I just picked up a GoPro Hero 7 and its awesome. I had to get it out for a ride on my EUC for a test. As you can see from the video it has great stabilization and even at night it does a great job recording the action.
On this ride I just went out for a quick tour of the Vancouver False Creek seawall down to Howe street and along to Dunsmuir street and home. This is one of my favourite quick rides on my electric unicycle. It makes great use of the seawall, a crown jewel of Vancouver, and our great bike paths that can take you all over the city.
