7. Betjeningsvejledning
Your BAFANG Ebike Conversion Kit offers four primary riding modes, allowing you to customize your riding experience. The 500C display provides essential information and control over these modes.

Figur 7.1: Overview of the 500C Smart Digital LCD Display.
7.1 Køretilstande
- Gashåndtag: Engage the thumb throttle to propel the bike without pedaling. The motor provides power directly based on throttle input.
- Pedalhjælpstilstand (PAS): The motor provides assistance as you pedal. The level of assistance can be adjusted via the display (typically 3, 5, or 9 levels). This mode extends battery life and reduces rider effort.
- Walk Assist tilstand: Provides low-speed motor assistance to help you push the bike when walking alongside it. This is useful for navigating crowded areas or steep inclines off the bike.
- Kun pedaltilstand: The motor provides no assistance, and the bike functions as a traditional bicycle.
7.2 Display Operation (500C Exampdet)
The 500C display allows you to monitor your ride data and control kit settings:
- Tænd/sluk: Tryk og hold tænd/sluk-knappen nede for at tænde eller slukke for systemet.
- PAS-niveaujustering: Use the '+' and '-' buttons to cycle through pedal assist levels.
- Informationsdisplay: The screen shows current speed, battery level, power output, trip distance, and total mileage.
- Indstillinger: Access advanced settings (e.g., wheel size, speed limit, password) through the display menu. Refer to your specific display's manual for detailed instructions on advanced settings.
