I had a Spesh Levo and loved it, now have a Spesh Kenevo and love it even more
I kept my normal bikes for around a year but never really used them all the time the e bike was sat there ready to go
I ended up selling my Transition Scout, Patrol and TR500 as the Kenevo can do everything they could do, 30 mile xc rides to full on DH sessions it just eats it up
I do like the look of the YT but the only thing that puts me off is lack of UK warranty repair, if there are any issues with the motor or battery the whole bike has to go back to Germany to be fixed
With Specialized if you use the right dealer (aka Berkshire Cycles for me) your bike is fixed the same day whilst you wait!
