Thatwoul be a used bike.Call the mfr or customer service and they can give you official details.

Eh? Maybe try reading the caption of your posting. The GS might say something about model or make but serial number usually covers date, place, and order off an assembly line somewhere, if that much.

Those are ball bearings. If they are out of the wheel you have a complex problem and repair. I suggest you take the wheel to your local bike shop.

the gear that needs to be replaced requires a special tool. You can get one online whereever you buy the gear you should also be able to purchase a splined socket to assist in getting the old one off of the hub. Might I suggest ebay.com?

raise the back of the bike and put the wheel between the rear stays place the chain on the freewheel, and pull the wheel back and then just tighten the wheel nuts.

More info Please!

undo the lock nut that is on the cable holder on the brake. turn the case out to adjust the brake lock up nut when done.

you will have to purchase new one unless you can somehow salvage the old one and i have never seen it done.its just a little star like wedge with a screw hole very cheep.

The silver washer will go between the frame of the bike and the peg. Then the nut for the wheel bolt will go into the peg and screw on from the inside of the peg. Unless they are solid pegs in which case you will put the washer on first still and then screw the peg on as if it were the nut itself.

Retrace your actions. It's something you did, right? LOOK. Is the wheel in straight?

Web search "install rear wheel"

You could also just use a search engine - "noise crank bicycle", for example.

you can drill holes in the handlebars through the center piece, or chop off part of the seat post that isn't being used and drill holes in the seatpost where it is used. other than that buying lighter parts is the only way to go

The 2010 Stereo speaker require a 1 1/8 gyro.

Yes,as the cable is tighten (brakes applied) the metal slides alongthe cable. hope this helps

Take it to a bike shop, you are dealing with a trick bike. You do not want to have the brakes fail from a bad adjustment, unless you have the right tools and know how, because you are having to deal with the spacing on the detangler and it takes skill to do it right, do not do it yourself. Someone can get hurt in a diy.

Your wheel is probably bent and has to be trued. You cannot adjust your brakes without the wheel being straight. You will have to take it to get serviced unless you have a truing stand and a good quality spoke wrench.

Hi MonkeyManTim

Firstly, remove the centre lock nut on the stem. This loosens the stem/headset. Pull the handlebars up and rest them next to the front wheel, make sure the brake cables aren't being stretched too much.

You'll see there is a locknut on the headset (at the top of the frame/top tube where you pulled the stem from) and loosen this (might need a massive spanner!).

Pull offthe toppart of the headset, ball races and lower part. Replace with the gyro bottom and top parts. Grease the ball bearing if they aren't already!

Slide it together, fit the stem and you'll notice the brake lines that come with it. Undo the rear brake, run the splitter cable from the front lever to the top half of the gyro, same with the bottom half. I found putting some padded stickytape on the bars helped here as the splitter cable would 'ting' off the bars.

Undo the front brake and run it through the stem hole, through the forks and cable tie it to one fork leg.

Test the brakes, adjust where necessary and on you go pulling bar-spins for fun. Please don't land a jump with the bars half spun, it hurts....a lot!!

There are two ways to adjust handle bars on a bike. It's either by using a hex key at the top of the neck or loosening the octagon nut at the base of the neck near the body.
