I am a casual rider who has been riding for over 30 years and I need some good advice which is why I came here. I have only had two bikes my whole life one was a Kabuki which I bought in 1979, and then a friend had given me a Fuji from about the same era when the Kabuki fell apart a couple years ago . I ride basically for 5 months of the year and roughly around 50 miles a week at most . Well today my Fuji's frame cracked and I am without a bike and I feel lost. I need to get a replacement but at 52 years old I am pondering which direction I should go plus I really didn't want to break the bank. Do I go the Walmart cheapo route(Schwinn) ,go a little higher thru Amazon( Dawes),or go the used route or spend even more and go for some better brand. Any help would be much appreciated good or bad.Thanks.
