I've got one of those and after a few years i can give some advice to those thinking about this as a ebike.
Wheel bearings. They are loose ball bearings in the shimano hub and if you don't regularly servicing them you'll be replacing the wheelset. Like me..
Front cog. The mini sprocket wears so quick once worn it chain sucks really badly and you risk snapping the chain if not careful
I've just replaced all the linkage bearings again set yourself to do them at least every year, they have alot of double bearings and if they've failed knocking them out causes the races to break open resulting in need to cut them out
I'm not sure if the newer one has improved the cable routing but you'll be swearing at it when you need to replace the dropper cable as it routes round the motor through a tiny hole.. you need to take the motor out to replace
Other than that it's a great bike, if not a little on the heavy side
Anyone wanting to buy mine
