5. Operating Your E-Bike
5.1 Powering On/Off
To power on the bike, press and hold the power button on the display panel. To power off, press and hold the same button until the display turns off.
5.2 Riding Modes
Your ANCHEER e-bike offers three distinct riding modes, selectable via the display panel:
- Electric Mode (Throttle): If a throttle is installed, gently twist it to engage the motor and propel the bike without pedaling. This mode is ideal for effortless cruising.
- Pedal Assist Mode (PAS): This mode provides motor assistance as you pedal. You can select different assist levels (e.g., 1-5) on the display to control the amount of power assistance. Higher levels provide more assistance.
- Manual Mode: With the power off, the bike functions as a traditional bicycle, relying solely on your pedaling power. This mode is suitable for exercise or when the battery is depleted.
5.3 Gear Shifting (21-Speed Shimano)
The 21-speed Shimano gear system allows you to adapt to various terrains and inclines. Use the shifters on the handlebars to change gears smoothly. Shift to a lower gear for climbing hills and a higher gear for flat terrain or downhill riding.
5.4 Braking
The bike is equipped with front and rear mechanical disc brakes for reliable stopping power. Apply both brake levers simultaneously for balanced and effective braking. Avoid sudden, hard braking, especially at high speeds or on slippery surfaces.
6. Maintenance
Regular maintenance ensures the longevity and safe operation of your e-bike.
- Tires: Check tire pressure before each ride. Recommended pressure is usually indicated on the tire sidewall.
- Brakes: Regularly inspect brake pads for wear and replace them when necessary. Ensure brake levers are responsive and cables are not frayed.
- Chain: Keep the chain clean and lubricated to prevent rust and ensure smooth gear changes.
- Bolts and Fasteners: Periodically check and tighten all bolts, nuts, and quick releases, especially on critical components like wheels, handlebars, and seat post.
- Storage: Store the bike in a cool, dry place, away from direct sunlight and extreme temperatures. If storing for extended periods, ensure the battery is partially charged (50-70%) and recharge it every 1-2 months.
6.1 Battery Care
Proper battery care extends its lifespan:
- Always use the original charger provided with your bike.
- Avoid completely draining the battery before recharging.
- Do not expose the battery to temperatures below -4°F (-20°C) or above 113°F (45°C).
- If the battery will not be used for a long time, charge it to 50-70% and recharge every two months.
6.2 Cleaning
Clean your e-bike with a damp cloth and mild soap. Avoid using high-pressure washers directly on electrical components or bearings.
