"Hi, thanks every one for your help, the smart arses can kiss mine. I can't simply take the bike back to the dealer because I live 6 hours away from a dealership (I'm in Australia), I bought chinese because they were cheap, I cant afford much because I'm a single mother and I thought they'd be ok for my daughters to learn on.
Now if I can get some answers to what I'm actually asking that would be great."
Sorry if this gets a little long, but I type fast and have a few minutes to kill, oh and hope it helps tooo
There are some arses that it would be both wise, and smart to be kissing
Anyhow before the positive comes the negative and honestly I hope you have better experience with your purchase than others have had with differnt products from china as it sounds like your trying to do the right thing, and mechanical catashtophe doesnt sound like something that would be easy to over come. Anyway its not all bad (cheap chinese stuff), but way tooo much of it isnt up to par etc.
OK here is the helpfull part, and sorry for the rant above, but maybe just maybe it will be helpful to someone else in the future who is considering a too good to be true deal by making them think.
First off a 50cc engine unless its running absolutely so poorly that the fumes would be killing you and making more unusual noises than you could remember should be turning the wheels and moving those little atvs no problem. So at least its not soundling like you have any serious engine problems to deal with.
My initial advice is not to let things get complicated, or overwhelm yourself. These machines are not all that complicated (really there not, and I mean all of them) and even though I have never seen one of the models you have in person and deff never worked on one I am going to just take it one step at a time and if you do the same it will turn it all into little projects, and not overcomplicate things by being intimidated by the whole package or machine at once.
Heck you may even become mechanically inclined by the time your done
There have been some excellent suggestions so far, but maybe just braking things down will help.
First I have to ask a few questions. When the girls are able to ride them and there moving does the engine sound like its speeding up? Does it sound like the engine is racing but the atv just isnt going anyware, or does the engine seem to be bogged down or just not revving up etc?
There are a few reasons this is important and it will help determine if the problem is coming from the amount of power, gearing, drive, or brake system.
Maybe you had noticed if the brake caliper or ? seemed hot when they were being driven?
The brakes look like they are cable actuated, and not hydraulic disc brakes, and therfore turning the bolt or nut will preset the amount of pressure on them and also how much pressure can be applied during braking. I cant be sure from the pics, but you need to confirm that losening the bolt removes the pressure on the disc, and does not increase it (it should reduce but be sure).
Do the machines roll around freely when not running? If not try and see if you can lift the front and then the rear tires off the ground and see if the resistance from rolling is isolated to one end. If its a drive problem (beaarings in rear, trans or clutch, rear etc) the front end should be free. OK help me out here as I may have goofed a little as I dont see any front brakes in the pics, and if thats correct all that you would be testing in the front is the wheel bearings.
If you installed the rear brake then you can also remove it, and see if there is any resistance with it removed. Maybe even start with this if you believe this is where the problem lies. Dont let the girls ride it, but just test it out on a flat surface by pushing it etc and see what if anything changes.
After you can determine if the brakes are hanging up or not, then we can move forward and find what else maybe causing the problem.
Just by looking at the drive chain it looks like it would be a pain to work with, and I can not be 100% sure on its proper adjustment method, but if the brake checks out ok then I would suggest lifting the rear of the machine and supporting it really good (jack stands are good, but a strong box oreven a milk crate would do the job.
Now I cant be sure but it appears that there are two splits in the rear carrier that should house the bearings and may also adjust the chain. There are two of them and one each side of the rear axle just outboard of the sprocket and brake disc. It looks to use a cap screw (allen wrench is used to turn them) and depending on exactly how they are designed they should hold the carrier and or bearings as well as allow some adjustment.
I cant be sure if this is part of the problem, but if these do house bearings and they are too tight it could or would cause drag or resistence to the axle.
Try to losen these a little and see if the rear wheels turn easy or easier.
Its really little more than a process of elimination.
Sooner or later you will find the problem and all should be well.
Good luck, and if those dont help or your findings change post up the info so that we can get you going etc

Just something for my fellow US riders
Did any of you notice some of the differences between these atvs and the ones sold here?
Seems even though they can mess up pretty badly and be a real pain in the you know what the Consumer Safety group does cause the mfg's to invest a little more into their products etc.

could be you got some bearings with no grease on them.

These little mini quads are everyware, and they are fast when they get going, they are like pocket bikes that can get going for the big kids.
Posted by: fixit
Sorry forgot to put my 2 cents in. I talked to a seller of this type of mini quad and all I got was to check the governer. This may mean the screw on the throttle or some other that the manual may refer to. the clutches are cetrifical thow out types so the reves have to be high. I noticed that the chain can be ajusted by loosening the bolts by the brake and chain sprocket, then turn the axel so the eccentric guides turn. This will lossen the chain.
Posted by: fixit
I think that this is your clutch heating up being over worked. sounds like you narrowed the problem to the axil bearings or shaft. follow 440EX advice further and you will work it out with some allen wrenches I think.

after looking at your pictures again, i see how the chain adjusted , the axle uses a cam adjusment. thiers 2 allen bolts next to the disc brakes and 2 next to the rear spocket, loosen those 4, then you see the hole, right now it shows at the bottom of the axle on the disc brake picture, you can use an allen wrench or you should've have gotten a tool to fit in this hole and you turn to whole axle to loosen or tighten the chain.

tranny oil or something silly maybe? I have no idea.

rzr, not what BEX asked! God, I wish I had a nickle for every time some wise azz gives a smart alec answer to a sincere question.
BEX, I just did a search for Quadard and noticed that the quads have what looks like a twist throttle. Can you confirm this?
If so, someone else may need to jump in as I'm not familiar with these kinds of throttle set-ups. On the ones with a thumb throttle, there is a screw with a jamb nut that you can adjust to give/take away throttle. If yours has this kind of adjustment, just make sure that you make small changes so you don't end up with a run-away quad. Don't want to see your kids get hurt.

I don't think that the problem is a tight chain. How is the motor is running? When you give it gas, is it sputtering or does it rev up smoothly? If the motor sounds OK, then you may have a clutch problem. If the motor sputters, then you need a carb adjustment. I tried to find some close-up pictures to see what type of clutch set-up you might have, but couldn't find any photos large enough to get an idea.

Glad you figured it out! Thanks for replying with the fix. This will help someone that comes here later searching for a fix with the same issue.

truth hurts i know my dealer wold have checked out my machine and been there to help me

Either they are realy lacking for power or the throttle stop screw is turned in to far not letting the motor open up.
Posted by: KINGQUAD450
makes you think it is something that you put together wrong seeing how both bikes have the same problem
Time to start over take everything off you put on and try again
Posted by: axle008
When you put the bike together did you put the rear wheels on. Check the castle nuts on the rear wheels and see if they are wrenched really tight.they should be just snug enough so the wheel doesnt flop back and forth then put the pin back in.The castle nut is under the rubber center cap in center of wheel.Don`t feel bummed out about the negative attitudes of some of the others on here because you can get a lot of helpful info, here. bill2099 got me through a repair over the weekend. let me know what happens. axle008

I have recently purchased a couple of Quadard 49cc atv's for my daughters. I am not the most mechanically minded person (far from it actually!) but I think I managed to set everything up as per the instruction manual but I'm having a few issues...
Basically the things wont move!! I think I have managed to adjust the brakes etc properly and I think the throttles are fine but the bikes hardly move. Yesterday I started them up so my girls could go for their first ride and I actually had to push them a few times because the were just stuck! I don't know how to explain it other than they just won't go. One of the bikes are really stuck, even when I lift the back wheels of the ground the wheels struggle to turn. For the bikes to move at all we need to have the throttle pulled almost flat.
Is someone please able to help me out here somewhere? Can you think of anything that may be wrong/causing this? Maybe skim over how to adjust and set things up just in case I haven't done anything properly.

Hi, thanks every one for your help, the smart arses can kiss mine. I can't simply take the bike back to the dealer because I live 6 hours away from a dealership (I'm in Australia), I bought chinese because they were cheap, I cant afford much because I'm a single mother and I thought they'd be ok for my daughters to learn on.
Now if I can get some answers to what I'm actually asking that would be great.
Yes it has a twist throttle, I have tried adjusting it and opened up the throttle as far as it goes and the bike still doesnt move. I also adjusted the brakes (disc brakes) because I thought they might be the problem but nothing is working.
I spoke to my Dad last night as well as my ex husband and they both said to check the chain, which I did, and there is hardly and play at all. The chains are tight as and probably need to be adjusted
My question is how would I go about adjusting the chain? The user manual is hopeless.
Posted by: BEX
The motor doesnt sputter or anything, it runs well. I have pics of the bike up close but I don't know how to post them on here.

Sorry I should have been more specific. The bikes have rear disk brakes. When I said I adjusted the brakes I meant that I adjusted them by turning the adjusting screw on the brake lever on the handlebars. At the back of the bike where the brakes are I loosened the adjusting bolt then backed off 1/4 of a turn at a time as far as I could go (as per the user manual).

I don't know if this wil help anyone help me any. The technical specifications for my bikes are as follows:
ENGINE - One cylinder, two stroke, air cooled.
DISPLACEMENT - 49cc.
POWER OUTPUT - 2.5kw @ 7500rpm.
TORQUE - 3.5nm @ 6000rpm.
STARTER SYSTEM - manual pull start.
BRAKE - Rear disk.
TYRES - 3.00- 4" (front & rear).
FUEL - petrol, 1:25 engine oil mixing.
FUEL TANK CAPACITY - 1.8litre.
I'm hoping this will somehow make it easier.

Ok I tried to post some pics but they didnt work, I've provided the link to some photos of my girls bikes. I hope it works this time.

Hi, thanks for your info, the bikes were mostly together when they were delivered, all I had to do was put on the handlebars. I'll have a look at the back wheels, thanks again!

Hi, thanks to everyone for your suggestions... I think we might be getting somewhere!

The brakes don't get hot and when not running the bike does not move freely when pushed. The back wheels don't turn as if the brakes are on. The front wheels move fine at all times and can easily be moved by hand. There are no front brakes only back. I took the brakes completely off and the back wheels still do not turn whether the bike is being ridden or pushed.
Now I cant be sure but it appears that there are two splits in the rear carrier that should house the bearings and may also adjust the chain. There are two of them and one each side of the rear axle just outboard of the sprocket and brake disc.

This I am going to try next, thanks 440EX026!
I am also going to try billl2099's suggestion on the chain & clutch stuff.
Thanks so much!
I'll let you know how I go with it.

Hi I checked this out and that area of it is all good. The smaller green bike is worse than the red bike. When I push the red bike the back wheels actually turn and the bike moves when I apply the throttle, it's just really slow too.
Yesterday after work I started up the green bike and run it around the garden at walking pace (not sitting on it, just walking next to it) and there was a small amount of smoke coming from the bit near the engine that turns the chain (I don't know what it's called).

THANK YOU EVERYONE FOR YOUR HELP!!!
I've found the problem with my kids ATV's! After checking out all possibilities that you guys presented I found that it was in fact the chains that were stopping the bikes from moving; they were too tight. I figured out how to adjust the chains and the bikes work fine now.
Thanks again to everyone who left helpful suggestions.

Still not what I asked but thanks for the advice.
Well anyway I wanted to say THANKS EVERYONE FOR YOUR HELP!! After checking out all of the suggestions you guys presented the problem is finally sorted. The issue was being caused by the chains, they were too tight. I figured out how to adjust the chains and without so much tension the bikes are running fine, without any problems.
Thanks again to everyone who helped me try and get to the bottom of this.
