1800w/2.5hp 48V 32A ELECTRIC MOTOR KIT UNIVERSAL BUGGY BIKE QUAD MOTO DIY

This 48 V brushless DC drive kit pairs a high-speed MY1020 motor with a matched two-mode controller limited to 32 A for use in lightweight EV applications such as buggies, bikes, quads and small moto projects. The motor delivers 1800 W (2.5 hp) and the controller supports multiple control functions including three-speed selection, cruise, reverse, PAS and both low- and high-level brake inputs, with comprehensive wiring brought out to clearly identified leads.

NO INSTRUCTIONS INCLUDED
