Here is my dilema: I am getting a bike for exercise to ride primarily on paved bike trails here in Michigan. I'm 45 and a tad overweight. I'm fairly certain I want a hybrid. I have found a year old Giant Cypress thast includes a lock, water bottle and computer for milage and speed. Previous middle aged guy bought it and decided biking wasn't for him. He claims it has 60 miles on it. I can buy this bike for around $300. Second choice is to buy new from my LBS. I know the shop well and have bought my kids bikes from there for years. He recommended me to a Diamondback hybrid (the one with the funny new handlebars.) He recommended I get an upgraded seat and different bars. His price is around $350 without the extras that come with the Giant. I like supporting this LBS, but am leaning toward the Giant. (better value in my mind) LBS is not a Giant dealer (local Giant dealer is a chain of stores.) Is one bike better than the other of these two? How important is the dealer in a purchase decision? Can I take a Giant to a Diamondback dealer for maintenance or is that considered in poor taste if I didn't buy it there? Thank you and love this "beginners forum!"
