Riding your bike rids you of calories and fat. It is good to have a little bit of calories and fat, so you have energy, but to much can make you obese, and have a higher risk of diabetes.
When you ride your bike, or move in any way, you lose some energy, and most energy comes from the food you eat and the calories in them, that's why when you eat sugar you're more awake. If you ride your bike a lot, then you get tired because you lose calories, and once most of the calories are gone, you start burning fat, so the farther your house is, the more calories and fat you lose when
riding your bike.
A lot of kids are crazy when they get to school, but not when they just rode pretty far on a bike.
Riding your bike to school is not just a benefit for you, but your teacher too, she/he will have one less crazy person to worry about. When you are tired you are more likely to sit still and listen, and that will calm your teacher, and it is better for your academic grades, (you don't want to be crazy during a test). When you move a lot you soon get tired, so in this case it is better to not ride your bike to far or you will fall asleep in class, and not to short of a distance either or you wont lose enough energy, but about 1/4 of a mile to 1 mile is about enough for that day.
If you ride your bike alone or with 1 or 2 friends, it is not only good for your body but your mind too.
You can bond more with your friends and family and learn more about them, and if you are alone,
you can think and organize your mind, (if there is a special event coming up, how to fix some sort of problem, etc). After your bike ride you may be calmer, or have solved a hard problem, or know more about your friend or sister, but you will most' likely know something more about your self.
