How to ride a bicycle im 12?

hey there i need help on how to ride a bicycle im 13 and i tried to learn how to ride a bicycle when i was 7 but i clearly coudnt do it. The thing i cant do is balance on the bike, i can pretty much pedal but i just need to learn how to stay balanced on the bike. I dont care if i get hurt i can bear the pain.

I just got some bike from walmart on sunday

Take the pedals off your bike (you may need a special tool and the left pedal has a reverse thread. A bike shop should do this for you VERY cheaply). Lower the seat so that your feet can reach the ground. Push off with your feet and coast as far as you can. When you get accustomed to that, push off and when the bike slows down, push off again. Then go for 3. After 3, put the pedals back on. Push off with your feet and then use the pedals to keep going. As you get more confident, raise the seat to a normal position and use the pedals to start off.

HTH

ahh ok... well do it till you get it right

Cool. if you can bear the pain then.. there really is going to be no problem with biking. All you have to do is keep force into your hands but not too much and just keep them straight..
the angle of what your arms or hands are like is most likely to be part of the angle your bike wheel has turned. The best way i can explain this is by telling you to use your brain and control your front wheel. Its not really that hard. Most people cant bike cuz they are scared XP

just keep on practice, tell your mom to hold the sit for you to balance you while you riding it and when you think you can do it
just tell her to let go and jeep trying
