(1) Yes! The HERO7 White comes with a Frame that allows you to connect it to our mounts, and it comes with some adhesive mounts you can use with the camera. (2) Which accessories you get really depend on where and how you're planning to use the GoPro. If you're going to be around water, check out the Handler or the Floaty. If just for everyday shots, our 3-Way, Shorty, or Jaws mounts are great. (3) The GPS allows you to tag where you are when the photo or video were made. You can use that data to overlay gauges on your videos to show how fast you were going, the route you took, etc. You don't need to be connected to wi-fi to make that feature work. The camera picks up the GPS signal on its own.

The Dual Battery Charger comes with an extra battery for your GoPro, but it does not have its own internal battery. It connects to a power supply using a USB cable, and transfers that power into your GoPro batteries. You can connect the charger to an outlet using a power plug (ex. an iPhone plug works great), or you can use other USB power sources like plugging the charger to a laptop's USB ports, or some external power packs.

You do need to be connected to the Internet in order to post out to Facebook from your phone. If your hot spot allows you to do that, there's no need to be on a separate wifi signal.

A lot of motorcycle riders like to use our Handlebar / Seatpost / Pole Mount. It can lock in most handlebars or other points on the motorcycle, and still allows you to easily remove the GoPro between uses.
