I'm trying to learn how to bunnyhop to get over certain obstacles in a park close to where I live. I ride with my saddle high up so either leg is fully extended on down stroke to prevent knee injury as I've been told but the bunnyhop tutorial video I've seen tells to keep the saddle low. Can I get away with keeping it up without crushed balls upon landing or do I stop a few feet from the log to lower the saddle?
