There are plenty of Bikes around so to settle on one model early on is Not right. Get out to a few more shops and try a few more bikes. Make an allowance for the "Extra's" aswell. Cycling clothing- Helmet- Pump- basic tools and a new set of legs for when you do too much too early. Also- that group you want to join- Contact them now. They will be able to put you onto the shop (S) that will help you and give you a good deal.
