Riding my bike...the benifits?

[Indie]

ok so ive decided to ride my bike for 40min approx, 4+ days a week to slim down all over. the main areas i want to disappear is thighs,bottom and chest area...will cycling do this for me?? and i do not wish to bulk up in leg muscle, can i prevent this?? finally how long must i do this before seeing results...all appropriate and informative answers will be much appreciated.

I cycle around 5 days a week, around 2 hours per day, but to be honest, I haven't noticed my chest area get slimmer (neither my stomach - i wish) but have noticed the muscles in my leg to get a bit bigger.

cycling is cool anyway! At least you get out and about rather than all those lazy buggers in their cars - also its quite funny when you see them waiting in massive traffic jams, and you're just cycling past.
