UKRiver UKC1 (APT)

3.5" IPS color TFT e-bike display made by UKRiver, in the APT (Sabvoton) protocol variant. Shares the same housing and screen as the UART No.2 UKC1 (OMD) but speaks the Sabvoton APT serial protocol on its 5-pin cable, so it works only with Sabvoton SVMC \"-APT\" suffix controllers (and other APT displays like the 750C). It shows speed, battery level, trip data, and assist level on a 24–72V system.
