Can't comment on the model but KHS do make some fine bikes. Only way to find out what bike is for you is to get to a shop and test ride the ones you are interested in. And can assure you that retro has it right on outdoor storage. You may have a "Rustfree" frame but anything steel- like brake springs- cables and nuts and bolt will detiorate very quickly. Rusted gear cables do not shift cleanly.
