The best bicycle for fitness is the one that you get on and ride.
Fitness is a habit. Getting out there and turning pedals makes a difference.
My wife has a bike covered with dust and she complains about her weight
I have a mountain bike covered with mud and a tri bike with the saddle worn out and a cracked headset (being replaced) and most people look at my slim figure and comment positively.
So the best bike for fitness is the one that you are riding. The rest is all irrelevant details. Just get something and start riding it.
Hi. I quite agree with you that calorie intake is very important for losing weight, but you can't do without exercise. Keeping fit requires proper exercise. One of the most common home exercise machines is an exercise cycle that allows people to do exercises at home with ease. Going to revexpo.com I found 10 Best Exercise Cycles for myself and I am always in great shape.
