Anyone know where I can buy a decent cheap bike?  I stopped by Century Cycles in Rocky River today, which has very cool bikes, but I don't plan to be a serious cyclist and everything there was quite expensive, I'd just like something servicable for pleasure riding during the nice weather.  (And of course to be able to explore my surrounding neighborhoods more extensively than I can on foot.  :-D )

The Ohio City Bike Co-Op offers used bikes you can purchase, I believe. Or you could get a beater at a thrift store and then take it to the co-op and get them to teach you how to fix it.

I echo the Ohio City Bike Co-op. They have a good website --  http://www.ohiocitycycles.org/ -- where you can find out when their social rides are, or if you want to get your hands dirty and make new friends they have fix-a-thon nights there, as well as classes on how to fix bikes. Terrific stuff.
