How do you straighten a bicycle wheel? 20 inch kids bike.?

Answer 1

If it has spokes - there is a small tool you can buy that twists a small nut type flange at the outer wheel side of the spokes tighten on the ones that you want to pull with and loosen the opposite ones (close by not on opposite side of wheel entirely) accordingly - it's not hard - you'll figure it out.

just be patient and thorough and you can get it very straight even as a beginner.

Answer 2

even tho most of the answers are good ones a lot of repair shops still do it wrong. The first job is to get the stress out of the rim. most repair shops do this by tighning and loosining the spokes but that does not get the stress out of it. The first step is toget the hop out of the rim. this can be accomplished by loosining the spokes where it dips down and using a block of wood (2X4) and a hammer to pound down the indentation. 2nd use 2 plates of steel in a vice (should be 3"X8") putting the rim between the plates, then pull the wheel back and forth to remove the stress on the rim. then using a truing stand and spoke wrench the job is much easier.
I was at a bicycle shop one time and he had a badly bent rim he was going to throw away and I asked why he told me it couldnt be done he bet me 20$ i couln't do it. that was a 5 min. job for $20. it was a very useable wheel.

Answer 3

Uncleneal is correct. I am a professional mechanic, and I can true almost any wheel in a few moments, but only thanks to the tools that are available to me. There are trailside techniques that would use a piece of chalk to mark the high spots, but this is challenging, and you still have to know which spokes to tighten, and which to loosen. Once you have done that, then you need to check it for being round.
I would recommend taking it to your local bike shop. If you ask them to true the wheel for you and ask to watch the process, you might pick up a few pointers, but generally speaking, this is a job best left to the professionals.

I recommend you give the correct answer to Uncleneal

Answer 4

sometimes, if the wheels have those small spokes you can use a screw driver and some pliers to tighten the spokes. inside the wheel, after you take off the innertube, there is usually a piece of black rubber covering the ends of the spokes. remove that and the end of the spoles should look line a flat head screw. use the pliers on the nut looking thing on the spoke just under where the wheel and the spoke meet. and then use the screw to hold the spoke and tighten the spokes with the pliers. sometimes it works, sometimes it doesnt. depend on how bad the wheel is bent.

Answer 5

The tools you will need are called a "truing stand" and spoke wrench... and if you don't have one, take it to your local bike shop... otherwise, buy new wheels.

The process takes some practice so if you don't know what you are doing, better take it to a pro.

Answer 6

Memorize those formula or they are going to come decrease back and chew you in each math type you're taking!!! element of Parallelogram (A) is an identical because the bottom(b) situations the top(h): A=bh element of a trapezoid(A) is an identical as one-0.5 (a million/2)situations the sum of the bases(b?+ b?) situations top(h) A= a million/2(b?+ b?)*h Circumference(C) of a circle is an identical as "pi"(?) situations the diameter(d); C= ?*d section(A) of a circle is an identical as "pi" (?) situations the radius(r) squared: A = ? r² Perimeter(P) of a rectangle is the sum of two lengths(L) and 2 widths(W): P = 2L + 2W section(a) of a triangle is equivalent tyo one-0.5(a million/2) situations the bottom(b) situations the top(h): A= a million/2bh merely prepare those formula.

Answer 7

Take it to a bike repair shop. They have special equipment for stuff like that.
You are not very likely to get it very straight yourself.

Answer 8

YOU don't YOU go buy a NEW one!
