1. Introduction and Important Safety Information
Thank you for choosing Aairsk. Before using your Aairsk e-bike/scooter, please read this manual carefully. If there is anything you do not understand completely, please contact us.
Please observe traffic regulations, and do not lend your e-bike/scooter to anyone who is unfamiliar with it.
We recommend your e-bike/scooter only be used by a person aged 16 years or older, always supervise children until they are competent riders.
When using any e-bike/scooter, it is important that you stay within safe limits; if you feel as if you are traveling too quickly, you probably are.
Always test your brakes prior to using the e-bike/scooter, and remember the ebike/scooter will not stop as quickly in the wet as it would in the dry!
Always be careful of using the front brake when turning or on slippery surfaces as locking of the front wheel can be dangerous and result in falling off.
Before you use the e-bike/scooter for the first time, please make absolutely certain that it has been correctly assembled. In particular, you must make sure that the pedals, saddle, handlebars and any self-assembled items have been fitted correctly and tightened.
Avoid consuming alcohol before you ride your e-bike/scooter.
If you need to replace your battery, please dispose of it properly.
Above all, enjoy your Aairsk journey, happy cycling!
2. Inspection Before Riding
Perform the following checks before each ride to ensure safety and optimal performance:
- Saddle seat post: Ensure it does not cross the limit line and is locked tight.
- Bell: Check if it rings well.
- Handlebar or Stem: Ensure it is not over the limit line and is locked tightly.
- Front and rear brakes: Verify normal operation, check for rusted wires, and ensure levers are fixed.
- Fender: Check if it hits the tire.
- Battery: Confirm lights are on or off as expected.
- Front brake and rear brake: Ensure they work well and sound good.
- Spokes: Check for cracks or loose spokes.

5. Maintenance
Battery Charging
When the power is low, please use the on-board charger for charging. When the gauge level is shown in yellow, it must be charged before riding.
Charging steps:
- Open the lid of the charging port.
- Insert the power cord into the charging port.
- Then insert the plug into the power socket (the red indicator light is on).
- Disconnect the power supply in time after 5-6 hours (the charging time varies with the ambient temperature, etc.) after being fully charged (the green indicator light is on).
You must connect the charger to the battery first and then plug the charger into the wall socket, otherwise it may cause damage to the charger.
Battery Maintenance
Proper use, charging, and maintenance of the ebike's lithium-ion battery are essential to safety. Improper handling can lead to a risk of fire. Never use a charger other than the one provided with your Aairsk ebike. Always charge the battery in a well-ventilated area, away from flammable materials.
If the battery is placed in the ebike UNUSED, it will slowly consume power. The ebike can be kept unused for up to two months. After a long time of no use, the meter may show that the battery power drops, which is normal.
When the battery is not used for a long period (more than one month), please be sure to remove it from the ebike and charge the battery to a half-full and full state (after discharging the battery, use the charger for 1.5-2 hours). Then, store it in a cool and dry room (the ideal temperature is 5°C/41°F - 25°C/77°F) and charge it to about 80% every two months.
Batteries and chargers should be stored in a clean, dry, ventilated place, away from contact with corrosive substances, fire, and heat sources (must be at least 2 meters away). Keep them away from flammable substances, and disconnect the charger from the battery.
The most suitable storage capacity for the battery is 50%. If the battery is below 10% or above 90%, long-term storage will lead to irreversible capacity degradation of the battery.
Avoid placing the battery in a risky location where a drop could cause uncontrollable damage to the battery, leading to leakage, heat, smoke, fire, or explosion.
Battery & Controller Protection Guidelines
Avoid exposing the battery and controller of the bicycle directly to rainwater or high-pressure water jets to prevent water ingress and potential short circuits.
- Battery protection: Remove and dry thoroughly if submerged, ensuring 48+ hours of air-drying in a ventilated area.
- Controller care: Despite some protection, prolonged immersion risks damage.
- For post-flooding:
- Wipe battery contacts with a dry cloth.
- Clean mud from wiring harnesses and controller gaps.
- Seek professional inspection for water-damaged components.
Note: Never attempt to charge or power on a wet system, as this may trigger hazardous short circuits.
NOTICE
The battery is not a component that can be repaired by users. If any abnormal phenomena occur, please contact the after-sales department for maintenance. Unauthorized dismantling of the battery will void the three-pack policy and may result in battery heating, smoking, fire, or explosion.
