My NCM Prague is now about 2 weeks out of warranty (Typical!). Today I noticed a good few mm of lateral play on my rear wheel. It’s enough that if you grab the rim while the bike is on the ground, you can feel it move pretty easily on the axle.
I took the wheel off and noticed nut on the non drive side, I tried to tighten this and it immediately sheared, which isn’t surprising as its barely a couple of mm thick!
So, I wonder what my prognosis is here? Is it likely that a replacement nut, (perhaps a marginally thicker one?) would tighten and solve the problem, or is it likely to be a bearing issue? I am sure I have read that bearing in these motors just aren’t designed to be user serviceable, and that a motor would be more cost effective?
if it comes down to that, where can I buy a plug and play replacment wheel and motor, do I have any options in terms of compatibility?
Any help greatly appreciated!
