I believe this is a terrible design for several reasons. First of all, there's very little contrast between the yellow and the white, and the yellow and the text. I also don't like having to turn my head to read the text.
There's one more thing, and that's on the site itself. The way the scrolling is set up... It's really messy. It's an interesting concept to basically have the screen itself morph as you scroll from one page to another, but in practice it does not seem to work well. It takes a very long time to scroll to the next page, especially on my computer, where all I can use is the side of my touchpad. And having a random animation of a bicycle between two pages is odd, especially as long as it is.
And another thing I just noted. At the top, there's a small down arrow signifying that there's more content below, but you try clicking on it and it doesn't take you there. Maybe I'm just assuming too much, but I feel like having an arrow in a pulsing circle is just begging to be clicked.
