I'd suggest that you give some thought to planning your videos if you really want to make something entertaining, and note that the the best videos tell a story in some way. If you just want to collect bits of footage from rides that's fine, but a really interesting video probably won't come of it. You also have to include more off bike shots. That means you have to break up your ride and do shot set ups, but that's the price.
Well done for having a go though. Check out this guy's work. You don't have to aim for the same production quality (and he's a bit cheesy at times), but look at how he's put them togther.
Cheers
