4. Operating Instructions
4.1 Charging the Battery
The lithium battery can be charged either directly on the bicycle or by removing it from the frame. Connect the charger to a standard 100-240V AC outlet and then to the battery's charging port. The charging indicator on the charger will show the charging status. Disconnect the charger once the battery is fully charged.
4.2 Riding Modes
Your CMACEWHEEL GW20-NEW offers three distinct riding modes:
- Pedal Assist Mode: The motor provides continuous power assistance as you pedal. This mode extends your range and makes pedaling easier, especially on inclines.
- Full Electric Mode: Simply twist the throttle to engage the motor and propel the bicycle without pedaling. This mode is ideal for quick bursts of speed or when you prefer not to pedal.
- Manual Mode: Ride the bicycle like a traditional bike, using only pedal power. The electric system is disengaged in this mode.
4.3 Multifunction Display
The integrated LCD display provides essential riding information at a glance. Depending on the specific display version (two types are randomly shipped), you can monitor:
- Current Speed
- Battery Level Indicator
- Odometer (Total Distance Traveled)
- Trip Distance
- Pedal Assist Level (if applicable)
Consult the specific display manual (if provided separately) for detailed navigation and setting adjustments.
5. Maintenance
Regular maintenance is crucial for the longevity and safe operation of your electric bicycle. Perform routine checks and cleaning to keep your bike in optimal condition.
- Tire Pressure: Check tire pressure regularly (recommended 20 PSI for fat tires) to ensure proper handling and prevent punctures.
- Brakes: Inspect brake pads for wear and ensure brake levers provide firm and responsive braking. Adjust as needed.
- Chain Lubrication: Keep the chain clean and lubricated to ensure smooth gear changes and prevent rust.
- Fasteners: Periodically check all bolts, nuts, and quick releases for tightness.
- Battery Care: Store the battery in a cool, dry place. If storing for extended periods, charge it to about 50-70% and recharge every 1-2 months.
- Cleaning: Clean the bike with a damp cloth. Avoid using high-pressure washers directly on electrical components.
