I wouldn't put my phone in a solid mount like that. Phones are not vibration proof and now you've mounted it to a solid piece of aluminum bolted to a vibrating bike. It may not skip down the highway, but it probably will scramble the insides just the same
Magellan gps,,, hard mounted to bikes... died in 3 months
second Magellan... vecro-ed to mount. died in 5 months
third Magellan... 2 sided 3m tape.. died in 2 months.
forth Magellan.. 2 sided and vecro... 11 months..
all covered under warranty.. over 3 different models..
my Garmin 2597 .. is vecro to hard mount... 6-7 years no issue...
just saying... a high dollar phone.. NO WAY.. even if it never gets loose.
vibrations... road shock.. high wind.... intermittent rain... even a good splash for a water spot on the road.
CHUCK HOLES... pot holes... unapproved road detours...
your bike, your phone, your money... your loss.
