Product information
The S16 features the same fantastic thick metal battery casing that it's big brother the S22 included. Spiked pedals come stock with the unit allowing you to feel more locked in to the unit in various conditions. The strong trolley handle allows you to lift the wheel without worrying damaging the handle or dropping unit in the process. The S16 uses King Song's 5th generation slider system and a 750lb coil shock to provide comfort when riding off-road or on rough terrain.
King Song has provided many useful and fun features on the S16 Pro such as its touch sensor lift switch that is located in the rear of the wheel, a sturdy kickstand, and the 32*32 dot matrix display. If your phone is running low on battery you can charge it using either the USB-C or USB-A ports on the wheel located in the rear of the wheel. The Bluetooth speakers located towards the rear of the wheel allow you to listen to some of your favorite tunes during rides and the RGB lights can pulse to your music. Pre-installed Velcro on the wheel as well as the included power pads allow you to adjust them easily and quickly.
BMS stands for Battery Management System and the one built into the S16 Pro has the all the features you need to be able to monitor your battery health extensively from within the King Song app. The BMS has temperature protection functions so that your batteries do not overheat. Using the King Song app you can monitor each battery cell individually to ensure that your batteries are in good condition. Viewing the voltage of each cell allows you to see if your unit has any dead cells and you can make sure that your batteries are fully charging.
