4.1. Powering On/Off

To power on the bike, ensure the battery switch is in the 'ON' position. Then, press and hold the power button on the handlebar display until the screen illuminates. To power off, press and hold the same button until the display turns off.

4.2. Display Functions

The colorful intelligent LCD display provides real-time riding data, including current speed (MPH), battery level, distance traveled (odometer/trip), and pedal assist (PAS) level. Use the '+' and '-' buttons to adjust the PAS level.

4.3. Riding Modes

The ENGWE M20 2.0 offers multiple riding modes:

• Pedal Assist (PAS) Mode: Provides electric assistance as you pedal. The level of assistance can be adjusted via the display. The bike can last up to 162 miles in PAS mode with dual batteries.
• Throttle Mode: Allows you to ride without pedaling by twisting the throttle. The maximum speed in throttle mode is 20 MPH. With dual batteries, the bike can last up to 63 miles in throttle mode.

4.4. Gear Shifting

The bike is equipped with a 7-speed Shimano Tourney derailleur. Use the shifter on the right handlebar to change gears according to terrain and desired speed. Shift smoothly to avoid damaging the chain or derailleur.

The dual headlights and bright taillights enhance visibility. Use the dedicated button on the handlebar to turn the lights on or off. The taillight also functions as a brake light, illuminating brighter when brakes are applied.

4.6. Braking System

The ENGWE M20 2.0 features 203MM hydraulic disc brakes for strong and reliable stopping power. Apply both front and rear brakes simultaneously for optimal braking performance. Hydraulic disc brakes offer sensitive and stable braking even in extreme weather conditions.

5. Maintenance

Regular maintenance ensures the safety and longevity of your electric bike.

• Cleaning: Regularly clean your bike with a damp cloth. Avoid high-pressure washing directly on electrical components.
• Tire Pressure: Check tire pressure before each ride. The 20*4.0" fat tires require specific pressure for optimal performance across various terrains (city, snow, beaches, mountains).
• Brakes: Periodically inspect brake pads for wear and ensure proper brake lever tension. Adjust as needed or consult a professional bike mechanic.
• Chain: Keep the chain clean and lubricated to ensure smooth gear changes and prevent rust.
• Fasteners: Regularly check all bolts and nuts for tightness. Use a torque wrench to ensure they are tightened to the manufacturer's specifications. Over-tightening or under-tightening can lead to damage or safety hazards.
• Battery Care: Always charge the battery fully after each ride. Never leave the battery completely empty for extended periods, as this can damage the battery cells. Store the battery in a cool, dry place.

6. Troubleshooting

If you encounter issues with your ENGWE M20 2.0, refer to the following common troubleshooting tips:

• Bike Not Powering On: Check if the battery is fully charged and properly seated. Ensure the battery's power switch is in the 'ON' position.
• Motor Not Assisting: Verify the PAS level on the display is not set to '0'. Check all electrical connections for looseness.
• Brakes Squealing/Ineffective: Inspect brake pads for wear or contamination. Ensure the brake calipers are properly aligned with the rotors.
• Gears Not Shifting Smoothly: Check for proper chain lubrication. Inspect the derailleur for alignment or damage.
