Ok, i tested this out and well.
It was VERY BUGGY !! Energica might want to look into this a bit.
I had to retry it several times before it finally took. When it asks for your code and all, it's not very intuitive that it wants the new one / old one etc, and more times than not I'd long hold it like it asked and it double jumped right past the screen into the back to regular driving screen.
Finally I got it to take and now my pin is changed.
**** WARNING ****
To Anybody who has an Energicia Bike, I would STRONGLY SUGGEST that you change your pin code asap.
I should have thought about this myself, common passwords are abcd, 1234, 0000 etc as a first try / default password.
This is not hidden knowledge that the default is 0000.
Until you change this, you might as well leave your key sitting on the bike, I can walk right up, type it in and ride off with YOUR BIKE.
Also as an FYI, I used the pin 0000 to turn the bike on, then navigated to the pin menu and change it, so you don't even need the key to change the pin, just know the pin (oooo)
As a suggestion to Energica - have your dealers tab in a random pin when they sell the bikes, and then tell the customer on that day what THEIR PIN is. Use a julian calendar setup or something it doesn't have to be stupid creative, but would add a better layer of security to the bike. OR HAVE YOUR DEALERS TELL THE CUSTOMER TO CHANGE IT THEMSELVES ASAP, possibly even walk them thru the process AT THE DEALER, so the customer understands the bike better, and if there are any hiccups they are at the right place to FIX them.
Just my 2 watts worth.
