Sorry if this is a re-post. I couldn't find anything in a search. I was watching the Youtube video below, when I noticed at about 0:09 seconds in - there are bike-looking things on the bases of the Stormsurge. Is there any information on these things? In case i cant post the video link (or if it doesn't work) the video is called "Warhammer 40k Open Day 2015" and was posted by "sinzaren".

Sorry again if this is a re-post. I just haven't seen anyone talking about them, nor have i heard any rumblings.
PS. 1st time posting on BoLs!
