thanks for the assurance. I just updated this morning, it well well. I have an iPhone, and the update took approximately 5 min.
I got burned before with firmware updates, where manufacture disabled things on purpose. I think it was a Lexmark printer, where after the firmware update now you must replace ALL your ink when only your black ink is out... ever since then I have been skeptical especially why providing firmware update on a 4 yr old product lol.
all in all, I love my Explore E3, that bad boy has 7300KM on it, I took my son in a Thule trailer to so many places thank to the motor. This is why I really don't want any unnecessary risk that might break my bike especially by a firmware update. However, I wouldn't be able to use the app to check the battery health, mileage ...etc without updating the firmware. I really think Giant should allow us to access the regular function of the ride control app without forcing you to upgrade to the latest firmware.
