Hello,
I do not have such problems with my Magic Pie I. Just one or two times for the last months, but the spokes are something I check every 15 days by default and a simple tight solves it. I use the "tune" method to know that is tight enough, I tap with some tool the other spokes and hear the tone, and tight the loose one until it sounds the same tone.
This is common at any ebike and as far as I know it is recommended that you check your spokes every month for loose ones. At the Magic Pie the problem seems to be more often because of the large diameter of the motor and high angle spokes, but as I said, just check them every 15 days and no problem so far.
