Hi everyone, this is my first post so bear with me. Here is my situation. I am new to biking. Two years ago I decided I wanted a bike so I went to Dick's Sporting Goods and bought the cheapest Mountain Bike they had. A Quest Rialto for $149.99. Two years later I realize I am more interested in cycling and am wondering if I should upgrade. I would like a bike for fitness purposes and to take bike rides with my family so after lurking around your forum and doing research, I figure a hybrid bike would be the best match. I would be using the bike on roads and cement bike paths so I don't use the mountain bike for what its intended. I am looking at the $400-$500 range. My question is, would I notice a big difference in the following areas if I were to upgrade to something like a Trek 7.1 or 7.2FX, a Specialized Sirrus, or Cannondale Quick 6 or 5 vs. the bike I have? Would it be worth it to upgrade? I just wanted to get some advice before I took the plunge.
Thanks in advance for your help.
