If you're only 16, then it's a good start to establish good habits before your bad habits take over as you get older and life gets in the way of sensible eating and exercise.
Cut out the fast food and sugar intake - and beer too.
Keep up with the bike riding being a part of your day instead of viewing it as specifically for exercise. That is, reduce your dependancy on your car ( if you have one).
