I hope it won't fail again! Im not faulty, that's not exactly what I can say because I am the one who opened the engine after a terrible overheating I had to do that. I had to put some new teflon grease onto the nylon plastic gear which is in good state. Here came the bad thing : this nylon gear and pinion are held in place by circlips. I realized that they were in poor condition, but I still put them together as is. And they failed.
As many mid motor owners here already know, I personally find such Mid Motor installations, any of them, to be generally poor in design, and poor in support from the manufacturers, and I can only say to anyone considering buying one, DON'T!
The biggest single failure is that all power, both human and electrical, goes through the single chain, causing extra wear and sometimes breakages.
These breakages can in some cases cause a really long walk, where conventional hub designs, have a simple fail safe design, that allows pedaling home if the motor/battery fails, or riding home using either the PAS or the hand throttle, if the chain breaks.
I am really sorry that you had to experience this problem, but I also thank you most kindly for bringing it to our attention here on Pedelec, and telling us all exactly as it was.
You and all the other owners/users of mid motor designs, deserve far better from your invested money and time....
Let us all hope that in he near future, the designers and sellers start of such systems manage to get their act in order, and are able to supply reliable systems at reasonable prices, for anyone.
regards and thanks again for your posts and pictures.
