The KingSong 14D is equipped with a built-in lighting sensor, which eliminates the need for manual control of the headlight. This feature ensures that the main headlight automatically turns on when it gets dark and turns off when the surrounding lighting improves. This not only enhances convenience but also improves safety by ensuring you're always visible without having to worry about adjusting the lights yourself. Whether you're riding in the early morning, evening, or through areas with fluctuating light conditions, the system adapts to provide optimal visibility.

The KingSong 14D features a convenient battery level indicator with LED strips on both sides of the wheel. This intuitive display shows you the remaining charge in real-time, so you can easily monitor your battery status while riding. There's no need to stop and open the app to check how much range you have left—just glance at the LED lights to get a quick and clear indication. The LED strips light up in different colors to represent various levels of charge, helping you gauge how far you can go before needing a recharge. This feature adds to the overall convenience and ensures you’re always aware of your battery status, allowing for a more worry-free and efficient ride.

The KingSong 14D is equipped with a wheel lift sensor integrated into the handle. This smart sensor detects when the unicycle is being lifted or carried, automatically adjusting the system to prevent accidental movement or trigger specific actions, such as locking the unicycle in place. It makes carrying the unicycle more convenient and ensures safety when you're not riding. The sensor helps to prevent unintentional acceleration or misbehavior of the unicycle while you're handling it, providing an additional layer of control and stability.
