The first thing to ask yourself is "what do I want a visitor to my site to DO?". i.e. are you looking to get them to fill out a form and give you an email address? Do you want them to pick up the phone and call you? Are you trying to get them to look at your bikes? Something completely different?
Whenever you build a site, you should keep the end result in mind, and ask yourself if a visitor who comes to the site is being led to DO that thing.
The site looks fine, but you need to add content and decide what the end goal of the site is.
