If cycling, or any type of physical activity like running, is new to you than I would buy a cheap no name bike, why you scream? Because about 93% of the people that start a new physical fitness program including buying gym memberships or buying a home gym, or shoes to run, or in your case a bike to cycle usually quite the activity in 3 to 6 months because they find out it takes time and energy and they would rather play video games or watch TV, so again in your case the recently purchased $1,200 plus bike becomes garage art. So I always recommend people that I know to buy a $350 or less bike to start on, and if at the end of 3 years they're still riding and riding almost everyday and now want a bike to match their abilities and want a reliable bike for long distance rides then buy a better bike and save the old one for camping or commuting. Obviously after reading this if for example you run now and been running almost everyday for years then going to cycling won't be a big deal and if you want to spend more then I would stay away from generic low cost bikes because the more miles you ride from home the more reliable you need your bike to be. I hope that made sense.
If you decide to spend less than $350 I would probably start by looking at used bikes rather than new bikes because new bikes in that price range are junk, sorry to say. So go to Craigslist and start looking, if you see something you may want to consider buying post here and let us tell you if it's a good deal. Of course make sure any used bike you're considering fits.
