So here's the thing about platinum cards...
I tried to use a platinum card to buy a 7000€ bicycle a few months back and I just couldn't do it. None of the bike shops accepted the platinum card provider and none would make an exception to score a certain sale (and since this is an ebike we're talking about, pretty hefty income from maintenance in the future)
It would turn out that the platinum card provider charges such high fees from vendors that at least bike shops in my area won't accept it.
This experience somewhat makes me insecure about the validity of claims that dropping platinum cards would dictate the direction of the technological advancements in the bike industry...
