Battery Installation and Charging
- Locate the battery compartment, typically integrated into the frame.
- Insert the battery, ensuring it locks securely. Use the key if provided to lock the battery in place.
- Before your first ride, fully charge the battery. Connect the charger to the bike's charging port and then to a power outlet. The indicator light on the charger will change when fully charged.
- Charging time may vary, but typically takes several hours for a full charge.
Pre-Ride Checks

Operating
Powering On/Off

Riding Modes
The ADO A20+ offers different riding modes:
- Pedal Assist Mode: The motor provides assistance as you pedal. You can adjust the level of assistance (e.g., Eco, Standard, Sport) using the controls on the handlebar. This mode extends your travel range significantly.
- Electric Mode (Throttle): Use the throttle to engage the motor without pedaling. This mode is ideal for quick acceleration or when you need a break from pedaling. Note that the electric range is approximately 40km, while the boost (pedal assist) distance is approximately 80km.
- Manual Mode: Ride the bike like a traditional bicycle without any electric assistance.
Gear Shifting
Utilize the Shimano 7-speed shifter to adjust your gear ratio according to terrain and desired effort. Shift to lower gears for climbing hills and higher gears for flat terrain or downhill riding.
Braking
The bike is equipped with dual disc brakes. Apply both front and rear brakes simultaneously for effective and safe stopping. Avoid sudden, hard braking, especially with the front brake only, to prevent skidding.

Maintenance
Regular maintenance ensures the longevity and safe operation of your ADO A20+ Electric Bike.
- Cleaning: Clean the bike regularly with a damp cloth. Avoid using high-pressure washers directly on electrical components.
- Tires: Check tire pressure before each ride. Maintain recommended pressure for optimal performance and safety.
- Brakes: Inspect brake pads for wear and replace them when necessary. Ensure brake levers are responsive and cables are not frayed.
- Chain: Keep the chain clean and lubricated to ensure smooth gear changes and prevent rust.
- Battery Care: Store the battery in a cool, dry place. If storing for extended periods, charge it to about 50-70% every few months. Avoid fully discharging the battery frequently.
- Fasteners: Periodically check all bolts, nuts, and quick-release levers to ensure they are tight and secure.
