20A Brushless Controller with TF-100 Display – Complete Upgrade for Your Electric Scooter or Bike
Is your scooter stuttering, is the old display unresponsive, or are you simply after more power? A quality brushless controller makes all the difference between a frustrating ride and a smooth, effortless cruise. This 20A kit supports both 24V and 36V setups, handling motors anywhere from 350W up to 1000W—covering practically any standard configuration on the market.
Note: The package includes both the controller and the TF-100 LCD display. Please check connector compatibility with your specific scooter model prior to purchase.
Why Choose This Model? (Key Advantages):
- 24V / 36V Compatibility — works seamlessly with the most common battery setups straight out of the box without any extra modifications
- 350W–1000W Power Range — acts as a direct drop-in replacement for the original controller on nearly any urban electric scooter or e-bike
- Automatic Self-Learning — automatically detects and corrects the motor’s direction of rotation, removing the risk of shorting components due to miswired connections
- TF-100 LCD Display Included — features a P-Settings menu with over 16 customisable parameters, ranging from current limits to cruise control, all managed from a single crisp screen
- E-ABS Brake + Low Level Brake — provides gradual electronic braking that reduces brake pad wear and improves handling in busy traffic
- Native PAS Support — fully compatible with pedal assist systems, making it ideal for cadence sensor-equipped e-bikes
- Integrated Electric Door Lock — built-in ignition lock function for an extra layer of security against accidental startups
Details and Performance
The BLDC brushless architecture with Hall sensor support (6-wire) guarantees buttery-smooth motor control across all RPM ranges—no jerky starts off the line and no overheating at cruising speeds. The adjustable current limit via P14 (1–20A) lets you tailor the throttle response to suit the rider’s weight or terrain type. Meanwhile, the low-voltage protection (P15) prevents over-discharging your battery pack, which translates directly to a longer lifespan for your battery.

To wire up the controller correctly, follow these steps:
- Connect the phase wires matching the colour-coding (matching the exact colours between the controller and the motor)
- Connect the battery: red = positive (+), black = negative (–)
- Connect the throttle and the electric lock
- Connect the Hall wires if your motor is equipped with Hall sensors
- Join the self-learning wires together to automatically detect the correct rotation direction:
- If the wheel spins in the correct direction → unplug the self-learning wires
- If the wheel spins backwards → keep the wires connected until the direction automatically reverses
- Connect optional features (headlight, horn, brakes, PAS) as needed

Frequently Asked Questions
Will this work with my 500W / 36V motor?
Yes. The controller supports brushless motors ranging from 350W to 1000W at 24V and 36V. Make sure to double-check the physical connector compatibility with your setup before installation.
What happens if I wire the phase cables incorrectly?
The built-in self-learning function automatically detects the proper spin direction. If the motor runs in reverse, just follow the self-learning procedure outlined above—there is no risk of damaging the components.
Does the TF-100 display come included or do I need to buy it separately?
It’s included in the box. You’ll receive both the controller and the TF-100 LCD display together, ready for installation.
Can I install this on an electric bike as well as a scooter?
Yes. It works on any e-bike equipped with a compatible BLDC brushless motor within the specified power range. Native PAS support also makes it a great fit for cadence sensor-driven bikes.
How do I set my battery voltage on the TF-100?
Enter the P-Settings menu (press and hold Power + Mode for 2–3 seconds) and adjust parameter P03 to match your battery’s rating: 24V or 36V.
