Mallet + extension bar has always worked for me, just make sure you hit them on the outer edges and not the inners so you don’t break the bearings. if you have a bike shop nearby they can do it more “professionally” with tool that removes them.

Need a good drift and hammer, and as storage as it steels, hitting hit with as much force as you can!
That’s it, there’s no magic trick to it

I had a bike that the bb just would not come out with a hammer and punch. Im a mechanical engineer for a living and do this shit daily. I had to break the inner race and run a bead of MIG weld on the inside of the outer race to get it out. Poor tolerances on the bb boss will be the cause. I made sure to use liberal amounts of anti size when installing the new bb bearings.

I use a 1/4” socket extension and hammer. Use the bigger end against the bearing and hammer from the inside out and try to evenly tap it out so it comes out straight.
