I spoke with 50 cycles about this issue and they came back to me immediately via e mail - and gave me permission to quote the content here. Its given me some reassurance and good customer service. As said on the forum putting on the miles is the test so either way I'll put an update here in months ahead. I've read up on the comments re bearings and don't know enough about mechanics as to whether a 'software update' as quoted would resolve it. The bottom line is - at the moment the bike is going like a dream and very pleased with it.I wish I'd read this post before my purchase last week. Is this a factory fault on all Evo motors ? Do you have a link to the you tube videos? The bikes have a 2 year warranty though.

"The Impulse Evo & Evo RS motors have been very trouble free for us - I think I've seen one back in for repair in the Bristol store since their release in August. The "clacking" issue that is mentioned on Pedelecs on occasion is pretty much solely with the Impulse 2.0 motors, which has been rectified with a software update. With regards to that user's comments - it seems like he is based in Australia. At 50cycles, we would never open up a motor whilst it is in it's warranty period. Even if we know what is causing the issue - we will not open up the motor, it will go through our warranty procedure and sent back to Germany. This is the quickest and most effective way with dealing with any issues with motors - and current turn-around from initial contact for the Bristol store is less than 24 hours to get you back on the road should anything happen".
"Just to put your mind at ease, to keep your warranty valid, we require no proof of servicing especially not every 1000km. As long as your are still in your 2 year period (10 years for the frame) we will be able to process a warranty request. However, I still recommend at least annual servicing of your bike. Run the bike through winter, let the crud build up then bring it in to us in February / March to strip everything down and make sure it runs like new again." Unquote
