I think his point is that there's nothing very photographically interesting about the first half of the photos. It just looks like you're trying to show off your bike without much attention to the actual photography. But if you want a C&C:
The first three aren't really that compositionally interesting. It's just a shot of a bike without an interesting angle, etc.
The 4th shot (the close up of the wheel) is probably the best of the bunch.
The last two are interesting ideas, but not very well executed. It looks like you wanted only the tree's leaves to be green, but there's some green left in the grass in random places. Also, I'm not sure why you chose to leave the background colored. Usually you want to leave the main subject colored, and the background unsaturated. Leaving the background colored draws the eyes away from the point of interest (the bike). Also, the 5th picture is out of focus.
