Just starting to get into the sport. Not interested in hardcore training or racing, just looking for something both zippy and comfortable. I'd love a bike that I can push myself in for a couple hours, then do some sightseeing and exploring at a more relaxed pace, before riding home again, if you get the picture. I don't have a hard dollar limit, but I'd strongly like to keep it under $1000, and hopefully a good deal less than that. I'd really love some recs of bikes to try, preferably models that offer excellent value that more experienced riders have been impressed with.
