6. Operating Instructions

6.1 Powering On/Off

To power on the bike, press and hold the power button on the LCD display. To power off, press and hold the same button.

6.2 Riding Modes

The Jasion YC1 offers four riding modes, selectable via the display controls:

• Pedal-Only Mode: Traditional cycling without electric assistance.
• Pedal Assist Mode (PAS): The motor provides assistance as you pedal. There are multiple levels of pedal assist (1-3), with higher levels offering more power. This mode can provide a range of up to 50 miles.
• Throttle Mode: Engage the motor without pedaling by twisting the throttle. This mode offers a range of up to 25 miles.
• Walk Assist Mode: Provides low-speed motor assistance to help push the bike when walking alongside it, useful for inclines or tight spaces.

6.3 Shifting Gears

Use the shifter on the handlebars to change between the 7 available gears. Shift smoothly and avoid shifting under heavy load to prevent damage to the drivetrain.

6.4 Using the Horn and Headlight

The horn and headlight controls are located on the handlebars. Use the horn to alert others to your presence and the headlight for visibility in low-light conditions.

7. Maintenance

Regular maintenance ensures the safety and longevity of your Jasion YC1 e-bike.

7.1 Battery Care

• Charge the battery regularly, even if not in use, to maintain its health.
• Store the battery in a cool, dry place.
• Avoid fully discharging the battery frequently.

7.2 Tire Pressure

Check tire pressure before each ride. Maintain the recommended PSI (pounds per square inch) indicated on the tire sidewall for optimal performance and safety.

7.3 Brake Inspection

Regularly inspect brake pads for wear and brake levers for proper function. Ensure brake cables are not frayed and disc rotors are clean and free of damage.

7.4 Chain Lubrication

Keep the chain clean and lubricated to ensure smooth gear changes and prevent premature wear. Apply bicycle-specific chain lubricant periodically.

7.5 General Cleaning

Clean your e-bike regularly with a damp cloth and mild soap. Avoid using high-pressure washers directly on electrical components.

8. Troubleshooting

Here are solutions to common issues you might encounter:

8.1 Gear Shifting Issues

If gears are not shifting smoothly or the chain is rubbing, the derailleur may need adjustment. Small screws on the derailleur allow for fine-tuning. Refer to the video in Section 6.3 for a visual guide on adjusting the rear derailleur.

8.2 Brake Squealing

Brake squealing can occur due to dirt on the rotors or misaligned calipers. Clean the rotors with disc brake cleaner and ensure the calipers are centered over the rotor. If the issue persists, professional adjustment may be required.

8.3 Reduced Battery Range

Battery range can be affected by terrain, rider weight, riding mode (throttle-only uses more power), and temperature. Ensure the battery is fully charged before each ride. If range significantly decreases over time, the battery may be degrading or require servicing.
