The sin guy and I are looking for cruiser bikes to ride on the beach and the flats. We have very nice 21 speeds in storage, heh, and just want something simple and inexpensive to ride on the beach and be left out exposed to the elements (salt, sand, sea, rain, snow). Any recommendations? I have been reading craigslist like crazy and all of the good ones seem to go in 30 minutes or less. What's left are Walmart specials for $10-20 less than new.
