Okay the cheater wasn't THAT bad Which confirms that This backstory wasn't used to excuse the character but just to showcase more of his personality and way of thinking.
Before someone replies "who asked", nobody did but I saw another comment that this chapter still doesn't excuse anything so I wanted to explain that the purpose is to see more of the character not to excuse him.

He was going to die if he refused to get in the right riding position ( no metaphor ). Bike riding partners also need to study a bit when going on good bikes. As a victim of a bike ride fall when I was 10 it's not a good experience even if u are basically left unharmed. This kinda thing scares the shit out of the rider
Everybody is fine as hell, like be my daddy as well damn
