Since we do not have that many MP3s here in USA it is not easy to find accessories for them. I've been checking on the Internet and I guess the only solution is to have a friend or relative that lives in Europe (Italy would be ideal), and ask that person to buy it for you and ship it to USA.
I have a few items on my list for my 2016 MP3ie 500 Sport:
Racing foot-pedals kit.
Multimedia & GPS support kit.
Saddle-handlebar top mechanical anti-theft device.
Any idea where to find these here in USA?
