Right Url To Show The Root Of The Products Catalog?

[canelones]

I guess this is a very newby question, keep in mind that this is my firts Prestashop installation.

 

I created 2 product categories:

1. Cars
2. Bikes

 

I need to create a link to a page where I can see all products for both categories Cars and Bikes.

 

I get the links to show them in 2 different pages but not a single link to show them in a single page.

 

thanks.

I found this module: http://addons.prestashop.com/en/search-filters/17829-show-all-products-on-given-page-link-.html

 

Is this the only way to show all products in a single page?
