3. Setup and First Use

3.1 Initial Assembly

Your Aairsk XT90 e-bike comes partially assembled. Follow these general steps to complete the setup:

1. Handlebar Installation: Attach the handlebar to the stem, ensuring it is centered and tightened securely.
2. Pedal Installation: Identify the left (L) and right (R) pedals. The left pedal screws counter-clockwise, and the right pedal screws clockwise. Apply a small amount of grease to the threads if available, then tighten firmly.
3. Front Wheel Installation: If the front wheel is not pre-installed, carefully align it with the front fork and secure it using the quick-release skewer or axle nuts. Ensure the brake rotor is correctly seated within the caliper.
4. Seat Post Adjustment: Insert the seat post into the frame. Adjust the seat height to a comfortable riding position where your feet can touch the ground when stopped, or your leg is slightly bent at the knee when the pedal is at its lowest point. Secure the quick-release clamp firmly.
5. Pre-Ride Checks: Before your first ride, perform all checks listed in Section 4.1.

3.2 Battery Charging

It is crucial to fully charge the battery before your first use to ensure optimal performance and battery longevity.

1. Ensure the e-bike is turned off.
2. Connect the charger to the charging port on the e-bike's frame.
3. Plug the charger into a standard power outlet.
4. The charging indicator on the charger will show the charging status (e.g., red for charging, green for fully charged).
5. Charge for approximately 6-7 hours until fully charged.
6. Once fully charged, disconnect the charger from the power outlet first, then from the e-bike.

Important: The built-in battery is detachable but cannot be charged separately from the bike. Always use the original charger provided.

• Fasteners: Regularly check all screws, bolts, and quick-release levers to ensure they are tight.
• Wires & Connections: Inspect all electrical wires and connectors for any signs of wear, fraying, or damage.
• Tires: Check tire pressure regularly and inflate to the recommended PSI. Inspect tires for wear, cuts, or embedded objects.
• Brakes: Check brake pads for wear and replace them when necessary. Ensure brake levers have proper tension and feel.
• Chain: Keep the chain clean and lubricated for smooth gear changes and to prevent rust.
• Storage: Store the e-bike in a cool, dry place, away from direct sunlight and extreme temperatures. If storing for an extended period, ensure the battery is charged to about 50-70% and recharge it every 1-2 months.
