Operating Modes (4-in-1 Growth Stages)
The Radio Flyer 4-in-1 Stroll 'N Trike is designed to evolve with your child's development. Here are the four stages:

Stage 1: Toddler Trike (9 - 18 Months)
In this stage, the trike functions like a stroller, providing maximum safety and comfort for the youngest riders. The child is secured by a 3-point harness and a wrap-around safety tray with a cup holder. The adjustable UV protection canopy shields from the sun, and parents maintain full control with the height-adjustable push handle.

Stage 2: Steering Trike (18 - 24 Months)
As your child grows, the safety tray can be removed, allowing more freedom while still being secured by the 3-point harness. The parent continues to steer the trike using the push handle, guiding the child as they begin to understand steering and movement.

Stage 3: Learn-to-Ride Trike (2 - 3 Years)
At this stage, the 3-point harness and canopy can be removed. The child can now practice pedaling and steering independently, with the parent still providing guidance and stability using the push handle. The adjustable seat can be moved forward to allow the child to reach the pedals comfortably.

Stage 4: Classic Trike (3 - 5 Years)
Once your child is confident and capable of riding independently, the push handle can be completely removed. The trike transforms into a classic tricycle, allowing the child to pedal and steer on their own, fostering independence and active play.

Maintenance
Regular maintenance will ensure the longevity and safe operation of your Radio Flyer 4-in-1 Stroll 'N Trike.
- Cleaning: Wipe down the trike with a damp cloth and mild soap. Avoid abrasive cleaners.
- Inspection: Periodically check all nuts, bolts, and fasteners to ensure they are tight. Tighten as necessary.
- Tire Care: The high-density foam tires are maintenance-free. Avoid sharp objects that could puncture them.
- Storage: Store the trike in a dry place away from direct sunlight and extreme temperatures to prevent material degradation.
Troubleshooting
Here are solutions to common issues you might encounter:
- Loose Parts: If any parts feel loose, identify the corresponding fastener and tighten it securely. Do not overtighten.
- Squeaky Wheels: Apply a small amount of silicone-based lubricant to the wheel axles if squeaking occurs. Avoid oil-based lubricants that can attract dirt.
- Steering Difficulty: Ensure the parent push handle is correctly engaged and all steering connections are secure. If the child is in a learning stage, ensure the parent has control.
- Pedals Not Engaging: Check if the pedal mechanism is properly connected to the front wheel. Some models have a clutch for parent-controlled pushing; ensure it's in the correct position.
