Little feedback from someone who used to produce web content for a bike company:
1) The pace of the music doesn't match your content. Generally speaking your music selection should compliment the action/story in tempo. This music is much better suited to really fast paced action. Not that your music selection has to be an entirely different genre - okay, maybe it does... speed metal just doesn't go with picking your way up a rocky trail... but you should at least find something that doesn't clash.
2) You can pick up the pace of your video by using shorter clips. Cutting more often between different shots will give you the opportunity to A) use more angles B) use faster paced music C) highlight just the important parts of the action and D) generally make your edits more interesting.
3) Going off #2, use more angles and don't zoom. When you feel like you want to zoom to change the shot, don't. Move positions. Physically walking forward or backward is far better than zooming. Better yet, change positions entirely. Cutting from one perspective to a similar perspective is jarring for a viewer. Change to a perspective that is significantly different.
Here's a good article about some shot types. Keeping all these in mind when shooting will give you much more latitude when editing.
4) Try and keep the camera still. You don't have to use a tripod or anything, but do your best not to move the camera around much at all. Unless you have a gimbal don't walk around while filming. Not only can it be disorienting for viewers, if you're focused on not tripping over obstacles then you aren't focused on keeping whatever you're filming in frame.
5) Get some people talking. It can be casual on-trail or it can be before/after (both!). It doesn't have to be a lot, but engaging with the people there and getting information about what's going on is a very big part of why sooooo many popular channels/shows use both setup and on-the-spot commentary.
What's already been said about music/ambient mix volume is definitely true, and there's lot of other fine details to go into, but the above will be plenty to keep you busy and go a long way to improving the videos.
Hope that helps!
