A pair of rubber-tyred ABS wheels designed to fit N20 mini metal gearmotors and compatible Solarbotics metal gear motors. The hub features teeth that can be used with a reflectance sensor for encoder feedback, adding speed and position sensing to your robot.
The wheels press-fit onto the gearmotor output shaft — initially sliding in easily, then achieving a snug fit at the far edge of the hub. For Solarbotics motors with shorter shafts, mount from the opposite side where the fit is tighter.
Key Features
- Rubber Tyre – Good grip on smooth surfaces
- Encoder-Ready Hub – Built-in teeth for reflectance sensor feedback
- Press-Fit Mounting – Fits N20 and compatible gearmotor output shafts
Specifications
- Diameter: 43 mm
- Width: 9 mm
- Weight: 14 g (per pair)

Jargon buster
Plain-language definitions for the technical terms used above.
- encoder
- An encoder is a sensor that converts the rotation or position of a shaft, knob or dial into electrical signals, reporting movement as incremental steps and direction, or as an absolute position. It is used to track how far something has turned, which matters for precise positioning, speed control, repeatable movement, or using a rotary knob as an input.
