7-in-1 Folding Kids Trike.
- Cleaning: Wipe down the frame and plastic parts with a damp cloth and mild soap. Avoid harsh chemicals. The fabric canopy and seat cushion can be spot cleaned.
- Inspection: Periodically check all screws, bolts, and fasteners to ensure they are tight. Inspect wheels for wear and tear. Ensure the safety harness and buckles are in good working condition.
- Storage: When not in use, store the trike in a dry, cool place away from direct sunlight and extreme temperatures. Utilize its folding feature for compact storage.
- Lubrication: Moving parts, such as wheel axles or folding mechanisms, may benefit from occasional light lubrication with a silicone-based spray to ensure smooth operation.
