• To power off, press and hold the 'M' button again.

4.2 S900 LCD Display Functions

The S900 LCD display provides real-time riding data:

• Speed: Current riding speed.
• ODO: Total odometer reading.
• TRIP: Trip odometer (resets when powered off).
• Battery Level: Indicates remaining battery charge.
• PAS (Pedal Assist System): Shows current assist level (0-5).
• Mode: Displays current riding mode (ECO, STD, POWER).

4.3 Riding Modes

Your ECOTRIC bike offers four distinct riding modes:

1. Pedal Assist Mode: The motor provides assistance as you pedal. Adjust the PAS level (1-5) using the '+' and '-' buttons on the control panel. Higher levels provide more assistance.
2. Fully Electric Mode: Twist the throttle on the right handlebar to engage the motor without pedaling. The speed will correspond to the current PAS level.
3. Pedal Mode: Ride the bicycle like a traditional bike with no motor assistance. Set PAS to 0.
4. Booster Mode: The e-bike will travel at 6 km/h (3.73 mph), useful for walking alongside the bike.

4.4 Gear Shifting

The bike is equipped with a SHIMANO 7-speed drivetrain. Use the shifter on the right handlebar to change gears. Push the '+' button for higher gears (faster speed) and the lever for lower gears (easier pedaling).

5. Battery and Charging

Your ECOTRIC electric bike is powered by a 36V/12.5AH removable lithium battery.

• Charging Time: Approximately 6-8 hours for a full charge.
• Range: 30-54 KM (18.64-33.55 miles) per charge, depending on usage of pedal assist vs. throttle.
• The battery can be charged while installed on the bike or removed for convenient charging indoors.

6. Maintenance

Regular maintenance ensures optimal performance and longevity of your electric bike.

6.1 Tire Pressure

• The 26"x4.0" fat tires have a maximum pressure of 20 PSI.
• For a smooth ride on varied terrain, 18 PSI is generally recommended. Adjust based on riding conditions and personal preference.

6.2 Brake Adjustment

The bike is equipped with disc brakes. If you notice rubbing or reduced braking performance:

• Loosen the caliper mounting bolts slightly.
• Squeeze the brake lever to center the caliper over the rotor.
• While holding the lever, re-tighten the mounting bolts.
• Adjust the cable tension using the barrel adjuster on the brake lever or caliper if needed.

6.3 Derailleur Adjustment

If shifting is not smooth, adjust the derailleur cable tension using the barrel adjuster on the shifter or the derailleur itself. Turn clockwise to loosen tension, counter-clockwise to tighten.

6.4 Suspension Adjustment

• The front suspension fork has a lockout feature (red dial) to stiffen the fork for smooth terrain.
• The other side of the fork has an adjustment dial to control the stiffness of the suspension. Turn clockwise for a stiffer ride, counter-clockwise for a softer ride.

8. Troubleshooting

Here are solutions to common issues you might encounter:

• Shifting Issues: If gears are not shifting smoothly, the derailleur cable may have stretched. Adjust the barrel adjuster on the shifter or derailleur to increase cable tension.
• Brakes Rubbing: If the disc brakes rub, follow the brake adjustment steps in the Maintenance section to re-center the caliper.
• Battery Not Charging: Ensure the charger is properly connected to both the battery and a power outlet. Check the battery lock position.
• Display Not Turning On: Verify the battery is securely locked in place and has sufficient charge. Check all cable connections to the display.
