I've been making my own tire changing equipment for my motorcycles for many years; experiment after experiment. By the looks of it, the problem with your first breaker bar is that the plate that contacts the tire is not wide enough. When it's so narrow, not enough of the bead dislodges from the rim and then just springs back. It also needs a longer rear down below the top of the rim. That same springing back action happens with this too. I love seeing how other people tackle changing their own tires. Good on ya.

That is beautiful I love it!

😂 Te sale mas facil hacer palanca en lugar de bombear con el pie.
