Setup
Your Ado Air 20 E-Bike comes largely pre-assembled. Follow these steps for initial setup:
1. Unboxing and Initial Inspection
Carefully remove the e-bike from its packaging. Inspect for any visible damage during transit. Retain the packaging for future transport or storage.
2. Unfolding the E-Bike
- Place the folded bike on a flat surface.
- Release the frame folding latch, typically located in the middle of the main frame tube. Carefully unfold the frame until it locks into place. Ensure the latch is fully engaged and secured.
- Release the handlebar stem folding latch and raise the handlebar stem until it locks upright. Secure the latch.
- Adjust the handlebar height using the quick-release lever on the stem.
- Adjust the seat post height using the quick-release lever on the seat tube. Ensure the seat post is inserted past the minimum insertion mark.
- Unfold the pedals if they are foldable.

3. Battery Charging
Before your first ride, fully charge the battery. The battery is integrated into the frame. Locate the charging port, typically on the side of the frame. Connect the charger to the port and then to a power outlet. The indicator light on the charger will change (e.g., from red to green) when fully charged. Disconnect the charger once charging is complete.
Note: Use only the original charger provided with your e-bike.
Operating the E-Bike
1. Powering On/Off
To power on the e-bike, press and hold the power button on the handlebar display until the screen illuminates. To power off, press and hold the same button until the display turns off.
2. Pedal Assist System (PAS)
The Ado Air 20 features a torque sensor-based pedal assist system. This means the motor provides assistance proportional to your pedaling effort. The more force you apply to the pedals, the more assistance the motor provides.
- Use the '+' and '-' buttons on the display to cycle through different assist levels (e.g., 0-3 or 0-5).
- Level 0: No motor assistance (pure pedal power).
- Higher levels: Provide more motor assistance, making pedaling easier, especially uphill or against wind.
3. Braking
Your e-bike is equipped with hydraulic disc brakes for superior stopping power. Apply both brake levers simultaneously for effective and controlled braking. Avoid sudden, hard braking, especially at high speeds or on slippery surfaces.
4. Folding for Transport/Storage
To fold the e-bike for transport or storage, reverse the unfolding steps:
- Lower the seat post to its lowest position.
- Fold the pedals if they are foldable.
- Release the handlebar stem latch and fold the handlebar down. Secure the latch.
- Release the main frame folding latch and carefully fold the frame in half. Ensure the latch is secured once folded.

5. App Connectivity
The Ado Air 20 supports app connectivity. Download the official A Dece Oasis app from your smartphone's app store. Follow the in-app instructions to pair your e-bike. The app may provide features suchs as ride tracking, battery status, and customizable settings.
Maintenance
Regular maintenance ensures the longevity and optimal performance of your e-bike.
1. Cleaning
Clean your e-bike regularly with a damp cloth and mild soap. Avoid using high-pressure washers directly on electrical components, motor, or battery. Dry thoroughly after cleaning.
2. Tire Pressure
Check tire pressure before each ride. Maintain the recommended PSI (pounds per square inch) indicated on the tire sidewall. Proper tire pressure improves efficiency, handling, and prevents punctures.
3. Brake Checks
Regularly inspect brake pads for wear and ensure brake levers provide firm and responsive braking. If you notice reduced braking performance, consult a qualified bicycle mechanic.
4. Carbon Belt Care
The carbon belt drive is designed to be maintenance-free for up to 30,000 km. Unlike traditional chains, it does not require lubrication. Keep it clean from excessive dirt or debris. If you notice any unusual noise or wear, consult a professional.
5. Battery Care
- Charge the battery regularly, even if not in use, to maintain its health.
- Store the battery in a cool, dry place, away from direct sunlight and extreme temperatures.
- Avoid fully discharging the battery frequently.
- If storing for an extended period, charge the battery to 50-70% capacity.
