OK so a little history on this bike I have to go look at tomorrow, This older gentleman contacted me a couple weeks ago about this old Hiawatha cruiser he rides (Hes only form of transportation) when I picked it up it was just a mess, the front wheel bearings was pretty gone completely and the rim was bent, one pedal was cross threaded but in there tight, the rear cog was popped off with the clip ring just hanging around the axle. oh and a front fender of mystery origin just crammed in the fork held on by the strut. Well I fixed or replaced everything and test rode it and it was riding nicely so I took it back to the guy. Well he called me tonight and told me it rode fine for about a week then it started slipping when he would be pedaling and it just kept getting worse. So Im thinking somethings not catching in the rear hub. Guess I'll find out tomorrow whats wrong with it. Not sure who rigged it in the first place but it has become one heck of a headache for me.
