5. Operating Instructions
5.1 Battery Charging
- Ensure the e-bike is turned off before charging.
- Connect the charger to the charging port on the battery (or remove the battery to charge separately).
- Plug the charger into a standard wall outlet.
- The indicator light on the charger will show the charging status (typically red for charging, green for fully charged).
- Do not overcharge the battery. Disconnect the charger once fully charged.
5.2 Powering On/Off and Display
- To power on the e-bike, press and hold the power button on the LCD display.
- The LCD display will show information such as speed, battery level, pedal assist level, and distance traveled.
- Use the control buttons on the display to adjust pedal assist levels (PAS mode) or to cycle through display information.

5.3 Riding Modes
The ENGWE ENGINE X typically offers multiple riding modes:
- Pedal Assist System (PAS) Mode: The motor provides assistance as you pedal. You can select different levels of assistance (e.g., 1-5) via the display controls. This mode offers the longest range (up to 120KM).
- Electric Mode (Throttle): (If applicable, check local regulations for throttle use). The motor provides power without pedaling, typically controlled by a thumb or twist throttle.
- Manual Mode: Ride the bicycle like a traditional bike without any motor assistance. Use the 7-speed Shimano gears for optimal pedaling efficiency.
5.4 Gear Shifting
The 7-speed Shimano gear system allows you to adapt to various terrains and inclines. Use the shifter on the handlebar to change gears. Shift to lower gears for uphill climbs and higher gears for flat terrain or downhill riding.
5.5 Lights
