I like your yard!
Nice to be able to go for a spin and test stuff from your garage. Can you access a lot of trail from your house?
Video looks good. These types of videos look OK on YouTube because the high motion content is relatively small. Helmet cam video is probably the most difficult type of video to retain quality becaue of the large high motion content, and the detail in that content (woods rushing past). High motion, high quality demands higher constant bitrate.
