I use to ride for years when I was younger, and now after years of dedicated interest my 10 year old son is ready to ride. So I am now looking to purchase a bike for myself and am having trouble figuring out what size of bike will be more beneficial. We live in Oregon and am surrounded by riding opportunities galour. So thre bike size I'am contemplating is either a 200 or 230 or am I wasting my time and should just look into the 250's. Please let me know.
