Review for LEGO set 30531 Sons of Garmadon from brickset.com
“This is a reasonable addition to the Sons of Garmadon range. The motorcycle is very sturdy so is ideal for play and it matches the design of other Sons of Garmadon vehicles, featuring an exposed Technic frame along with a black, purple and red color scheme. I like these... More colors but the Technic frame looks rather awkward and I would rather it had been covered.”
