I just took a look at the site. A few things:
I do like the attitude of the site, however it feels very dark and forboding with all the black. Black can be done well, but in this case, it isn't working.
When first viewing the home page, I do not get a sense of what the purpose of the site is. There is no logo, no brand, nothing that says "this is who/what we are".
With the homepage search option, there is nothing that tells me what I am searching for. "Find your bike" or "Find a bike shop"... whatever
For some reason, the font that has been chosen does not work well with that black background.
Here is something that will help you touch up your site: "Top 10 web mistakes small businesses make"
For your next step, if you want to take this webpage to the next level, I recommend hiring a professional web designer to touch up your site, maybe do a redesign. Something like this for your content would cost under $500.
Let me know if I can help,
