At the end of my bike ride last night with my Son I pulled off a perfect tiny bunny hop for him. LOL. Not sure how high I was but it felt good. I wasn't sure I was going to get any air cuz I was on my cruiser.
I'm thinking about getting some bmx handlebars and the right kind of stem for my sons bike. I ride it sometimes. The bars are just a hair too low on it for me. I think it would make it feel better and I have gotten air with that bike before too. I got that bike for 15 bucks from a kid selling it on FB Marketplace and I think it's a decent bike. I'ts a mid 90's Schwinn Hurricane and I hear the quality was good on them back then.
Definitely not a BMX bike but.... could make a hybrid from it though. I still want to try a 20"er just to see if I would like it.
