With out seeing a bike mode I don't make to make assumptions...okay thats a lie.
It looks to big to be a scout so im leaning towards HA Arcee with skids or FAB arcee.
I don't recall there being a scout version of deluxe toys for the ROFT movie or the old movie(am I mistaken??)
Also the two feet seem to be a way to combat a lack of side car, which HA arcee also does not have and I doubt nether will FAB arcee.

EDIT: Ok I looked at the photos again and the transformation looks alot like Animated Prowl and therefore too complicated for a FAB mode.
