Fitness What Is The Difference Between A Fitness And Bike And A Road Bike?

What is the difference between a fitness and bike and a road bike? - fitness

I am a regular mountain biker, but as a road trip, too. However, I am a full suspension is a tragedy for the sidewalk, and my stiff too heavy for the trip. I would like to respond a little easier and better. The problem is that I am not super friend "feel" for road bikes. I looked at Trek (was) my favorite "bike-fitness" and "urban" bike and I'm wondering if someone can tell me what are the advantages and disadvantages of choosing a gym or d 'a city bicycle on a road bike?

THANK YOU! :)
