my knee keeps hitting the handle bar?

Question

wahts should i do besides doing somethng withthe handle bar!

Answer 1

My first question: Are the wheels the right size for your age?

12" Wheel Cycles - Suitable for ages 2½ to 4

14" Wheel Cycles - Suitable for ages 3 to 5

16" Wheel Cycles - Suitable for ages 5 to 7

20" Wheel Cycles - Suitable for ages 7 to 9

24" Wheel Cycles - Suitable for ages 9 to 11

26"+ Wheel Cycles - Suitable for ages 11+ (These are classed as adult cycles.)
-----------------------------------------------------------------------------------

My second question: Do you have the right size frame for your height?

The following rules of thumb should be applied when you try a bike for size:

Racing Bikes: Standing flat footed on the ground, you should have a minimum of 1" clearance between yourself and the top tube of the frame

Mountain Bikes: Standing flat footed on the ground, you should have a minimum of 3" clearance between yourself and the top tube of the frame.
----------------------------------------------------------------------------------

My third question: is your seat adjusted correctly?

To adjust the seat height, wear your biking shoes and riding shorts and place your heels on the pedals.

As you pedal backwards, your knees should fully extend in the down position. If your hips rock side to side the seat is too high. Now when you move your foot into the proper pedaling position, with the balls of your feet over the pedal, you'll have a slight bend in your knees.
-------------------------------------------------------------------------

If you answer "No" to any of the questions, correct the problem and you should stop hitting your knees.

Answer 2

Try raising your saddle.

After that try improving your grammar, punctuation and capitalization

After that buy a bike that fits. I'm not being sarcastic. It used to be possible to adjust handlebar height easily but due to production cost the "Threadless" headset has replaced the older threaded sets. The marketing hype was that they were "New and improved" though the real reason was that the entire process could automated and the guy in the factory who got paid $1.00 a day to adjust headsets was fired

Look around online you can find several sites that tell you how to fit your bike

Answer 3

Try raising the seat. It would allow your knees to rise less. In real terms, you have to raise the handlebars too, as raising your seat only, would make you hunch more.

I think de bike may be too small for you if your bike is smaller than a 26" wheeled bike. If it is 26", than the seat and handlebars ought to be raised. try it, if you can't do it yourself, get someone else to do it. Most bikes come equipped with quick snaps so you do not need a spanner or monkey wrench.

Answer 4

Raise your seat, for one thing. Your leg should be nearly straight at the bottom of your pedal stroke.

But it sounds like your frame is too small to begin with.
