Unless you have a great sequence you don't want to interrupt, limit one video angle to around 15 seconds give or take. Try the different angles already suggested, along with things before/during/after the ride. TELL A STORY. Have fun with it. Every ride is a journey; show more than just the road. As already suggested, show the other riders if you have company. Imagine you want to tell your mom/brother/best friend about the journey. What would you capture on that day's ride? If you stop for a while to check out a stream, show the stream. Very memorable videos have 95% character, 5% riding. Or if they have a lot of riding, they change things up repeatedly throughout the video.
