I have almost that same unicycle (switch out the pedals and the KH seat for a miyata airseat) and I weigh close to 200 pounds as well. You wont break/bend the frame unless you’re trying some weird frame grinds or something. Also, correct me if I’m wrong, but aren’t Bedford, Yuni and Nimbus II frames basically identical?
The peace of mind that comes from having the profiles is worth it enough for me.
