4. Setup

4.1. Assembly

Your MBM E-Pulse U 28' SR11 electric bicycle comes partially assembled. Follow these steps to complete the assembly:

1. Handlebar Installation: Insert the handlebar stem into the fork steerer tube and tighten the bolts securely. Ensure the handlebar is straight and aligned with the front wheel.
2. Pedal Attachment: Identify the left (L) and right (R) pedals. The left pedal tightens counter-clockwise, and the right pedal tightens clockwise. Apply a small amount of grease to the threads and tighten firmly with a wrench.
3. Seat Post and Saddle: Insert the seat post into the frame's seat tube. Adjust the saddle height for comfortable pedaling with a slight bend in your knee at the bottom of the pedal stroke. Tighten the quick-release or bolt securely.
4. Front Wheel (if detached): If the front wheel is not pre-installed, attach it to the fork dropouts, ensuring the quick-release or axle nuts are tightened properly.

4.2. Initial Battery Charge

Before your first ride, fully charge the battery. Connect the charger to the battery charging port and then plug it into a standard wall outlet. The indicator light on the charger will typically change from red to green when fully charged. This may take several hours.

5. Operating Instructions

5.1. Power On/Off

To power on the electric system, press and hold the power button on the LCD display unit. To power off, press and hold the same button until the display turns off.

5.2. Pedal Assist Levels

Your MBM E-Pulse U 28' SR11 features 5 levels of pedal assist. Use the '+' and '-' buttons on the control panel to cycle through the assist levels. Level 1 provides minimal assistance, while Level 5 provides maximum assistance. The motor will only engage when you are pedaling.

5.3. Gear Shifting

The bicycle is equipped with a Shimano TX 50 7-speed shifter. Use the shifter on the handlebar to change gears. Shift to a lower gear for easier pedaling on inclines and a higher gear for faster speeds on flat terrain. Always ease off the pedals slightly when shifting to ensure smooth transitions.

5.4. Braking

The bicycle uses V-Brake Black Alloy brakes. The right lever controls the rear brake, and the left lever controls the front brake. Apply both brakes simultaneously for effective stopping power. Avoid sudden, hard braking with the front brake only, especially at high speeds, to prevent loss of control.

5.5. LCD Display

The LCD display shows important information such as current speed, battery level, pedal assist level, and trip distance. Refer to the separate display manual (if provided) for detailed functions and settings.

Regular maintenance is essential for the safety and performance of your e-bike.

6.1. Cleaning

Clean your bicycle regularly with a damp cloth and mild soap. Avoid using high-pressure washers directly on electrical components, bearings, or seals.

6.2. Battery Care

• Charge the battery fully after each ride.
• If storing the bike for an extended period, charge the battery to 50-70% and store it in a cool, dry place. Recharge every 2-3 months.
• Do not expose the battery to extreme temperatures.

6.3. Tire Pressure

Check tire pressure before each ride. Maintain the pressure recommended on the tire sidewall for optimal performance and to prevent punctures.

6.4. Brake Adjustment

Periodically check brake pad wear and cable tension. Adjust as necessary to ensure effective braking. If you are unsure, consult a professional bicycle mechanic.
