4. Assembly and Setup

Your Myatu M0126 Electric Bike comes partially assembled. Follow these steps to complete the assembly:

1. Unpacking: Carefully remove the bike and all components from the packaging. Retain packaging for potential future transport or returns.
2. Handlebar Installation: Attach the handlebar to the stem, ensuring it is centered and tightened securely. Adjust the angle for comfortable riding.
3. Front Wheel Installation: If detached, install the front wheel into the fork dropouts. Ensure the quick-release skewer or axle nuts are properly tightened. Verify the disc brake rotor is correctly seated within the caliper.
4. Pedal Installation: Identify the left (L) and right (R) pedals. The left pedal threads counter-clockwise, and the right pedal threads clockwise. Apply a small amount of grease to the threads and tighten them firmly with a wrench.
5. Seat Post and Saddle Adjustment: Insert the seat post into the frame. Adjust the saddle height so your leg has a slight bend at the knee when the pedal is at its lowest point. Secure the quick-release lever or bolt.
6. Battery Installation: Insert the 36V 10.4Ah lithium battery into its designated compartment on the frame. Ensure it clicks into place and is locked if a locking mechanism is present.
7. Initial Battery Charge: Before your first ride, fully charge the battery. Connect the charger to the battery and then to a power outlet. The charging time is approximately 5 hours.
8. Pre-Ride Checks:
   • Brakes: Squeeze both brake levers to ensure they engage the front and rear disc brakes effectively.
   • Tires: Check tire pressure. Refer to the sidewall of the tires for recommended PSI.
   • Quick Releases: Ensure all quick-release levers (wheels, seat post) are securely closed.
   • Lights: Test the LED headlight and any rear reflectors.

5. Operating Instructions

5.1 Powering On/Off

To power on the e-bike, press and hold the power button on the handlebar control unit. The display will illuminate. To power off, press and hold the power button again.

5.2 Understanding the Display and Controls

The handlebar control unit typically features:

• Power Button: Turns the system on/off.
• Mode Selection Buttons: Allows you to cycle through different assist levels (Low, Mid, High).
• Battery Indicator: Shows the current charge level of the battery.
• Speedometer/Odometer (if applicable): Displays current speed and distance traveled.

5.3 Riding Modes

The Myatu M0126 offers three distinct riding modes:

1. Throttle Pedal (Electric Bike Mode): Engages the motor directly via a throttle control (if equipped). This mode provides full electric power without pedaling.
2. Pedal Assist Mode: The motor provides assistance as you pedal. You can select different levels of assistance (Low, Mid, High) using the control unit. This mode extends your range and makes pedaling easier.
3. Normal Bike Mode: The electric system is off, and the bike operates like a traditional bicycle, relying solely on your pedaling power.

5.4 Shifting Gears

Your e-bike is equipped with a Shimano 21-speed shifting system. Use the shifters on the handlebars to change gears according to terrain and desired effort. Lower gears are for climbing hills, and higher gears are for flat terrain and speed.

5.5 Braking

The e-bike features front and rear disc brakes for reliable stopping power. Apply both brakes simultaneously for optimal control and shorter stopping distances. Avoid sudden, hard braking, especially with the front brake, to prevent skidding.

5.6 Battery Usage and Charging

• Charging: Always use the original charger provided. Charge the battery in a well-ventilated area, away from flammable materials. Do not leave charging unattended for extended periods.
• Storage: If storing the bike for an extended period, charge the battery to 50-70% and store it in a cool, dry place. Recharge every 1-2 months to maintain battery health.
• Range: The stated range of 30-60km can vary based on terrain, rider weight, assist level, and weather conditions.

6. Maintenance

Regular maintenance ensures the longevity and safe operation of your e-bike.

• Cleaning: Clean the bike regularly with a damp cloth. Avoid using high-pressure washers directly on electrical components.
• Tires: Check tire pressure before each ride. Inspect tires for wear, cuts, or punctures.
• Brakes: Regularly inspect brake pads for wear and ensure brake levers operate smoothly. Adjust or replace as needed.
• Chain: Keep the chain clean and lubricated to ensure smooth shifting and prevent rust.
• Fasteners: Periodically check all bolts, nuts, and quick releases for tightness.
• Battery Care: Keep battery terminals clean. Avoid fully discharging the battery frequently.
• Professional Service: For complex repairs or electrical system issues, consult a qualified e-bike technician.

7. Troubleshooting

Here are some common issues and their potential solutions:

• Bike not powering on:
  • Check if the battery is properly installed and charged.
  • Ensure all electrical connections are secure.
• Motor not assisting:
  • Verify that the e-bike is in Pedal Assist or Electric Bike mode.
  • Check battery charge level.
  • Ensure the pedal-assist sensor is clean and unobstructed.
• Brakes feel spongy or ineffective:
  • Inspect brake pads for wear and replace if necessary.
  • Check brake cables for tension and adjust if loose.
  • For hydraulic disc brakes, bleeding may be required by a professional.
• Unusual noises during riding:
  • Check for loose components (e.g., fenders, chain guard).
  • Inspect the chain for dryness or damage.
  • Check wheel spokes for tightness.
