I bought 2 bikes from a CR member a few years ago for a good deal.
21 speed aluminum frame with front/rear shocks. will need a complete tune-up. I took this to the alum creek trails a few times and it would be great with a little love.

2nd bike is a basic smaller mountain bike that is yellow. probably good for a 10 year old or someone around that age. no pic.
PM me if you are interested in taking both.
Both are FREE OBO.
