Full Speed Upgrade Guide

One of the most frequent questions we get from Ninebot GoKart Pro owners is:

“Can I reach 43 km/h (27 MPH) speed by upgrading only the mainboard to the GoKart Pro 2 version, without replacing the front controller board?”

Attention: In order to ensure full compatibility, all the boards need to be preprogrammed by our engineers before installation!

The short answer: Yes, you can see a noticeable speed increase by upgrading just the mainboard. However, to fully unlock the GoKart Pro 2’s maximum performance and consistently hit 43 km/h (27 MPH), there's more to consider.

Understanding the Two Boards: Mainboard vs. Front Controller Board

Component	Mainboard (Motherboard)	Front Controller Board
Location	Positioned under the seat, inside the main chassis.	Mounted at the front, linked to the steering and throttle.
Main Function	Manages power distribution, speed limits, battery, firmware, diagnostics, and Bluetooth communication.	Translates rider inputs (steering, throttle) to the mainboard; controls acceleration feel.
Firmware Role	Sets speed caps, torque output, app connection, and overall performance protocols.	Governs input response sensitivity, steering calibration, and control communication.
Upgrade Impact	Unlocks higher speed limit (up to 43 km/h or 27 MPH with Pro 2 version), improves overall power output.	Ensures smooth acceleration, precise control, and stable communication with upgraded board.

Mainboard & Front Controller Compatibility Overview

• GoKart Pro Mainboard + GoKart Pro 2 Front Controller:
  Not recommended. The older mainboard may not fully utilize the Pro 2 front controller’s features. Possible firmware mismatches.
• GoKart Pro 2 Mainboard + GoKart Pro Front Controller:
  Works, but not optimal. You'll likely see speed increases up to ~40-41 km/h (25-26 MPH). However, acceleration may feel slightly rough, and minor system errors can occur.
• GoKart Pro 2 Mainboard + GoKart Pro 2 Front Controller:
  Best choice. Full compatibility. Both boards communicate flawlessly, unlocking smooth throttle response, stability, and reliable speeds up to 43 km/h (27 MPH).

Recommended Upgrade Steps

1. Upgrade Your Mainboard to GoKart Pro 2

• Install the Pro 2 mainboard under the chassis.
• Ensure proper wiring connection to the battery, throttle, brake, and Bluetooth module.
• Update to the latest firmware (Pro 2 version) via the Segway-Ninebot app.
• Test ride to check for immediate speed increase and functionality.

2. Upgrade the Front Controller Board (Recommended for Full Performance)

• Replace the front controller with the Pro 2 version.
• Recalibrate throttle and steering through the app or manually.
• Verify error-free operation and smooth acceleration response.

3. Final System Diagnostics

• Run a full system check using the Segway-Ninebot app.
• Inspect error codes and firmware compatibility.
• Test drive to confirm top speed (targeting 43 km/h or 27 MPH), braking performance, and control smoothness.

Final Thoughts: Should You Upgrade Both Boards?

Mainboard-Only Upgrade:
✔️ Budget-friendly
✔️ Quick installation
⚠️ Speed increase possible (~40-41 km/h or 25-26 MPH), but acceleration may be inconsistent. Some firmware mismatch risk.

Mainboard + Front Controller Upgrade:
✔️ Full 43 km/h (27 MPH) speed unlocked
✔️ Stable, smooth acceleration
✔️ No risk of error codes or compatibility issues
👉 Recommended for the best riding experience
