The Big Dog’s motor uses an updated 750W Upgraded Brushless Geared Hub Motor and specialized inner ring, which enables high-temperature resistance and better heat dissipation. This inner ring reduces the motor magnets’ attenuation speed, which guarantees longer life expectancy for the motor, meaning your Himiway Big Dog will outlast the competition where it matters most—the power system. Big Dog’s brushless geared hub motor will help you conquer any obstacle in your chosen terrain.
