I can’t figure how to use another language than English, although usually it’s quite simple. So please show me the problem is not in the template pack by making a clean install with the bike template and then make for example the German language work (that language is already installed in your template), don’t care if the contents are still in English, I will understand, and don’t forget to supply me with the login so I can see how you managed.
All the fine multilanguage manuals available (http://www.slideshare.net/erictiggeler/creating-a-multilingual-site-in-joomla-joomla-3-beginners-guide-eric-tiggeler), http://www.templaza.com/blog/how-to-create-a-multilingual-site-in-joomla-3/68 and http://www.templatemonster.com/help/joomla-3-x-configuration-multilanguage-site.html) don’t seem to apply to this bike themplate pack. Of course I did assign the Dutch memu to the right template.
I opened a ticket for this issue, to no avail, so probably it’s quite difficult.
