That sounds cool, yes, multiple angles could potentially make the videos more interesting, need to figure out how I can rig up a rear mount on my '04 CBR1000RR.
Talk to @HippoDrone - he's got fancy mounts with eyelets in them to mount cameras to. He's done all the legwork, so sit back, watch some of his how-to vids, and order stuff off Amazon
If it's got a round-ish bar anywhere, I bet you can mount a camera to it. Or a flat spot for a sticky mount.
When I hit the big time, I'm gonna hire a two-person crew to ride alongside me and have like 14 cameras on their bike and a couple of handhelds for the passenger to work, to record me riding. My vlogs will be EPIC!
