The M6C is a color LCD display used on electric bicycles that operate on a UART2 communication protocol. It provides core ride and system information at a glance, including speed, battery status, distance, and assist level, without relying on an internal battery.
This display is typically used as a replacement for a damaged screen or as part of an e-bike build using a compatible UART2 controller and 6-pin wiring.
Key Features
• Color LCD screen with clear, readable layout
• Displays speed, battery level, odometer, and PAS level
• USB port for charging external devices
• Wired display powered directly from the e-bike system
• Compact handlebar-mounted design
Compatibility & Use Notes
• Communication protocol: UART2
• Supported voltages: 24V / 36V / 48V / 60V
• Connector type: 6-pin SM plug
• Designed for electric bicycles with compatible controllers
• No internal battery—powered by the bike system
• Not compatible with CAN-bus systems
• Connector and protocol must match controller exactly
Service / Ownership Context
E-bike displays are controller-specific components. Before installation, verify UART protocol compatibility and confirm the 6-pin connector matches the controller harness. After installation, system functions should be tested with the bike stationary to confirm accurate speed readings, assist level changes, and stable communication.
Fit & Use Signals
• Good fit for e-bikes using UART2 controllers
• Good fit for replacing a damaged or unreadable display
• Good fit if you want basic ride data plus USB charging
• Not a fit for CAN-bus systems
• Not a fit if connector or protocol does not match
