Operating Instructions
4-in-1 Evolution Stages:
- Stage 1 (Parent-Controlled Stroller): For younger children (10+ months). Use the adjustable telescopic parent handle to steer and control the tricycle. The child's feet rest on the central foldable footrests. The five-point harness ensures safety.
- Stage 2 (Assisted Tricycle): As the child grows, the footrests can be converted to pedals. The parent still maintains control via the handle, but the child can begin to practice pedaling.
- Stage 3 (Learning Tricycle): The parent handle can be removed, allowing the child more independence while still benefiting from the backrest and safety features. The child uses the pedals.
- Stage 4 (Independent Tricycle): For older children (up to 36 months/20kg). The backrest can be removed, allowing the child to pedal and steer independently, similar to a traditional tricycle.
Key Features and Controls:
- Adjustable Telescopic Parent Handle: Adjust height from 93 cm to 96 cm for comfortable pushing. Includes a handle for the front wheel free-wheel system, allowing the child to pedal without affecting the tricycle's speed when parent-controlled.
- Five-Point Safety Harness: Always secure your child using this harness. Covers are provided for comfort on arms and crotch.
- Adjustable Seat and Backrest: The seat is comfortable and features a high backrest for support. Both are adjustable to suit your child's size.
- Removable Fabric Seat Cover: For easy cleaning.
- Foldable Sun Canopy/Awning: Provides shade and protection. It is ventilated at the rear.
- Quiet EVA Foam Wheels: 9-inch front wheel and 7.5-inch rear wheels ensure a smooth and quiet ride.
- Rear Brake: Located at the rear wheels for stopping the tricycle.
- Direction Limiter: Helps control the steering range for younger riders.
- Adjustable Belts: Ensure the safety belts are adjusted snugly to your child.
Maintenance
Regular maintenance will extend the life of your Qplay Cosy Tricycle.
- Cleaning:
- Wipe the steel frame and plastic parts with a damp cloth and mild soap.
- The fabric seat cover is removable and can be hand-washed with mild detergent. Allow to air dry completely before reattaching.
- Do not use abrasive cleaners or solvents.
- Inspection:
- Periodically check all screws, bolts, and fasteners to ensure they are tight. Tighten if necessary.
