- Adjust Control Bar Height: Release the knob on the back of the stem to adjust the height of the steering wheel to your preferred level, then re-tighten the knob.

5. Operating Instructions
5.1 Initial Activation and App Connection
To activate your S-Max and unlock its full potential, download the Segway-Ninebot App on your smartphone. Link your S-Max to your phone via Bluetooth and follow the in-app instructions for activation. The app will guide you through safety instructions and a new rider tutorial.
- If you skip the new rider tutorial, the S-Max top speed will be limited to 4.3 mph.

- New Rider Mode: Maximum speed of 6.2 mph. For users gaining confidence.
- Sports Mode: Maximum speed of 12.4 mph. For experienced riders.
5.3 Push Assist/Power-Assist Mode
Utilize the push assist function in the app to easily maneuver the S-Max forward and backward at a walking pace when not riding, requiring minimal effort.
6. Gokart Kit Compatibility
The Ninebot S-Max can be paired with the Ninebot GoKart Kit for an enhanced riding experience. The included straps in the S-Max box are designed to replace the original straps on the GoKart. After removing the steering bar from the S-Max, attach the self-balancing vehicle to the rear of the GoKart by feeding the H-shaped strap under the chassis, coming back on itself, and flipping it up to align the holes. Secure with the provided screws (two for each side). Once the metal brackets of the strap are attached, add the adapter cap on top of the balance wheel and slide it underneath the GoKart. Pull up the straps, feed them through the GoKart, and fold them securely. Finally, plug the cable into the back of the S-Max.
