Section 2: Photosensitive Automation & Bluetooth App Connectivity
Automated Environmental Lighting and Wireless Smartphone Control
The LCD135C incorporates smart optical sensors and wireless protocols to elevate safety and user convenience.
***Integrated Photosensitive Light Sensor:** An ambient light sensor built directly into the display face continuously measures environmental illumination.
***Dynamic Screen Dimming:** Automatically adjusts screen backlight brightness to eliminate glare in direct sunlight and prevent night blindness in low-light conditions.
***Automated Headlight Control:** Automatically toggles connected headlights on or off based on external lighting conditions when set to Auto mode.
***Optional Embedded Bluetooth Module:** Connects wirelessly with ToSeven’s dedicated mobile smartphone application (iOS and Android supported).
***Digital Bike Lock:** Allows riders to lock or unlock the e-bike drive system remotely via smartphone authentication.
***Advanced App Features:** Syncs ride logs, displays real-time GPS navigation, tracks historical power curves, and allows custom display theme parameter editing.

Section 3: Riding Modes, Torque Profiles & Setup Menus
Dual-Mode Torque Sensing, Power Profiles, and Secured Configuration
The LCD135C offers tailored performance profiles depending on whether the system is operating in torque-sensing or cadence-sensing mode.
***Torque Sensor Active Riding Profiles:**
***Mode M1 (Torque Mode):** Proportional power delivery reacting directly to physical pedal effort for a natural cycling feel.
***Mode M2 (Cadence / Step Frequency Mode):** Modulates motor output based on pedal cadence RPM for effortless cruising.
***Cadence / Torque Sensor Inactive Profiles:**
***ECO Mode:** Limits peak battery current draw for maximum cruising range.
***CITY Mode:** Balanced power delivery optimized for stop-and-go urban traffic.
***SPORT Mode:** Unlocks maximum controller power and instant acceleration for steep hill climbs.
***Two-Stage Password Protected Setup Menu:**
* Access internal settings by pressing and holding **UP + POWER** from the main screen.
* Input factory default **PIN: 1234** to calibrate rim size (6 to 30 inches), Auto-Power-Off delay (3 to 15 minutes), speed limits, and battery OCV curves.

Section 4: Diagnostic Test Interface & Safety Safeguards
Real-Time Hardware Telemetry and On-Screen Fault Identification
Designed to function as an on-board diagnostic workbench, the LCD135C allows technicians to analyze hardware health without external diagnostic tools.
***Unloaded Startup Torque Sensor Calibration Protocol:** Executes an automatic zero-point calibration upon powering on torque-sensing DM01 or DM02 mid-drives.
***
Critical Requirement:** Pedals and crank arms **must remain completely free of weight or pressure** during power-on to prevent improper baseline torque recording.
***Comprehensive "eBike Test" Interface:** Mechanics can enter the test menu to view live telemetry across all connected hardware subsystems:
***Electrical Telemetry:** Bus Voltage (V), Bus Current (A), and Motor Phase Current (A).
***Motor Dynamics:** Motor RPM, Back-EMF Constant, and Transmission / Reduction Ratio (RR/TR).
***Sensor Voltages & Signals:** Live Throttle voltage (V), PAS Cadence (RPM), and Torque Sensor output voltage (V).
***Status & Thermal Monitoring:** Live Speed and Shift sensor states, Controller Temperature (°C), Motor Temperature (°C), and real-time Hall Sensor phase states.
***Clear Text Error Reporting:** The display replaces obscure error codes with clear, on-screen text descriptions for quick troubleshooting (including Communication Interrupted, Protocol Mismatch, Motor Blocked, Speed Sensor Fail, Motor Hall Fail, Controller MOSFET Fail, Controller OverTemp, and Motor OverTemp).
