iMovie.
I'm working on one from the show today. Two cameras, multiple angles, external microphone. It's a lot of work.
One rule that I try to adhere to with riding videos is no clip longer than 30 secs. No matter how fascinating the scenery might look it gets monotonous for the viewer. When I can I'll break it up with a cut or even better a different camera angle.
The V11s are tough as there aren't a lot of places to mount the camera. The older bikes are easier as there are frame rails and other things. But you may want to look other mounts.
