Installazione e assemblaggio
Your GYMAX 18-inch Kids Bicycle arrives 95% pre-assembled to simplify the setup process. The remaining assembly typically involves attaching the pedals, handlebars, training wheels, seat, bell, and rear reflector light. All necessary tools are generally included.
1. Attaching the Handlebars
- Inserire l'attacco manubrio nel tubo della forcella.
- Ensure the handlebars are straight and aligned with the front wheel.
- Tighten the stem bolt securely using the provided tool.
2. Installazione dei pedali
- Identify the 'L' (left) and 'R' (right) markings on the pedals.
- Il pedale destro (R) si avvita in senso orario nel braccio della pedivella destra.
- Il pedale sinistro (L) si avvita in senso antiorario nel braccio della pedivella sinistra.
- Stringere saldamente entrambi i pedali con una chiave inglese.
3. Adjusting Seat and Handlebar Height
The bicycle features adjustable handlebar and saddle heights to accommodate growing children. The handlebar can be adjusted between 32 and 33 inches, and the seat height between 24 and 29 inches.
- To adjust the seat, loosen the quick-release lever or bolt on the seat post. Adjust the seat to a height where the child's feet can comfortably touch the ground while seated.
- To adjust the handlebar, loosen the stem bolt and raise or lower the handlebars to a comfortable riding position.
- Ensure all adjustments are securely tightened before riding.

4. Installing Training Wheels
Training wheels provide stability for new riders and can be easily removed once confidence is gained.
- Attach the training wheel arms to the rear axle, ensuring they are securely fastened with the provided nuts and washers.
- Adjust the height so that the training wheels are slightly off the ground when the bicycle is upright, allowing the rear wheel to make primary contact.

5. Attaching Basket and Bell
- Secure the basket to the front handlebars using the provided straps or clips.
- Mount the bell on the handlebar in an easily accessible position for the rider.
Istruzioni per l'uso
1. Controllo di sicurezza prima della corsa
- Freni: Ensure both front and rear handbrakes function correctly. Squeeze the levers to confirm they engage the wheels effectively.
- Pneumatici: Check tire pressure. Tires should be firm.
- Bolts and Quick Releases: Verify all bolts, nuts, and quick-release levers are securely tightened.
- Casco: Always ensure the rider wears a properly fitted helmet.
2. Sistema frenante
This bicycle is equipped with a dual handbrake system, providing independent control over the front and rear wheels for enhanced stopping power and safety.
- The right-hand lever typically controls the rear brake.
- The left-hand lever typically controls the front brake.
- Instruct the rider to apply both brakes gently and evenly to slow down or stop. Avoid sudden, hard braking with the front brake only, as this can cause instability.

3. Utilizzo del cavalletto
To park the bicycle, use the integrated kickstand. Ensure the bicycle is on a flat, stable surface before engaging the kickstand to prevent it from falling over.
Manutenzione
Una manutenzione regolare garantisce la longevità e il funzionamento sicuro della bicicletta.
- Pneumatici: Check tire pressure weekly. Maintain pressure within the range indicated on the tire sidewall. Inspect tires for wear, cuts, or embedded objects.
- Freni: Controllare periodicamente l'usura delle pastiglie dei freni e assicurarsi che i cavi dei freni non siano sfilacciati. Regolare la tensione dei freni secondo necessità per garantire una frenata reattiva.
- Catena: Keep the chain clean and lightly lubricated. Apply bicycle-specific chain lubricant every few weeks, or more often if riding in wet or dusty conditions.
- Bulloni e elementi di fissaggio: Regularly inspect all bolts, nuts, and quick-release mechanisms for tightness. Loose components can affect safety and performance.
- Pulizia: Clean the bicycle with mild soap and water. Avoid high-pressure washing, which can force water into bearings and other components. Dry thoroughly after cleaning.
- Magazzinaggio: Store the bicycle in a dry, covered area to protect it from weather elements.
