The motor was replaced under warranty at 6000 miles just on the two year guarantee. The bearing developed play but otherwise the motor was fine but the shop just swapped in a new motor very quickly free of charge (Well done Martin at Ebike shop Farnham).
It will be interesting to see if the bearing on the new motor develops play earlier or later and if the dealership will be able to put a new bearing in or whether I will need to buy a new motor ( hello John got a new motor).
The original battery is still working pretty much identically to the way it performed when new. On my 12 mile off road ride to work yesterday it only used 22% of its 400Wh capacity giving a theoretical range of 54.55 miles from my 9644 mile, getting on for three and a half year old battery.
However this paints a too optimistic picture as I only use eco and actually turn the motor off a lot where the gradient permits on my off road journey to work.
A more realistic picture would be gained from my 10 mile on road home journey where I try to average 20 mph and last night used 32% of my battery giving a potential range of 29.4 miles. But again this has not changed from when the bike and battery was new.
If Yamaha will not provide dealers with spar parts I will have to either replace the bearing myself or buy a new motor when the bearing develops play. From my experience if you look after them the batteries last longer than the motors!
As I am very happy with my bike it might even make some kind of mad sense to buy a whole new same type of bike for all the spar parts it could provide, Battery, Motor, Brakes, two year warranty etc etc than buying new motors and batteries. I paid £1750 for my bike when new.
I did have an issue with the battery when the connecting plug broke as well as a pin connector on the battery. The dealer was unable to help me on that occasion and I had to fix it myself or buy a new battery and charger! I did fix it myself but had to open the battery to solder leads directly to the connectors inside but my new generic 4 way connectors are easier to use and more secure (if uglier) than the original ones and the total fix cost less than a £10 in bits so was somewhat more cost effective than a new battery and charger!
However I have been really impressed with the Yamaha PU motor and system and the quality of the Haibike that has shrugged off the punishment I have given it.
Remember up to half of my miles are off road where the bike gets some proper punishment. I have also had the support of a really good dealer when I have needed them.
