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 Context
If 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
