Suggestions: I'd avoid cropping a side of the product - img 1 (crop both sides - as you did on img # 5 or no sides at all)
Love the treatment of it all - some people go with an earthy feel to relate to the use of the bike. Either way is great!
I'd suggest putting the logo + url at bottom right - ends the page
Love your work!
Contrary to the previous reviewer I like how you have cropped one edge of the bike in image 1. it adds to the edginess of the design. Slightly goes against the grain, which seems on-brand.
I like what you have done in image 3 with the lines, although they don't match the bike too well. might be nice to take some of the design elements on the bikeframes and use them in the ads.
Nice work.
Sorry i forgot to say something: you will make your design better if you focus more on the text something like making the upper text bold or more bigger as overall try to increase the letter spacing for text descriptions text to make your eyes more comfortable.
its really nice design, what about adding a stone background on the footer by a nice way ? I uploaded an image for you to got the idea.
good luck.
