5. Operating Instructions

5.1. Battery and Charging

The HEZZO M4 features a removable 36V 10.4Ah lithium battery. It can be charged both on or off the bike frame.

• Charging: Connect the charger to the battery charging port and then to a standard power outlet. The indicator light on the charger will show charging status (typically red for charging, green for fully charged).
• Battery Management System (BMS): The integrated BMS protects the battery, increasing its service life.
• Range: A full charge provides an endurance of 30-45 KM (18.64-30.55 miles), depending on the usage of pedal assist versus throttle.
• Removal: Consult the specific mechanism for battery removal, usually involving a key and a latch, to charge it off the bike.

5.2. Powering On/Off and Display

The bike features a backlit color display for monitoring various parameters.

• Power On: Press and hold the power button on the display unit.
• Power Off: Press and hold the power button again.
• Display Information: The display shows speed, range, pedal assist level, distance, battery level, light status, push mode, brake status, and potential malfunctions.

5.3. Riding Modes: Pedal Assist and Throttle

The HEZZO M4 offers flexible riding options with both pedal assist and a throttle.

• Pedal Assist (PAS): This mode provides motor assistance as you pedal. Use the '+' and '-' buttons on the control panel to adjust the assist level. Lower levels provide less assistance, requiring more effort, while higher levels offer significant boost, making hills easier.
• Throttle: The throttle allows you to propel the bike without pedaling. Simply twist the throttle grip to engage the motor. This is useful for quick acceleration or when you prefer not to pedal.

5.4. Gears (Shimano 21-Speed)

The Shimano 21-speed gear system provides a wide range of gearing options for various terrains and inclines.

• Shifting: Use the trigger shifters on the handlebar to change gears. The left shifter controls the front derailleur (3 speeds), and the right shifter controls the rear derailleur (7 speeds).
• Optimal Use: Shift gears smoothly and anticipate terrain changes. Lower gears are for climbing hills, while higher gears are for flat terrain and speed.

5.5. Brakes

The bike is equipped with front and rear mechanical disc brakes for reliable stopping power.

• Operation: Squeeze the brake levers on the handlebar to engage the brakes. The left lever typically controls the front brake, and the right lever controls the rear brake.
• Braking Technique: Apply both brakes simultaneously for controlled stopping. Avoid sudden, hard braking, especially with the front brake, to prevent skidding.
• All-Weather Performance: Disc brakes are designed to perform effectively even in wet conditions.

5.6. Front Suspension

The upgraded hydraulic shock absorber in the front suspension enhances riding comfort.

• Function: The front suspension absorbs impacts from uneven terrain, providing a more comfortable and controlled ride.
• Adjustment: Some suspension forks allow for adjustment of preload or lockout. Refer to the specific fork manufacturer's instructions if applicable.

6. Maintenance

• Cleaning: Clean the bike regularly with a damp cloth. Avoid high-pressure washing directly on electrical components.
• Lubrication: Keep the chain and moving parts of the drivetrain clean and lubricated.
• Tire Pressure: Maintain recommended tire pressure (usually indicated on the tire sidewall) for optimal performance and puncture resistance.
• Brake Inspection: Regularly check brake pads for wear and brake cables for tension. Adjust or replace as needed.
• Battery Care: Store the battery in a cool, dry place and charge it periodically even if not in use to maintain its health.
