4. Setup

Before your first ride, ensure the following setup steps are completed:

4.1. Initial Battery Charge

1. Locate the charging port on the battery.
2. Connect the charger to the battery and then to a power outlet.
3. Allow the battery to fully charge before first use. The charging indicator on the battery or charger will show completion.
4. Always use the original Prophete charger provided with your E-MTB.

4.2. Seat Height Adjustment

1. Loosen the quick-release lever on the seat post clamp.
2. Adjust the seat height so that your leg is slightly bent at the knee when the pedal is at its lowest point.
3. Ensure the seat post is inserted beyond the minimum insertion mark.
4. Securely close the quick-release lever.

4.3. Handlebar and Stem Adjustment

Ensure the handlebars are aligned with the front wheel and tightened securely. Adjust the angle of the brake levers and shifters for comfortable reach.

4.4. Tire Pressure

Check the recommended tire pressure on the sidewall of your tires. Inflate tires to the appropriate pressure using a bicycle pump. Correct tire pressure improves ride quality and reduces the risk of punctures.

5. Operating Instructions

Operating your Prophete Graveler E-MTB involves understanding its electronic system and mechanical components.

5.1. Powering On/Off (ProKey)

1. Insert the ProKey chip into the designated slot on the E-MTB.
2. Press the power button on the AEG TFT display to turn on the system.
3. To power off, press and hold the power button until the display shuts down. Remove the ProKey for security.

5.2. Using the AEG TFT Display

The display shows vital information:

• Speed: Current riding speed.
• Battery Level: Remaining battery charge.
• Support Level: Indicates the current level of motor assistance (e.g., Eco, Tour, Sport, Turbo). Use the '+' and '-' buttons on the handlebar control unit to adjust.
• Trip Distance/Total Distance: Toggle between trip and total mileage.
• USB Charging: A USB port on the display allows charging of external devices like smartphones from the E-MTB battery.

5.3. Gear Shifting

Your E-MTB is equipped with a 10-speed derailleur system. Shift gears smoothly by using the shifters on the handlebars. The integrated shift sensor briefly cuts motor power during shifts, ensuring a smoother transition and reducing wear on the drivetrain components.

5.4. Suspension Fork Lockout

The Suntour XCR suspension fork features a lockout function. Use the lever on the handlebar to lock the fork for efficient pedaling on smooth surfaces or climbs, and unlock it for comfort and traction on rough terrain.

6. Maintenance

Regular maintenance ensures the safety, performance, and longevity of your Prophete Graveler E-MTB.

6.1. Cleaning

• Clean your E-MTB regularly with a damp cloth and mild soap. Avoid high-pressure washers, especially near electrical components and bearings.
• Dry the bike thoroughly after cleaning.

6.2. Drivetrain Care

• Keep the chain clean and lubricated. Apply bicycle-specific chain lubricant regularly, especially after riding in wet or dusty conditions.
• Check chain tension and wear. A worn chain can damage other drivetrain components.

6.3. Brake System

• Regularly inspect brake pads for wear and replace them when necessary.
• Check brake fluid levels and bleed hydraulic brakes if they feel spongy. This should ideally be done by a qualified bicycle mechanic.
• Ensure brake rotors are clean and free of oil or grease.

6.4. Battery Care and Storage

• Charge the battery regularly, even if not in use, to maintain its health. Avoid fully discharging the battery.
• Store the battery in a cool, dry place, away from direct sunlight and extreme temperatures.
• If storing for an extended period, charge the battery to 50-70% and check its charge every few months.

6.5. General Inspection

• Periodically check all bolts and fasteners for tightness.
• Inspect tires for cuts, wear, and proper inflation.
• Ensure wheels are true and spokes are tensioned correctly.

For complex maintenance or repairs, it is recommended to consult a professional bicycle mechanic.

7. Troubleshooting

This section addresses common issues you might encounter with your E-MTB.

7.1. E-MTB Not Powering On

• Check Battery: Ensure the battery is fully charged and securely inserted into the frame.
