The Wicked Smart Bearing Remover By Villy is a pretty nifty product. It takes a second to get your head around but is super easy to use and very helpful in popping bearings out.  This is very useful for popping bearings out of ALUMINIUM CORE wheels. Certain to increase the longevity of the wheels. 

Top tip: Push the smaller part to the side to latch to the underside of the bearing. Then use a flat surface to push up from the other side. Watch the video below for more context.
