The C800-TFT display serves as the central interface for controlling and monitoring an e-bike. Its primary functions include:
- Riding Mode Selection: Allows users to choose between different riding modes (POWER, STD, ECO) to adjust the e-bike's performance. The default mode is NORMAL.
- ECO Mode: Limits current to approximately 6A, suitable for elderly riders.
- STD Mode: Limits current to approximately 10A, suitable for city riding.
- POWER Mode (referred to as ECO in the manual's description of 15A limit): Limits current to approximately 15A, suitable for young riders and mountain biking.
- Speed Display: Shows the current riding speed.
- KM/H & MPH Selection: Users can select their preferred unit for speed and mileage display.
- Light Indicator: Indicates the status of the e-bike's lights.
- 6KM/H Work (Walk Assist): Provides a walk-assist function at 6 km/h.
- PAS Level Selection: Allows adjustment of the Pedal Assist System (PAS) levels, which control the output power ratio. The default is level 1, with a range from 1 to 5. Modes 3, 6, and 9 can be customized in advanced settings.
