I have a Huffy Cranbrook that I have stripped the fenders and chainguard off and added 25 inch ape hangers to. This is my first cruiser that I have some what ratted and I'm excited! I have one problem with the bike, the seat post slips all the way down. Its so low that when I ride my calfs hit the back of my legs! Anybody have any suggestions? I'm a big guy 6'4 and 360 lbs.....Any suggestions would be greatly appreciated!
