20A Brushless Controller with TF-100 Display – The Ultimate Upgrade for E-Scooters and E-Bikes
Is your scooter feeling sluggish, is the display unresponsive, or are you simply looking for a performance boost? A high-quality brushless controller is the difference between a frustrating ride and a smooth, powerful experience. This 20A kit is compatible with 24V, 36V, and 48V systems and motors ranging from 350W to 1000W, making it a versatile solution for almost any standard setup on the market.
Note: The package includes the controller and the TF-100 LCD display. Please verify your connector compatibility with your specific scooter model before purchase.
Why choose this model? (Key Advantages):
- 24V / 36V / 48V Compatibility — Works seamlessly with the most common battery voltages without requiring modifications.
- 350W–1000W Power Range — A direct replacement for the original controller on most urban electric scooters and e-bikes.
- Automatic Self-Learning — Automatically detects and corrects motor rotation direction, eliminating the risk of damaging components due to incorrect wiring.
- TF-100 LCD Display Included — Features a P-Settings menu with 16+ configurable parameters, from current limits to cruise control, all managed via a clear, intuitive screen.
- E-ABS & Low-Level Braking — Provides gradual electronic braking to reduce brake pad wear and improve control in heavy traffic.
- Native PAS Support — Fully compatible with pedal-assist systems, making it ideal for e-bikes equipped with cadence sensors.
- Integrated Electric Lock — Includes an electric door lock function for an extra layer of security against unauthorised use.
Performance and Technical Details
The brushless BLDC architecture with Hall sensor support (6-wire) ensures smooth motor control at any speed—no jerking during start-up and no overheating at cruising speeds. The current limit is adjustable via P14 (1–20A), allowing you to fine-tune acceleration based on rider weight or terrain. The low-voltage protection (P15) prevents over-discharging your battery, effectively extending the lifespan of your battery pack.

To install the controller, follow these steps:
- Connect the phase wires by matching the colours between the controller and the motor.
- Connect the battery: Red = (+), Black = (–).
- Connect the throttle and the electric lock.
- Connect the Hall wires if your motor is equipped with Hall sensors.
- Connect the self-learning wires to detect the rotation direction:
- If the wheel rotates in the correct direction → disconnect the self-learning wires.
- If the wheel rotates in reverse → keep the wires connected until the direction automatically reverses.
- Connect optional features (headlight, horn, brake, PAS) as required.

Frequently Asked Questions
Is this compatible with my 500W / 36V motor?
Yes. The controller supports brushless motors between 350W and 1000W at 24V, 36V, and 48V. Please ensure the physical connectors match your specific model before installation.
What if I connect the phase wires incorrectly?
The self-learning function automatically detects the correct rotation. If the motor runs in reverse, simply follow the self-learning procedure described above—there is no risk of damaging the components.
Is the TF-100 display included or sold separately?
It is included in the package. You will receive both the controller and the TF-100 LCD display, ready for installation.
Can I use this on an e-bike, not just a scooter?
Yes. It works on any e-bike equipped with a compatible BLDC brushless motor. The native PAS support makes it perfectly suited for bikes with cadence sensors.
How do I set my battery voltage in the TF-100?
Enter the P-Settings menu (hold Power + Mode for 2–3 seconds) and adjust parameter P03 to match your battery voltage: 36V, 48V, or 52V.
