Kukirin g4&Teewing GT4 NO DASHBOARD

🚀 Stealth Handlebar & Voltage Monitor Mod: KuKirin G4 / Teewing GT4

Modification by Kozlov

Upgrade your ride by removing the bulky stock dashboard and the weak integrated headlight. This mod allows you to achieve a "clean" handlebar setup, making room for custom MTB handlebars, stems, and other modifications that were previously blocked by the stock plastic housing.
 

[!WARNING] DISCLAIMER: You are solely responsible for any modifications made to your vehicle. If you are not confident in your technical skills, please consult a professional. Ride safe!

🌟 Key Benefits

• Clean Cockpit: Visual aesthetics and complete freedom to install custom stems or accessories.
• Precise Battery Monitoring: The voltmeter provides a real-time, accurate reading of your remaining battery voltage. No more guessing with the unreliable stock "battery bars."
• Easy Maintenance: Gain direct access to your stem bolts. Tighten or adjust your handlebars without disassembling the entire plastic dash.
• OEM Reliability: This mod uses your original internal PCB. No need for expensive third-party controllers or complex rewiring.
• Fully Functional: Your key switch, throttle, and rear lights remain 100% operational.

📦 Requirements

1. 3D Printed Parts: Front and Rear covers (Files included).

2. Electronics: Original dashboard PCB and a Digital Voltmeter (Optional, 0-100V range).

   
   Diameter: 33.5 mm (1.32 in)

3. Donor Parts: Original wire from the button panel (turn signals/horn) to use as a connector.

   

4. Tools: Phillips screwdriver, heat shrink tubing, and basic soldering/crimping tools.

🛠 Step-by-Step Installation

Step 1: Preparation

• Print the covers. Recommended Material: PLA&PETG or ASA (for UV and heat resistance).

• Disassemble the stock plastic dashboard. Carefully remove the internal PCB after disconnecting all plugs.

  

Step 2: Front Panel Mounting

• Place the throttle wire into the dedicated cutout on the Front Cover.
• Slide the Front Cover into place directly under the key switch. Note: The cutout must face UP. Press it firmly against the frame.

Step 3: Wiring & Testing

• Reconnect the main power, throttle, and key switch to the original PCB.

• Test: Turn the key. Ensure the red LED on the PCB lights up and the throttle/rear lights respond correctly.
   

  

Step 4: Final Assembly

• Carefully tuck the "spaghetti" of wires and the PCB between the two metal plates of the frame. You may need to tilt the PCB slightly to save space.
• Snap the Rear Cover into place using the integrated clips.

⚡️ Voltmeter Installation (Recommended)

For a precise understanding of your battery's health:

1. Donor Wire: Cut the wire from the old button panel, keeping the 5-pin connector.
2. Wiring Diagram: * Red wire (Voltmeter) ➔ Yellow wire (Connector).

   • Black wire (Voltmeter) ➔ Black wire (Connector).

     

3. Insulation: Use heat shrink tubing on all connections to prevent shorts.

4. Connection: Plug the connector into the "Headlight" port on the PCB.
    

   

5. Operation: The voltmeter will now turn on when you activate the lights or turn the key (depending on your configuration).

📊 Voltage Cheat Sheet (60V System)

Check your voltmeter against these values to know your real range:

• 67.2V — 100% (Fully Charged)
• 59.2V — 50% (Halfway Point)
• 48.0V - 50.0V — 0% (BMS Cut-off / Charge Immediately)
