Assembly Steps:

1. Unpacking: Carefully remove the bicycle and all components from the packaging.
2. Handlebar Installation: Attach the handlebars to the stem. Ensure they are centered and tightened securely to the manufacturer's specifications.
3. Pedal Installation: Install the pedals. Note that pedals are typically left (L) and right (R) specific and thread in opposite directions. Ensure they are fully tightened.

5. Operating Instructions

Understanding how to operate the electric assist system, gears, and brakes is crucial for a safe and enjoyable ride.

Electric Assist System:

• Power On/Off: Use the power button on the LCD display to turn the electric assist system on or off.
• Assistance Levels: The Z898 offers 5 levels of electric assistance. Use the controls on the handlebar to select your desired level. Higher levels provide more assistance but consume battery faster.
• Maximum Speed: The motor provides assistance up to 25 km/h (15.5 mph). Beyond this speed, you will rely solely on pedal power.
• LCD Display: The clear LCD display shows current speed, selected assistance level, battery charge, and other ride data.

Gears:

• Shifting: The 24-speed derailleur system allows you to select appropriate gears for different terrains and inclines. Shift gears smoothly while pedaling to avoid strain on the drivetrain.
• Trigger Shifters: The bicycle is equipped with trigger shifters for precise and easy gear changes.

Brakes:

• Hydraulic Disc Brakes: The Z898 features hydraulic disc brakes for strong and consistent stopping power in various conditions.
• Braking Technique: Apply both front and rear brakes simultaneously for optimal stopping power and control. Avoid sudden, hard braking with only the front brake, especially at high speeds.

Suspension Fork:

• The 80mm travel suspension fork enhances comfort by absorbing shocks from uneven terrain. The hardness of the suspension can be adjusted to suit rider preference and riding conditions.

6. Battery Information

The integrated 504 Wh battery powers the electric assist system. Proper care ensures optimal performance and longevity.

• Capacity: 504 Wh.
• Range: The estimated range is between 35 km and 150 km. This range is indicative and can vary significantly based on factors such as total weight (rider + luggage), selected assistance level, terrain conditions, and weather (e.g., headwind).
• Charging: Use only the charger provided with your bicycle. Connect the charger to the battery and a suitable power outlet. The charging indicator will show the charging status.
• Storage: When storing the bicycle for extended periods, ensure the battery is partially charged (e.g., 50-70%) and stored in a cool, dry place. Avoid fully discharging the battery for long-term storage.

7. Maintenance
