These super-light wheels are made to fit perfectly on the Sanyo NA-Series gearmotors, or Copal 30/60 gearmotors, with just a simple press-fit on the output shaft. They fit perfectly in the Inertia Labs Ultralight Ant Chassis, and are protected by the chassis' built-in wheel guards.

These wheels are sold in sets of 4, and are available in smooth or treaded design. All are very grippy on most surfaces.

Please note that your rim style may vary from the photos here.
