Motorbike is much more complicated... true emtb is for robbing people. I have cube stereo for 3.5k and lets be honest.. its pretty crap. Not worth that kind of a money.
And yet you bought it - which kinda undermines your position..!
"Worth" is rarely directly aligned to material value. We buy eMTBs primarily
for what they can do for us, not for the monetary value of their constituent parts.
See how much of the Mona Lisa you'll get if you're only prepared to pay for the value of the canvas and the paints used..!
(Complexity
per se isn't that important either - a mobile phone is a monstrously complicated thing technologically, and you can get them for next to nothing.)
It's just the same for motor bikes: for many (most?) riders, a Honda Cub will do the job of getting them down the road: so why buy a - say - a Ducati V4 Superleggera?
Because of what it can do for the rider that the Cub can't... And that is what makes it "worth" the astronomical (£86k UK) price of the thing.
We're paying for
the pleasure of an eMTB, even when that price handily outweighs the simple material cost.
I've got some friends who will happily pay a lot more than I paid for my SL, to go skiing for a few weeks; or to spend time cruising around the Caribbean.
I think they're nuts, they think I'm nuts. And each of us think
we're getting the best bang for our buck.
Funny thing, "value"...
