Description

This Universal Parts 9x3.5-4 rear wheel assembly helps get your compatible stand-up scooter rolling again without piecing together a rim, tire, bearings and sprocket. The mounted tube-type tire features a street/turf block tread, while the included 55-tooth sprocket matches a #25H chain drive. With a silver-finished rim and pre-installed bearings, it's a practical replacement for a worn or damaged rear wheel.

  • 9x3.5-4 tube-type tire: Street/turf tread with closely spaced blocks.
