Good to know!
Well I just sent my Strida EVO for a basic servicing - only as I am also swapping out some parts (customising and giving it some love back since I been riding my other bikes of late - and it’s been 1 year). I use the EVO as one of my exercise bikes - hence 3 times a week - pending good weather and if I can wakeup early enough since it takes me approx 2.5 - 3 hours for the 50km 
So on that note - I am aware that not all moving parts will last forever - and I am totally HAPPY to pay for servicing etc - It’s just that I am baffled or intrigued that I am supposed to just “leave it alone” - hence I am holding my breathe wondering how long this KS drive will last on my EVO.
Thanks for the insightful sharing and information.
