3. Operating Instructions
Your ANCHEER Electric Mountain Bike offers four distinct working modes to enhance your riding experience:
- PAS Mode (Pedal Assist): The motor provides a moderate amount of power as you pedal. You can select from 1 of 5 pedal assist levels to match your desired effort and terrain.
- Throttle Mode: Engage the throttle to achieve speeds up to 22 MPH. The LCD display allows you to switch between 1-5 levels of throttle power.
- Cruise Mode: Maintain a fixed speed of 10 km/h by long-pressing the "-" key for three seconds. This mode is ideal for consistent cruising on flat paths.
- Pure Pedal Mode: Ride the bike like a traditional bicycle without any electric assistance.
The integrated LCD display provides crucial riding data:
- Battery Level
- Selected Pedal Assist Level (1-5)
- Current Speed (MPH & KMH)
- Total Mileage

4. Maintenance
Regular maintenance is crucial for the longevity and safe operation of your electric bike. Perform these checks periodically:
- Battery Care: Charge the battery regularly, even when not in use, to maintain its health. Avoid fully discharging the battery. Store in a cool, dry place.
- Tire Pressure: Check tire pressure before each ride and inflate to the recommended PSI indicated on the tire sidewall.
- Brakes: Inspect brake pads for wear and ensure brake levers provide firm and responsive stopping power. Adjust as needed.
- Chain Lubrication: Keep the chain clean and lubricated to ensure smooth gear changes and prevent rust.
- Fasteners: Periodically check all bolts, nuts, and quick releases to ensure they are securely tightened.
- Cleaning: Clean the bike with a damp cloth and mild soap. Avoid high-pressure washing directly on electrical components.
