Congrats, good choice imo! It is a nicely balanced, fairly smooth and quick bike for a hybrid. I have a Quick 3 that I love. I tried many, many hybrids, and the Quick was the best for me. In fact, I'm looking to get a CF road bike now, and my Quick 3 is my comparison. Most aluminum frame road bikes have not been any faster than my Quick. I feel at one, very balanced and glidey.

Whether to go up a model depends on what you're looking for in your bike. If you want something with wider tires for dirt and gravel the 5 is fine. I wanted something we could set up more as a flat bar road bike, and with the narrower tires the 3 was perfect. I have it set up in a more aggressive, less upright position, with more stretch. The Quicks can be quite upright too, if that's what you prefer. The narrower tires of the 3 are faster tyhan the 4 or 5on pavement. The lower models will be slower. If the 4 or 3 are what you want, it's cheaper now to get it than to want to upgrade in a couple of months (ask me how I know THIS one!). So try to ride them, and see the difference. Get EXACTLY what you want before you pull the trigger!

The saddles are not terrific on the Quicks, unless it's positioned exactly right. I just upgraded. It's an easy switch. My experience has been that my shops DO sell that particular bike on the floor. They don't sit long this time of the year, often they've just been put together and brought out to the floor. If for any reason you're not happy ask them to assemble a new one, once/if you decide to go with the 5. I wouldn't accept a noise in the wheel. But it may be an easy fix.
