0:00:58 seems like you need to tie down the brake cable
1:04:23 scares the crap out of my pee hole
I skipped most of the middle part of the video. But I do realized one thing, why is there so many uphill? It feels like most part of the video you're pedaling hard. Or was it the type of off road wide profile tire.
On another unrelated note, I would like to sit for this type of video a little longer when, the camera is mounted on the chassis rather than the handlebar. Handlebar video - lots of head spin and puke. Chassis video, you can even fast forward it, normal speed on highlights and make the video looks super cool(I know there's a term to describe fast forward video and slowmo at the highlights, but am too lazy to find one, but that's the wordy idea).
