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

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?

[biohazardman]

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.
