The M6C is a wired LCD display and odometer used on electric bikes that operate on a UART2 communication protocol. It provides real-time ride data and system status while drawing power directly from the e-bike system—no internal battery required. This display is typically used as a replacement for a damaged unit or when restoring full functionality on e-bikes that already use a compatible UART2 controller. Key Features• LCD display with speed, trip, and total distance readouts• Battery level indicator and system status display• Assist level display with PAS support• Headlight control indicator• Boost and walk mode support (controller-dependent)• Error code display for system diagnostics• USB-powered operation (no internal battery) Compatibility & Use Notes• Communication protocol: UART2• Supported system voltages: 24V / 36V / 48V / 60V• USB input: 5V / 500mA• Fits handlebars: 22.2mm / 25.4mm / 28.6mm / 31.8mm• Wired display—connector and pin layout must match controller• Not compatible with CAN-bus systems• Not universal—protocol and connector must be verified before installation Service / Ownership ContextIf the display shows an E10 error, this typically indicates a communication issue. Common causes include a protocol mismatch between the display and controller, or a system-level fault involving the controller, motor, or control inputs. Always confirm UART compatibility and connector pinout before installation, and test the system with the bike powered but stationary. Fit & Use Signals• Good fit if your e-bike uses a UART2-compatible controller• Good fit for replacing a failed or damaged display• Good fit for riders who want detailed ride and system data• Not a fit for CAN-bus controller systems• Not a fit if connector or communication protocol does not match
