This is a rear wheel-hub assembly tested to function correctly 

**Fits Luba 2 LOW and HIGH **  

very cool wheel hub assembly for robotics project - simple encoders / wheel hub motors. 

There are two different style rear wheels for luba 2, one is clearly different (lug nuts on outside perimeter, and different lug pattern than the front)

Videos available of swapping unit, we can do it in about 20 minutes. Message for any questions thanks
