I recently did a little bit of work to the Huffy beach cruiser that I picked up on CL for $30 last year. Other than some wheel truing, greasing the bearings, a new chain and some elbow grease it was ready to ride. I live close to Lake Michigan and use the bike and recently built trailer to carry my paddle board to the beach.

I'm working somewhere that has a powder coating line, so I talked them into doing the bike for me, not bad for $25

Before pictures with the trailer are from last summer, it's still cold here, so I haven't been able to ride the paddle board yet this year.
