Ribbed Urethane 70mm Wheels (DRV Kit & More)

Grippy and squishy general-purpose wheels, perfectly sized for any 2WD SCARAB build or our DRV kit!

At 70mm diameter and pocketed to fit our awesome, lightweight flange hubs for 4mm, 5mm, and 6mm shaft-drive motors. These wheels are made to pair with our SCARAB hubmotor drum system, being about 5mm larger in diameter than the drum. However, they are pretty versatile for plenty of other builds and projects. Featuring injection-molded Nylon 6 hubs and cast 50A urethane flexible ribbed tires, these are meant to take a serious beating and keep on rolling. Design and color may change in future batches.

Black wheels are ~105 grams (0.231 lbs) per pair, red are ~93 grams (0.205 lbs) per pair. 

• BLACK wheels - first ever batch. Slightly thicker ribs. Reworked on CNC in-house, so there are some fuzzy nylon burrs. These don't affect functionality. 
• RED wheels - second batch, but still needed rework but came out cleaner.
• Future batches - most likely will be black treads, details TBD as of July 2026
