I am a regular mountain biker, but like to road-ride, too. However, my full-suspension is way too much drama for the pavement and even my hardtail is too heavy for efficient road travel. I want something lighter and better suited. The problem is, I am not super fond of the "feel" of road bikes. I saw that Trek (my fave) had "fitness" bikes and "urban" bikes and I am wondering if anyone can tell me what are the advantages/disadvantages to choosing a fitness or urban bike over a road bike?

THANKS!
Just to add, a fitness bike is not a stationary bike. It is an actual style of bicycle like urban, road, mountain, triathalon, etc. I was just hoping that someone had some info on what might be better suited for me. Thanks to anyone who can help!

I’m absolutely loving my new swimming lessons at the YMCA. I want to take the Water Fitness Challenge & Water Fitness Workout classes instead of the cardio workout I had been doing; walking on a treadmill, stationary bike etc

Is this a good idea? I have been pretty sedentary since last summer… Can I achieve the same results with all water fitness?
