G'day Nuvola,
I see you have a 5 speed sprocket. You may have to replace it with a smaller one, perhaps a 3 speed, even a single speed would do. With the power assistance of the motor you wont need all your gears now anyway, especailly with 1000w. I have a different brand hub that is only 400w and I could only get a single speed sprocket to fit, but I still have the 3 front gears, although I don't use them. I can still go up hill in the highest gear as the motor does most of the work. Hope this helps,
Muzza.

I don't undestand why GM sell a product that's wrong!
I know I can change with a one with only 3 gear, but why should I do this!!!
I've to pay for it!

G'day Nuvola,
So the gears came with the motor. I don't actually have a GM hub (just their battery), so perhaps someone who has one may be able to help better, but perhaps the gears are not threaded all the way onto the hub yet. Just a guess. From the picture I can see just a bit of the shaft is sticking out from the nut, I think it would still hold the wheel if say 2/3rds of the nut could still be screwed in after it was put onto the frame. Also check the dimensions are the same as on the spec sheet: http://goldenmotor.com/e-Bike-DIY/FRONT%20AND%20REAR%20WHEEL.pdf (http://goldenmotor.com/e-Bike-DIY/FRONT%20AND%20REAR%20WHEEL.pdf)

OOPS looks like somebody screwed up on that one. My GM 500w has at least .5 inch left over after everything is put together and the bike is down the road. Although I have the 5 speed freewheel the gripshift only adjusts for 4 and I only use 3 so yours is still usable as said in previous posts but that's got to suck to spend good money and get something like that.

NO WORRIES NUVOLA your fork should only be about 4mm thickness .....first remove the bolt and all spacers etc, add the fork first, then a spacer washer, then the torque washer (with the tab down facing towards the hub), then the last spacer washer add the bolt and tighten...should all fit (I suppose you could leave out the last spacer washer?) Wheel nuts should be very tight! Also check & tighten spokes as well! OK....Cheers & good luck.[quote

I had a short one too, with one of my axles :|
A bit longer than yours though, and I have a thick alloy frame. I angle grinded the inside washer thin and omitted only one torque washer, however please be careful when omitting one torque washer.
Yes you don't need any gears anymore.
IMO maybe send it back.... But that sepends on transport costs or how bad you need the wheel.

Looks like you might be using the stock axle nuts. Mine were not threaded straight so when put on the axle they wobble real bad and when tightened up they would not lay flat on the washer. Not a very good thing when you want to hold something flat together. Your pic makes me think that yours may be the same, carefully worded, ;^) as things look to not be tight at the bottom of the nut and washer. At least check it out could save you grief later on.

Yeah I had that going on too it was going to do up skewed. Before I did it up I made sure it went on straight, having that little more space made all the difference though.

I have the same motor on my Trek Navigator and have plenty of room! Even had to add an addition washer! I think that the problem is with the bike and not the motor! Depending on the type of bike and frame material, You may be able to carefully spread the two forks enough to make room for the motor. And... No, you really don't need all those gears unless you plan to drain the batteries and peddle home!
Good luck!

look other side, there a lot of space, it seems hub itsn't just centered!
do you think there an easy way to move it from left to rigth?
-
Well not the greatest of pics but this might help.

G'day Nuvola,
Can you take the nuts off the side of the first picture and take a picture looking into the gear for us so we can see if it is off centre. See picture below for more comments.

I've to remove gear to check my motor against your photo, and I'm not sure to have hardware tools to do it.

No I didn't say the gears, just the nut and washer so we can see past then and see the shaft.

I would need to take the wheel off to get a decent shot of the the pic you request. I have only one good arm now at about 70% to work with at the moment so a bit hard to do. I can say however that on the wire side with the freewheel you will need a washer to extend just past the freewheel so the dropout will clear the frame. On the other side you will need a much longer spacer or washers to extend out just past the point where the flats are on the axle. I had to spread my drop outs apart slightly to make things fit once this was done. The spacers that extend into the motor need to be centered before you tighten things up or you will get a grinding sound until things wear in far enough to not touch. This link to the ES forum has more pics and info that may help you. The GM site has links for the install of the motor. Good luck.

I am not sure that you guys see just what he is talking about.
With the stock nut and included washers on the axle on the
freewheel side the axle is flush with the nut.
It appears that they left too much room on the wired side
at the expense of the freewheel side.
It seems like this is a warranty replacement issue.
Has someone taken a rear wheel apart enough
to see if the axle can be shifted over?

Yes if it he cant manage it from this point its a waranty. Unfortunatly he scratched up the hub housing with the gear changer, I have a feeling this will be over looked if he returns it.
Yes have taken it apart and you can not shift the axle. Its welded solid.
Here this may help some...

I think you should cut a part of your cover,but may you can't install your brake
Before you order your product,you should know the size of this product
Now everything of goldenmotor has a PDF drawing, instruct this product.
-
please pay attention that pdf is the front motor schema because it doesn't have gear!!
so it is unusefull for rear motor like mine!
anyway GM should check what it produces, because when they assemble it or just when they project it, they couldn't make a big error like this!
anyone can see that there's no enough space for fork!!

That PDF is for a rear motor like yours. The gear is just not shown and need not be. Did you ever get it together? Did you omit some washers to make it work? You can also turn the motor around and install the freewheel on the other side if I am not mistaken as the direction of spin can be changed with a jumper wire. Yes I know that puts the wires on the same side as the derailleur but it should pose no serious problem as many motors come that way.

Please look at the original picture it's pretty plain that the axle is way to short on one side and is NOT in spec as in the PDF picture. He is but one of several with the problem it has nothing to do with the bike it is being installed on. Most are working around the problem by leaving off washers ect. not only should this not have to be done it is dangerous as the tabbed locking washer is often left out too. This is another QC problem for GM to take care of can you do anything about it? I am waiting till I see good 48V motors being put out before I buy another which I fully intend to do as my 36V GM has held up very well and is going strong with well over 2000 miles on it.
Oh by the way it is good to see some support here on the forum I am expecting Quality Control will get better now as you have some good products to offer. Thanks

I'm finally using my 1000W motor
a friend of mine build for me a 48V30ah lithium batterie and I discovered a new quality problem!
due to hub decentered, all motor and wheel is moved to left and this cause that left VBrake get touched by wheel while rigth one has too far.
I had to remove all my rear breakes to avoid contact between wheel and rear brakes!
I'm very unhappy.
Anyway I reach 52.5 km/h with a 15kg batterie and my weigth is near 100kg!!
Top speed and acceleration is soo fast that I'm changing front brakes system to a disk brakes system
