Basic operating instructions for Weaver++ 

Turning on and off the bike

Dat Bike brings a completely new approach to protecting your vehicle. The bike does not use a physical key, but instead uses a Bluetooth-connected app on your phone or an RFID card to turn the bike on or off.

Using the Dat Bike app on your phone

With the Dat Bike app, when you approach the bike and squeeze the brakes, the bike will automatically turn on. Similarly, when you move away from the bike, it will automatically turn off. The app connects to the bike via Bluetooth, so make sure Bluetooth on your phone is turned on before connecting.

Watch a video tutorial on how to connect with the app here .

Download the Dat Bike app on the App Store ( iOS ) or Google Play ( Android ).

To connect the app to the bike

1. Check the LCD screen of the bike before connecting with the app to see if it is turned off or on.
2. Open the Dat Bike app and select "CONNECT". The app will display nearby Weaver++ bikes.
3. Choose the bike with the corresponding frame number.
4. Enter your password. At this step, you can enter any password of your choice, but if you want to connect multiple phones to the bike, you need to remember to set the same password. However, at any given time, only one phone can be connected to the bike.
5. Select "SEND" to initiate the connection.
6. Place the RFID card perpendicular to the card reader. At this point, the bike's lights or LCD screen will change status (from off to on, or vice versa, depending on their initial state).
7. Once the connection is successful, the bike information will be updated in the app.

Note:

• For subsequent connections, if you want to unlock the bike using the app, simply have your phone near the bike with the app running in the background. Then, turn off the safety switch and squeeze the brake lever to unlock the bike.
• Make sure that the bike you want to connect is not connected to any other nearby phones.

In some cases, due to changes or firmware updates, there may be compatibility issues with existing connections on the phone, resulting in Bluetooth errors and disconnection from the bike. In this case, you need to delete the bike connection in the Bluetooth settings of your phone, restart Bluetooth, enable location services, and reconnect.

Adjusting the distance limit on the app

You can set the distance between your phone and the bike for the bike to automatically turn on or off. For this operation, as the app connects to the bike via Bluetooth, you need to be close to the bike before performing it.

There are 4 distance levels to choose from as below:

• "Near"
• "Moderate"
• "Far"
• "Farther"

If you choose "Near" as the distance level and while riding the bike, the connection is lost, you will need to select a farther distance level. The Bluetooth signal strength may vary for different types of phones, so the appropriate distance level depends on each phone.

Note: For some Android phones, selecting "Far" is recommended to avoid bike shutdown.

Many users sharing one bike

When multiple users share one bike, each person can download the Dat Bike app and connect to the bike. However, at any given time, only one phone can be connected to the bike.

To set up the app for another person to use the bike, you can follow the same installation process as setting up for the first time.

You and other users can have different passwords, but you need to disable Bluetooth or disconnect from the bike before allowing others to connect.

Using an RFID card

Adding an RFID card to the bike

After successfully connecting to the bike using the Dat Bike app, you can add a new RFID card to the bike. However, each bike can store a maximum of 2 cards.

1. Open the Dat Bike app.
2. On the app's main screen, select "SETTINGS".
3. Choose "Add new card".
4. Place the new RFID card on the RFID reader on the bike.
5. Select "Add card".
6. The app will display a notification of successful card addition.

Note:

• Since each bike can store a maximum of two cards, adding more than two cards may overwrite the old cards in use. You may need to check if the old card (if any) is still active or not.
• You can purchase compatible RFID cards (or use smartwatches, tokens, etc.) and add them to the bike. Just make sure the card is compatible with the Mifare 1K 13 standard.

How to start and stop the bike using an RFID card

To start the bike with an RFID card, place the card horizontally perpendicular to the RFID card reader on the bike for about 0.5 seconds (do not slide the card as the reader needs time to recognize the card).

To actively stop the bike

In addition to the methods of starting and stopping the vehicle mentioned above, you can also proactively turn off the vehicle in certain necessary situations without using the RFID card by using the methods below.

1. Press the red safety switch (kill engine) to temporarily turn off the engine (activate this switch whenever you stop the bike temporarily to avoid unintentional throttle touches).
2. Squeeze and hold the brakes, then turn on the left turn signal, wait for the turn signal to blink, then turn on the right turn signal to completely turn off the bike (this function works when the bike is completely stopped, speed is 0 km/h, and after 2 seconds).

(1) High beam, low beam switch
(2) Turn signal switch
(3) Horn switch
(4) Engine kill switch
Press: Temporary engine shutdown

Release: Normal operation of the motorcycle

Change background color for multi-function display

The LCD of the multi-function meter can switch between bright and dark background modes according to user preferences. Follow the steps below to enable this feature.

1. Switch the headlight from low beam to high beam and wait for about 2 seconds.
2. Quickly switch twice to low beam mode (switch from high beam to low beam, then back to high beam, and then back to low beam again, these steps should be done quickly).
3. The multi-function meter will change its background (if it's in dark mode with color, it will switch to black and white, and vice versa).
4. If you want to return to the previous background mode, repeat the above steps after 10 seconds from the last background switch.

Handbrake

Weaver++ is equipped with a handbrake like other two-wheeled vehicles. When using the handbrake, the engine will automatically cut off to ensure safety. When you want to continue moving, simply release the handbrake completely and twist the throttle.

Regen Brake

The engine brake is integrated into the electric throttle. This is a software-related feature, not hardware like traditional handbrakes.

When you want to slow down, gradually release the throttle and the engine will automatically brake. There is no need to use the handbrake anymore. Riding becomes easier and more convenient with just "twist to accelerate - release to decelerate", compared to the "twist to accelerate - release to decelerate - squeeze the brake" steps required on conventional two-wheeled vehicles. This special feature also helps to regenerate power and charge the battery by about 10% every time the throttle is released, increasing the range of travel. Additionally, the lifespan of the brake pads on the motorcycle is extended as they are used less frequently.

Note:

• Twisting the electric throttle will provide energy to the electric motor to move the vehicle forward. The amount of energy supplied to the electric motor is proportional to the angle of the electric throttle twist (the electric throttle has an initial delay to prevent overly sensitive throttle, ensuring safety for the user and increasing the safety of the vehicle).
• When releasing the throttle slowly to its original position, the regenerative braking will be activated. The amount of regenerative braking is proportional to the angle of releasing the electric throttle (the more throttle is released, the stronger the regenerative braking will be).

Charging electric vehicle

Caution

• Improper charging of electric vehicle can result in electric shock, fire, and endanger life.
• Only use the electric charger provided by Dat Bike.
• The accompanying electric charger is for indoor use only.
• Only charge the vehicle in a dry place to avoid electric shock.

Brake Fluid Level Check

Before riding, check the brake fluid level, which should be above the minimum level mark. Add brake fluid if necessary.

* Front and rear brakes.

(1) Minimum level mark

Brake fluid specification:
DOT 3 or DOT 4

Caution
Improper maintenance may result in brake malfunction and pose a danger. Watch out for the following issues:

• Insufficient brake fluid can allow air to enter the system, causing a loss of braking power.
• Clean the brake fluid reservoir cap before removing it. Use the correct DOT 3 or DOT 4 brake fluid from a sealed container.
• Use the specified type of brake fluid, as using the wrong type can cause rubber components to deteriorate and result in leaks.
• Only mix brake fluid of the same type when adding new fluid. Mixing different types of DOT 3 or DOT 4 brake fluid can cause harmful chemical reactions.
• Make sure no water enters the brake fluid reservoir during the fluid replacement process.
• Water can lower the boiling point of the fluid and cause vapor lock in the system.

Note:
Brake fluid can damage painted surfaces or plastic parts. Always clean up spilled fluid immediately.

Brake fluid replacement

Bring your vehicle to Dat Bike for brake fluid replacement at the intervals specified in the maintenance schedule and general lubrication. Brake piston seals and brake hose should also be replaced at the designated intervals or whenever they are damaged or leaking.

• Brake piston seals: Replace every two years.
• Brake hose: Replace every four years.

Chain slack adjustment

Before riding, check the chain slack and adjust it if necessary.

To check the chain slack

1. Park the vehicle on its center stand.
2. Measure the chain slack as shown in the diagram.

Standard chain slack:
A = 20.0 - 30.0 mm (0.79 – 1.18 in)

Cleaning and lubricating the drive chain

The Weaver++ motorcycle is equipped with O-ring sealed chain to increase durability and resistance against wear during operation. To ensure the chain's durability, it needs to be cleaned and lubricated at the designated intervals in the maintenance schedule and general lubrication, especially when riding in dusty or humid conditions.

Basic steps to clean the chain:

1. Remove dirt and debris from the chain using a cloth or brush.
2. Apply a specialized chain cleaner solution to the entire chain.
3. Use a cloth or brush to clean the chain further.
4. Wipe or rinse the chain clean.
5. Apply a specialized chain lubricant to the entire O-ring sealed chain. Steps to remove/install the Weaver++ motorcycle wheel
