Universal E-Bike Controller 36V-72V 500W-800W Sine Wave - Brushless Motor Controller With Self-Learning

DIY e-bike builders and repair folks, this universal brushless controller is your ticket to getting almost any electric bike or scooter back on the road! It handles a wide voltage range from 36V all the way up to 72V, with power output from 500W to 800W depending on your setup. The sine wave technology means smoother acceleration and quieter operation compared to square wave controllers. The self-learning feature is brilliant - just connect two wires and the controller automatically figures out your motor's phase sequence, no complicated programming needed. You get all the features you'd expect: 3-speed settings, pedal assist (PAS), cruise control, reverse function, and both high and low brake cutoff options. It works with both 60 and 120 degree phase angle motors, and the wiring includes connections for throttle, hall sensors, LCD displays, and pretty much every accessory you might want. Whether you're building a custom e-bike from scratch or replacing a fried controller on an existing ride, this versatile unit has you covered. Just make sure to match your battery voltage and motor specs, and you'll be riding smooth in no time!
