Hi
Kiox is a bosch unit but the frame mount is Treks
I did the mod to my 7 but mounted it on the top of the steerer which the kiox kit you buy comes with anyway
Best advantage for me was battery percentage instead of 5 blocks
Theres other features but i tend not to use them its also handy being able to adjust your wheel size if you put a 27.5 on the rear

Kit below but obviously you would get it your side .
