5. Operating Instructions
5.1 Power On/Off
To power on the bike, ensure the battery is installed and locked. Press and hold the power button on the LCD display unit for a few seconds. To power off, repeat the process.
5.2 LCD Display and Controls
The intelligent LCD display provides real-time information about your ride, including speed, battery level (power bar), Pedal Assist System (PAS) gear, and odometer (ODO). The display buttons allow you to cycle through information and adjust PAS levels.
Figure 5.1: Intelligent LCD Display and handlebar controls.
5.3 Pedal Assist System (PAS)
The PAS provides electric assistance as you pedal. Use the '+' and '-' buttons on the display control to select your desired assist level. Higher levels provide more motor power. The bike features an E-PAS mode for extended range.
5.4 Thumb Throttle
The thumb throttle, located on the handlebar, allows for electric propulsion without pedaling. Apply gentle pressure to engage the motor. Use with caution and only when safe to do so.
5.5 Shimano 8-Speed Gears
Your TESGO Hummer Pro is equipped with a Shimano 8-speed gear system. Use the gear shifter on the handlebar to change gears, allowing you to adapt to different terrains and inclines efficiently. Shift smoothly to avoid strain on the drivetrain.

5.6 Hydraulic Disc Brakes
The bike features hydraulic disc brakes for reliable stopping power. Squeeze the brake levers gently to apply the brakes. Ensure both front and rear brakes are functioning correctly before each ride. The brake levers also feature power-off sensors that cut motor power when applied.
5.7 Battery Charging and Care
To charge the 48V 15AH battery, connect the charger to the battery charging port and then to a power outlet. The battery can be charged on or off the bike. A full charge typically takes approximately 7.5 hours. Avoid overcharging and store the battery in a cool, dry place when not in use.

6. Maintenance
Regular maintenance extends the life of your e-bike and ensures safe operation.
- Cleaning: Clean the bike regularly with a damp cloth. Avoid high-pressure washing directly on electrical components.
- Tire Pressure: Check tire pressure before each ride. Maintain the recommended PSI for optimal performance and safety.
- Brake Inspection: Regularly check brake pads for wear and ensure brake levers provide firm and responsive stopping power. Adjust or replace as needed.
- Chain Lubrication: Keep the chain clean and lubricated to ensure smooth gear changes and prevent wear.
- Battery Care: Charge the battery regularly, even if not in use, to maintain its health. Avoid fully discharging the battery.
- Fastener Checks: Periodically inspect all bolts and fasteners, especially on the folding mechanism, handlebars, and wheels, to ensure they are securely tightened.
