4. Operating Instructions

4.1 Powering On/Off

To power on the e-bike, use the NFC key card as instructed. The Smart LCD Display will illuminate.

4.2 Working Modes

The Aairsk GT300 offers three distinct working modes to suit various riding preferences:

• Bicycle Mode: Functions as a traditional bicycle, requiring pedal power without motor assistance. Ideal for exercise or when battery power is low.
• Pedal Assist Mode (PAS): The motor provides assistance as you pedal. This mode features 5 adjustable speed levels (gears) to customize the level of assistance.
• Throttle Mode: Twist the throttle on the right-hand grip to engage motor power without pedaling.

4.3 Smart LCD Display and Controls

The handlebar-mounted Smart LCD Display provides essential riding information and controls:

• Display: Shows current speed, battery level, PAS level, and trip distance.
• Horn/Light Switch: Activates the integrated horn and front light.
• Twist Grip Throttle: Located on the right handlebar, used for throttle mode.
• Shimano 7 Gear Shifter: For manual gear changes.

Pedal Assist (PAS) Levels:

4.4 Gearing System

The Aairsk GT300 is equipped with a Shimano 7-speed derailleur, allowing for smooth and precise gear changes to adapt to various terrains and riding conditions. Use the shifter on the handlebar to select your desired gear.

4.5 Braking System

The e-bike features a sensitive dual disc braking system with 160mm front and rear discs. This provides quick, stable, and powerful progressive braking for enhanced safety in all road conditions.

4.6 Suspension System

The Aairsk GT300 is equipped with an adjustable shock-absorbing front fork and a dual shock absorber system. The front fork features a lockout mechanism, allowing you to stiffen the suspension for efficient pedaling on smooth surfaces or unlock it for comfort on rough terrain. This system effectively reduces bumps and vibrations, contributing to a smoother, safer, and more controllable ride.

5. Battery Information

The Aairsk GT300 is powered by a built-in, removable 36V 10Ah Lithium-ion battery, integrated seamlessly into the lightweight geometry frame.

5.1 Range

The maximum travel range varies depending on the riding mode, terrain, rider weight, and other factors:

• Pure Electric Mode: Approximately 13-15 miles (21-24 km)
• Pedal-Assisted Mode: Approximately 20-40 miles (32-64 km)

Note: Actual range may vary significantly based on usage conditions. Some users report lower ranges, especially in higher power assist modes or hilly terrain.

5.2 Charging

• Use only the original charger provided with your e-bike.
• Connect the charger to the charging port on the bike, then plug it into a power outlet.
• A full charge typically takes approximately 4 hours.
• The battery features built-in protections against over-temperature, over-voltage, over-charging, and full battery outage.
• Ensure the charging environment is safe and well-ventilated.

5.3 Battery Care

• Avoid completely draining the battery.
• Charge the battery regularly, even if the bike is not in frequent use.
• Store the battery in a cool, dry place.
• Do not expose the battery to extreme temperatures.

6. Maintenance

Regular maintenance is crucial for the longevity and safe operation of your Aairsk GT300 E-bike.

6.1 General Bicycle Maintenance

• Tires: Check tire pressure before each ride. Maintain recommended PSI for optimal performance and safety.
• Brakes: Regularly inspect brake pads for wear and ensure brake levers provide firm and responsive stopping power. Adjust as needed.
• Chain: Keep the chain clean and lubricated to ensure smooth gear changes and prevent premature wear.
• Gears: Periodically check and adjust the Shimano 7-speed derailleur for accurate and smooth shifting.
• Fasteners: Ensure all bolts, nuts, and quick releases are tightened to their specified torque settings.
• Cleaning: Clean your e-bike regularly with a damp cloth. Avoid high-pressure washing directly on electrical components.

6.2 E-bike Specific Maintenance

• Battery: Follow battery care guidelines (Section 5.3). Inspect the battery casing for any damage.
• Motor: Keep the motor area clean. Avoid submerging the motor in water.
• Wiring: Periodically check all visible wiring for any signs of wear, fraying, or damage.

7. Troubleshooting

This section addresses common issues you might encounter with your Aairsk GT300 E-bike.

• Motor Power Discrepancy: The e-bike features a 250W nominal motor, with a rated power of 400W and a peak power of 540W. This design allows for higher performance when needed while adhering to legal continuous power limits in some regions.
• Limited Battery Range: If you experience a shorter range than expected, consider the following:
  • Riding Mode: Higher PAS levels or continuous throttle use consume more battery.
  • Terrain: Hilly or uneven terrain significantly reduces range.
  • Rider Weight & Cargo: Heavier loads decrease efficiency.
  • Tire Pressure: Under-inflated tires increase rolling resistance.
  • Temperature: Cold weather can reduce battery performance.
• Motor Assist Delay: Some users have noted a slight delay when the motor engages or disengages in pedal-assist mode. This is generally normal behavior for the system.
• Assembly Issues: If you encounter issues during assembly, such as misaligned brakes or stiff components, refer to the assembly instructions or seek professional assistance. Some users have reported issues with bolts or brake alignment upon delivery.

9. User Tips

Insights from other users to enhance your riding experience:

• Assembly Assistance: While assembly is generally straightforward, some users found it helpful to consult YouTube videos for visual guidance, especially if experiencing difficulties.
• Charging Cable Length: The charger cable might be short for some setups. Consider using an extension cord if needed, as the battery is not easily removable for off-bike charging.
• Battery Performance: It may take some time to get accustomed to the battery's performance and how it affects range under different conditions. Experiment with PAS levels to find the optimal balance for your rides.
• Component Check: Upon arrival, thoroughly inspect all components for any potential issues like rounded bolts or brake alignment, as some users have reported minor quality control variations.
• Legal Compliance: Be aware of local regulations regarding e-bike motor power and speed limits, as the bike's peak performance may exceed limits in some regions.
