Are you just bored out of your mind. Well if you are go for a bike ride with a friend.
There are some very fun places to go biking. You could go to a special place or just go biking in your neighborhood. My friend learned how to ride with no training wheels because when he was biking in his neighborhood they just fell off of his bike.
When you are biking you should always where a helmet anyways it’s the law to wear a helmet when you are riding a bike. If you are practicing with no training wheels for the first time in is good to wear knee and elbow guards. People usually learn to ride without training wheels when they are about 5 years old, but I did learn when I was 4 years old.
