KT's best-value color display upgrade. Full-color dot-matrix LCD with all LCD3 features plus USB phone charging (5V), percentage assist mode (C4=2), motor temperature display (C8), and password protection (C9). Thinner, more modern physical design than the LCD3/5. The most popular upgrade from the LCD3 for builders wanting color without the LCD9's integrated throttle. Compatible with all KT controllers.
In brief: E-bike display. Protocols: KT (Kunteng). Built-in phone charger. From $13.
