3. Operating Instructions
3.1. Powering On/Off & Mode Selection
- Power On: Press the power button on the left handlebar control panel once to turn on the bike. The display will illuminate.
- Power Off: Press and hold the power button for a few seconds until the display turns off.
- Mode Selection: Use the mode button (M) on the left handlebar to cycle through the three working modes:
- E (Eco) Mode: Provides minimal electric assistance, ideal for extending battery range. Max speed approx. 9 mph.
- D (Drive) Mode: Offers balanced electric assistance for general riding. Max speed approx. 12 mph.
- S (Sport) Mode: Delivers maximum electric power for faster acceleration and higher speeds. Max speed approx. 15 mph.
3.2. Riding Modes
- Pure Electric Mode: Twist the throttle handle on the right handlebar to engage the motor without pedaling. The bike will propel itself.
- Electric Assist Mode: Begin pedaling, and the motor will provide assistance based on the selected mode (E, D, or S). This mode reduces effort, especially on inclines or long distances.
- Normal Riding Mode: Turn off the power, and the bike functions as a traditional bicycle, relying solely on pedal power.
3.3. Controls
- Headlight: Use the dedicated headlight switch on the left handlebar to turn the front light on or off for visibility.
- Horn: Press the horn button for audible alerts.
- Gear Shifting: The right handlebar features levers for the 7-speed Shimano derailleur. Use the lever to shift up for higher speeds or down for easier pedaling on inclines.
- Brakes: The bike is equipped with front and rear disc brakes. Squeeze the brake levers on the handlebars to slow down or stop. Applying brakes will cut power to the motor.
- Front Fork Lockout: The front fork features a lockout mechanism (blue dial) to either allow suspension travel (OPEN) or lock it (LOCK) for more efficient pedaling on smooth surfaces.
4. Maintenance
4.1. Battery Care
- Charge the battery fully before first use and regularly.
- Avoid completely draining the battery to prolong its lifespan.
- Store the battery in a cool, dry place, away from direct sunlight and extreme temperatures.
- If removing the battery for storage or security, ensure the internal connectors are not exposed to moisture.
4.2. General Maintenance
- Tires: Regularly check tire pressure and inspect for wear or damage.
- Brakes: Periodically inspect brake pads and discs for wear. Ensure brake levers are responsive.
- Chain: Keep the chain clean and lubricated for smooth operation and to prevent rust.
- Fasteners: Check all bolts and screws regularly to ensure they are tight.
- Cleaning: Clean the bike with a damp cloth. Avoid high-pressure washing directly on electrical components.

5. Troubleshooting
If you encounter issues with your DYU Electric Bike C6, consider the following common solutions:
- Bike not powering on: Check if the battery is properly seated and locked, and if it has sufficient charge. Ensure the power button is pressed correctly.
- Motor not assisting: Verify that you are in Electric Assist Mode (E, D, or S) and not Normal Riding Mode. Ensure the battery is charged.
- Difficulty shifting gears: The Shimano 7-speed derailleur may need adjustment. Consult a bike mechanic if issues persist after basic chain lubrication.
- Brakes not effective: Inspect brake pads for wear and ensure cables are properly tensioned.
- Unusual noises: Check for loose components, chain issues, or debris in the wheels or brakes.
For persistent problems or complex repairs, please contact customer support or a certified electric bike technician.
