1800w/2.5hp 48V 50A Electric Motor Kit Universal Buggy Bike Quad Moto Diy

This 48 V brushless DC drive set pairs a high-speed MY1020 motor with a compatible two-mode controller for e-bike and light EV applications. The motor outputs 1800 W at a rated 4300 r/min and is CE approved. The controller supports automatic motor phase identification, multiple brake signal types, three-speed modes, cruise control, reverse, PAS input, throttle interface and anti-theft integration. Further details and wiring guidance can be found in the instructions inside.

Features

• Brushless DC motor with hall sensors
