SIAECOSYS CT-22
SIAECOSYS CT-22 is a universal programmable LCD speedometer for electric motorcycles. Unlike SIAECOSYS's SCJ-series TFT displays which talk to the controller via ONE-LIN or CAN BUS protocols, the CT-22 is a Hall-version display — it reads speed directly from a motor/wheel hall pulse sensor, making it controller-agnostic. Works with Fardriver, Sabvoton, Kelly, VOTOL, and any other controller regardless of protocol. Operating voltage 48V-120V pack-direct covers e-scooters through high-voltage e-motos. Shows time, driving distance, speed, voltage, and battery capacity (rough SOC from voltage — no BMS comm). Programmable via the display's own menu (no PC required) for wheel size, pole pairs, battery voltage, and speed limits. Compact rectangular housing (185×90×80mm), 350g net. Note: Zero Motorcycles ships CT-22 units with custom firmware on some production bikes (per HV-LEV Discord).
In brief: E-bike display. From $74 across 2 sellers.
