5. Functions and Key Pad

5.1 Functions

The GZ3 display shows the following information:

• Battery Level
• Speed (average, maximum, current speed)
• Distance (single Trip, total ODO)
• PAS Level
• Error Indication
• Cruise
• Brake
• Headlight Indication

5.2 Control and Setting Items

Key controls and settings include: Power Switch, Light Switch, Walk Mode, Real-time Cruise, Wheel Size Setting, PAS Level PWM Setting, Speed Limit Setting, Auto-Off Setting.

5.3 Display Area

The overall interface is displayed within the first second of startup. Key displayed items include:

• Headlight Status
• Battery Level
• Speed (unit: km/h or mph)
• PAS Status Indication Area

The display calculates riding speed based on wheel size and signals (requires setting magnet numbers for Hall motors).

5.4 Settings

The following settings can be configured:

• P01: Backlight Brightness: (1: darkest; 3: brightest)
• P02: Mileage Unit: (0: km; 1: mile)
• P03: Voltage Class: (24V / 36V / 48V / 60V / 72V)
• P04: Auto-Off Time: (0: never; other values represent time interval in minutes)
• P05: Pedal Assist Level:
  • 0/3 Gear Mode: Gear 1-2V, Gear 2-3V, Gear 3-4V
  • 1/5 Gear Mode: Gear 1-2V, Gear 2-2.5V, Gear 3-4V, Gear 4-3.5V, Gear 5-4V
• P06: Wheel Size: (Unit: inch, Precision: 0.1)
• P07: Motor Magnets Number: (for Speed Test; Range: 1-100)
• P08: Speed Limit: (Range: 0-50km/h, no speed limit if set to 50). The driving speed will be kept constant as the limited value. Error Value: ±1km/h. Note: Values are measured in kilometers.
