Electric bike controller – ref. 243‑T26FC‑01V / D3F4EA01176
General description
The 243‑T26FC‑01V (D3F4EA01176) controller is the electronic heart of an electric bike (e-bike). It manages the flow of power and signals from the battery, sensors (pedal, brake, speed), throttle, and display, transmitting commands to the motor to provide pedal assistance. In other words, it’s the “brain” that synchronizes pedaling, battery, motor, and rider.
This controller ensures that electric assistance is smooth, safe, and perfectly adapted for urban, trekking, commuting, or mountain biking use.
Key features & specifications (typical / generic)
| Feature / Function | Description / Typical Value |
|---|---|
| Motor Compatibility | Brushless (BLDC) hub or mid-drive motor, with pedal-assist (PAS) or torque sensor |
| Sensor Management | Reads signals from pedal sensor, speed sensor, brakes, throttle, and display |
| Assistance & Safety | Adjusts motor power based on user input; includes protections against overcurrent, overvoltage, low battery, overheating, and motor cut-off during braking |
| Installation / Integration | Interfaces with wiring harness and connectors; compatible with most standard motor/battery kits |
| Thermal Management | Passive heat dissipation housing prevents overheating during long rides or climbs |
| Riding Smoothness | Provides fluid pedal assistance, gradual start, and instant motor cut-off for safe, responsive riding |
Purpose on an E-Bike
-
Analyzes rider input: The controller detects when you pedal via the PAS or torque sensor and adjusts motor power for smooth, natural assistance.
-
Manages battery energy: Monitors voltage and current, protects battery and motor, and cuts off motor power during braking or overheating.
-
Ensures safety and compliance: Stops assistance above legal e-bike speeds (typically 25 km/h in Europe) and meets legal pedal-assist requirements.
-
Supports compatibility and modularity: Works with various motors and batteries; suitable for replacement or upgrade.
Giant E-Bike specifics
For Giant e-bikes, this controller integrates perfectly with the brand’s electronic ecosystem, including RideControl or RideDash displays. These systems allow you to manage pedal assistance, monitor battery range, speed, and distance, delivering a smooth and ergonomic riding experience.
Giant ensures that its electronic components (motor, battery, wiring, controls) are covered by warranty when installed according to manufacturer conditions.
Ideal users / use cases
This controller is ideal for:
-
Urban e-bikes, commuter bikes, trekking e-bikes, or hybrid e-bikes seeking reliable and comfortable assistance
-
Users needing a simple, stable, and durable solution to replace a faulty controller
-
DIY enthusiasts or e-bike technicians restoring or upgrading an electric bike
-
Riders who want smooth assistance, gradual start, responsive braking cut-off, and electrical protections
Usage tips & checks
-
Check motor and battery compatibility before installation (BLDC type, voltage, connectors).
-
Ensure all wiring is intact to prevent short circuits or poor connections.
-
Verify that the controller supports any modifications (display, battery, motor) — some models are more “universal,” others more “dedicated.”
-
Keep the controller housing dry and protected from water or mud to preserve electronics.
-
For legal pedal-assist operation (up to 25 km/h in Europe), avoid reprogramming the controller to exceed speed limits — this may make your bike illegal for public roads.
