48V 60A E-Bike Controller
Description
eBike Controller 48V–72V 60A – Sine Wave with Self-Learning for High-Power Brushless Motors
Intelligent sine wave controller with 18 MOSFETs, 60A maximum current and multi-voltage compatibility: 48V/52V/60V/72V. Designed for 2000W–3000W brushless gearless motors, it delivers smooth, quiet and efficient power transfer with full protection and automatic phase self-learning.
Unlike standard square wave controllers, sine wave technology generates a pure sinusoidal signal to the motor, eliminating vibration, reducing noise and improving energy transfer efficiency. At 60A maximum current and 48V/52V/60V/72V compatibility, this controller is the central component for any extreme-performance build or upgrade of an existing conversion kit.

Sine Wave vs Square Wave — why it matters at 60A
At high currents (60A), the difference between sine wave and square wave becomes critical. A square wave controller generates a stepped signal to the motor, producing mechanical vibration, audible noise and additional heat losses. A sine wave controller generates a continuous sinusoidal signal, similar to mains supply, which means smoother start-up, noise below 60 dB, higher efficiency and less thermal stress on the motor windings at maximum load.
Phase self-learning function
Incorrect phase wire combinations between controller and motor are one of the most common installation errors. The self-learning function eliminates this problem: after a 30-second procedure with the wheel lifted off the ground, the controller automatically identifies the correct phase order and stores it permanently. No need to manually test all six possible combinations.
Integrated protections
The controller includes complete protection: overvoltage, undervoltage (cut-off at 40V), overcurrent, overload, overheating, motor lock and anti-runaway. The black anodised aluminium casing acts as a passive heatsink, dissipating heat from the MOSFETs without a fan and without moving parts.
Which Kits and Systems It's Recommended For
2000W MTX Kit
A direct replacement or upgrade for the 45A controller included in the 2000W MTX conversion kit. Delivers 15A extra headroom and sine wave instead of square wave.
3000W MTX Kit
The natural pairing for the 3000W MTX conversion kit — same 60A current rating, compatible with the 48V/60V/72V voltages supported by the kit.
Custom DIY Builds
Ideal for builders assembling an e-bike from scratch, combining a 2000W–3000W hub motor with a 52V or 72V battery.
Recommended Batteries for This Controller
At 60A maximum current, the battery must have a BMS rated for at least 45–60A continuous discharge. Our recommendations:
52V 20Ah Triangle Battery
The balanced option for 52V systems — weight centred in the frame, built-in LCD display. View the 52V 20Ah Triangle battery.
72V 20Ah Triangle Battery
The maximum voltage supported by the controller — maximum power, maximum torque. View the 72V 20Ah Triangle battery.
Installation and Wiring
Installation Steps
- Connect the motor phase wires (3 thick wires) to the XT150 outputs
- Connect the Hall sensor connectors (6-pin) from the motor
- Connect the battery via the XT90 connector — observe polarity
- Connect the display, throttle, PAS sensor and brake sensors
- Run the self-learning procedure with the wheel lifted before first use
Safety and Maintenance
- Do not cover the casing — passive thermal dissipation requires airflow
- Periodically check XT150 connector tightness under heavy load
- Never exceed the BMS discharge limit of the associated battery
- Operating temperature: −40°C to +80°C
