Bosch eBike Electric Motor - Problem with banging / clacking / noises from Justebikes.co.uk

Update: 30/12/15.

It's sad to see so many other people who have had problems with Bosch ebikes and how bad they (and most of the dealer network) are at helping to solve them!

My story this far. I've had 3 Haibikes with the classic motor in. All have had this problem. 2 bikes have had motors replaced completely. The other is now faulty with surging acceleration and aslo not disengaging power when you stop pedalling (very dangerous in traffic!).

Ass a glutton for punishment, I also have 2 other bikes with their new gen 2 performance motor in. The first one developed this grinding noise - https://www.youtube.com/watch?v=k5wQq2_PEgQ - within 6 months. Had to go back to the retailer who said dirt/water is getting in the motor and corroding it! Hmmm, wouldn't you seal a motor on a full on downhill suspension MTB.

The second one has now developed the exact same grinding noise (and it's not even an off road bike - just a touring bike) but so far I haven't had the will to go to get it sorted.

I've also seen that James from Justebikes.co.uk has been posting on forums that, "I'm a liar' about getting my problem sorted. I have and will retain the full communication list with them for any inspection. In the end he said "tough luck" and we won't honour to pick the bike up.

Some time later he text me to say he was suing me! I'm not sure what for but perhaps, "the truth hurts"!

The saga continues ........

Update: 11/11/2013.

The retailer who supplied this JustEbikes.co.uk have now refused to sort out the problem. I have had 100+ emails between myself and JustEbikes.co.uk and it has been a real learning curve of how not to be a retailer. It is worth noting for anyone out there considering using JustEbikes.co.uk that if anything goes wrong then your chances of getting it sorted out are next to zero. My bike hasn't been working now since Jan 2013 - getting on for 10 months to date!

I have had 2 Bosch eBike motors now on 2 different electric mountain bikes.
