Unfolding the Trike

  2. Press the release button (usually located near the front wheel or frame hinge) and gently pull the frame apart until it locks into place.
  3. Extend the parent control bar and adjust it to your desired height.
  4. Ensure all locking mechanisms are securely engaged before placing a child in the trike.

Securing Your Child

  1. Always ensure the 5-point harness is properly fastened and adjusted to fit your child snugly.
  2. The padded armrest should be in place for additional security, especially for younger children.
  3. For younger children, ensure the footrest is deployed and their feet are comfortably placed.

Operating Instructions

Parent Control Bar

The adjustable parent control bar allows you to steer the trike and guide your child. It features a dual-steering system, enabling you to override the child's steering when necessary. To engage or disengage parent steering, refer to the mechanism located near the base of the parent handle.

Pedals and Footrest

The Liki Trike S3 features interchangeable pedals and a footrest. For younger children (Parent/Push Mode), the footrest should be used. As your child grows and develops motor skills (Tricycle/Bike Mode), the footrest can be folded away, and the pedals can be engaged. Ensure pedals are securely locked in place when in use.

Folding the Trike for Storage/Transport

To fold the trike, ensure the parent control bar is fully retracted. Locate the folding buttons/levers on the frame (typically near the front wheel and main frame hinge). Press and hold these buttons while gently collapsing the trike until it locks into its compact folded position. This compact size allows it to fit in most car trunks and airplane overhead bins.

Maintenance

Regular maintenance ensures the longevity and safe operation of your Liki Trike S3.

  • Cleaning: Wipe down the frame with a damp cloth and mild soap. The fabric components (seat cover, canopy) can be spot cleaned or hand washed with mild detergent. Do not use abrasive cleaners.
  • Inspection: Periodically check all screws, bolts, and locking mechanisms to ensure they are secure. Inspect wheels for wear and tear.
  • Storage: Store the trike in a dry, cool place away from direct sunlight when not in use to prevent material degradation.
  • Canopy Care: The UPF 50+ water-repellent canopy should be cleaned gently to maintain its protective properties.

Troubleshooting

If you encounter issues with your Liki Trike S3, consider the following:

  • Difficulty Folding/Unfolding: Ensure all components are aligned correctly and release buttons are fully pressed. Do not force the mechanism.
  • Loose Parts: Check all screws and connections. Tighten any loose fasteners. If a part is broken or missing, contact customer support.
  • Steering Issues: Verify that the parent control bar's steering engagement mechanism is correctly set for either parent or child control.
  • Child Discomfort: Re-adjust the harness, backrest recline, and footrest/pedal position to ensure a comfortable and secure fit for your child's age and size.
