Add to wish list

The 1090-POLOLU is a pair of custom designed white plastic wheel frame inside the rubber tire.

These wheels are sold in pairs.

This rugged wheel is designed to fit securely on output shafts of micro and 15.5D metal gear motors.


  • Diameter: 1.65" (42 mm)
  • Width of tire: 0.75" (19 mm)

Note: The output shafts on the Solarbotics metal gear motors will also fit these wheels, but because they are shorter they will have to be mounted onto the other side of the wheel where the fit is tighter (which means the Solarbotics metal gearmotors will not work with the quadrature encoder associated with this wheel). Therefore, the teeth on the hub optionally allow a reflectance sensor to be used for encoder feedback.

Note: The encoder, gear motor bracket extender, and the micro metal gear motor are sold separately.
