Perhaps...as a long time bike rider of many different disciplines, one unfortunate aspect is that it's not very good exercise, anything that you do has to be regular and of sufficient intensity. Thinking of it as a way be active on the other hand can work out decent. There are many good brands and bikes out there, nearly anything from one of the "major" brands (Trek, Specialized, Giant, Kona, Novaro(REI), etc, will be of equal quality and capability. Beware anything sold in Walmart or similar department stores, as the quality is just total crap, they will go out of adjustment quickly, bearings will seize, soft metal parts will bend/break, etc. Go to a few bike stores and see if they have any beach cruiser models, that will ultimately be the limiting factor, as it's not likely that all of them will even carry a beach cruiser model, but it's also likely that at least some of them will. You want to ride it and see how it will work first, regardless of any recommendations towards a particular model. Sizing is super-important, you want to be sized correctly, again, stuff that points towards trying them at the shop. They also make bikes now that can be ridden on (relatively firm) sand, with much bigger tires than beach cruisers, although they are much more expensive too.
