A gearless hub motor wheel refers to a type of electric motor used in electric vehicles (like e-bikes or electric scooters and so on) where the motor is integrated directly into the wheel hub. It doesn’t use gears or a transmission system to transmit power from the motor to the wheel, hence the term “gearless.”

A geared hub motor wheel is another type of electric motor system used in electric wheelbarrow, electric cart, and other electric vehicles. Unlike a gearless hub motor, a geared hub motor incorporates a gear mechanism inside the motor casing, which helps to amplify torque and improve the motor’s performance, particularly at low speeds or under heavy loads.

Mono shaft and double shaft both can be provided
From 4inch to 16inch, all can add the encoder inside the motor if you need it for robotics
