The WATT Brooklyn is an e-bike, and this manual provides comprehensive instructions for its operation, maintenance, and troubleshooting. The core of the e-bike's user interface is its display, which provides essential information and allows for control over various functions.

Function Description

The WATT Brooklyn is an electric bicycle designed to assist riders with a motor, enhancing the cycling experience. The display serves as the central control unit, showing real-time data and allowing the user to interact with the e-bike's electronic systems.

Usage Features

Display Overview:

The display shows several key pieces of information:

• SPEED: Current riding speed.
• TRIP: Distance covered in the current trip.
• ODO: Total accumulated distance (odometer).
• Km/h: Unit for speed and distance.
• LIGHT: Indicator for the rear light.
• Battery indicator: Shows the current charge level of the battery.
• LEVEL: Indicates the current support level from the motor.

Power ON/OFF:

To turn the e-bike's display and controller on or off, press and hold the "M" button for a few seconds. When the power is off, the display consumes no power. The e-bike is designed to automatically power off after 10 minutes of inactivity to conserve battery.

Mode Selection:

When the display is on, the default mode is "Current Speed." Pressing the "M" button cycles through the other modes in the following order: Current Speed → TRIP → ODO. If the current speed is above 0 km/h, the display will automatically return to "Current Speed" after 2 seconds.

Resetting TRIP Mode:

To reset the "TRIP" distance, navigate to the "TRIP" mode using the "M" button. Once in "TRIP" mode, press and hold the "M" and "DOWN" buttons simultaneously for 5 seconds. The "TRIP" distance will then reset automatically.

Rear Light Control:

The rear light can be turned on or off by briefly pressing and holding the "UP" button.

PUSH Assistant:

For assistance when pushing the bike, press and hold the "DOWN" button. This activates the push assist mode, causing the motor to drive the bike at a speed of 6 km/h.

Support Level Adjustment:

The motor's assistance level can be adjusted using the "UP" and "DOWN" buttons. There are 5 support levels, with Level 1 providing the lowest output power and Level 5 providing the highest. The standard default level is Level 1.

Battery Indicator:

The battery indicator shows the remaining charge. When the battery is full, all five segments of the indicator are illuminated. As the battery level decreases, fewer segments are shown. When the battery is low, no segments are illuminated, and the indicator flashes.

Settings Access:

To access the e-bike's settings, press and hold the "UP" and "DOWN" buttons simultaneously for 2 seconds. To exit the settings menu, press the "MODE" button.

Speed Limit and Wheel Size Configuration:

Within the settings, the first adjustable parameter is the speed limit. Use the "UP" or "DOWN" buttons to select the desired speed limit (up to 25 km/h), then press "MODE" to confirm and move to the next setting. The settings cycle in the order: Speed Limit (km/h) → Wheel Size (inch) → Speed Limit.

The wheel size can also be configured. Optional wheel sizes include 16, 18, 20, 22, 24, 26, 700C, and 28 inches. The default wheel size is 26 inches. Use the "UP" or "DOWN" buttons to change the wheel size, and then press "MODE" to confirm your selection.

Maintenance Features

Display Precautions:

• Avoid physical impact: The display screen should be protected from bumps or shocks to prevent damage.
• Waterproofing: Do not remove the waterproof film attached to the screen, as this could compromise its waterproofing capabilities.

Error Codes and Troubleshooting:

The display is equipped to show error codes if the system encounters a malfunction. When an error code is displayed, the e-bike will not operate correctly until the underlying problem is resolved. The manual provides a table of common error codes, their meanings, and potential solutions:

• Error Code 21 (Abnormal Current): Check if the motor phase is short-circuiting.
• Error Code 22 (Abnormal throttle): Verify that the throttle is not in its active state.
• Error Code 23 (No-phase state): Check if the phase wire is normal and firmly connected with controllers.
• Error Code 24 (Abnormal Hall Signal):
  • For controllers without hall sensors: Check if the phase wire is normal.
  • For controllers with hall sensors: Check if the hall wire is normal.
• Error Code 25 (Abnormal brake): Ensure that the brake is not being applied.
• Error Code 30 (Abnormal Communication): Check if the display and controller are properly connected.

If an error code persists or if you are unable to resolve the issue, it is recommended to contact your local e-bike supplier for repair or replacement. In cases where no solution is found, contact WATT directly.
