i had a short stint on an Ozonys Cannibal with a 45~ bb rise.
I found it harder to land most moves, gaps were about the same distance, but when I landed I woud just fall off the back of the bike, same with taps and hooks. The main issue for me was sidehops, it completely ruined me! I was previously at around 48", but once I got on the Ozonys they went down to about 42". I kept on hitting the wheel against the side of the rock/wall instead of landing on top. It felt like I had to jump higher than I would on a lower bb bike.
