Hi, i am looking for help with trying to get into my motor hub,
i have only done about 200 miles on it but today the front wheel sounded
like a golf ball in a washing machine !! and was very judderery.
I am thinking the gears have gone but cannot get the damn thing open..
The model is a front wheel motor, part AKM-13.0.
Thank you Jayne.

More likely to be a bearing as such motors, to the best of my knowledge, do not have gears.
If you know your way round bikes, you might be OK, but you sound "inexperienced".
I would say the same to any male. or female in your predicament.....
Why has the bike got no guarantee if only run 200 miles? That is the right way to go.....
To disassemble such motors often needs special tools......and at least a degree in mechanical engineering.....
I am really sorry that you are confronted with such problems and that I cannot be much help as I do not know this motor!
I really think that a good bike shop is the best way to go if you have no guarantee.....
regards
Andy

What sounds like a motor problem is 9 out of 10 times an electrical problem.

Put the motor back in the wheel and turn it by hand. You should feel it whirring a bit when you turn it backwards with some slight resistance and maybe a bit of notchiness if you turn it very slowly. In the other direction, it should be relatively free, so spinning it should show if there are any bearing issues. The motor is faulty if you feel uneven resistance or obvious bearing noise or roughness, but that would be very unusual in a motor that's only done 200 miles.

The most common cause for what you experienced is the motor cable not properly connected, followed by a damaged motor cable, then a blown controller. Damaged motor is at the bottom of the list, though yours looks like an Aikema version of the Xiongda yw06 that may be a bit more fragile than most. It's difficult to judge the size from the photo, especially because it's a small wheel.

Edit. On second thoughts your motor is the Aikema version of the Q75, which is a fairly robust motor.
