Best LEGO Mech Sets – 2020 – Get Creative With Bots

When it comes to childhood play and learning, nothing is as fundamental as the Lego. Individually, each Lego brick is fuel for the imagination. Collectively, the multi-colored pile of Legos is a play feast and learning opportunity for any young, creative mind. However, Lego mech sets give shape to Lego’s infinite possibilities, prompting kids to learn, snap, and create while rewarding their efforts with some of the most awesome contraptions ever devised.

Piece count

The primary consideration for choosing any Lego set is in the piece count. For younger children, you should select a piece count of around 200 to 500. However, for very young children, it might be better to find a set with 100 to 200 pieces. For older children, higher piece counts allow for more interesting complexity and greater challenges.


Many Lego sets come with pieces smaller than the average Lego block. In order to ensure your child’s safety, read the package warnings. Things such as missile projectiles are guaranteed to be small beads that a young child can swallow or choke on.


All Lego Mech sets come with extras, but not all mech-set extras are equal. You should look for ones that include such things as a large assortment of weapons and a variety of Power-Burst elements.


This is a main feature for mech sets. However, not all mechs allow for the same variety of poses. For instance, some mechs allow for just arm and leg poses while other mechs include torso, shoulder, and finger poses. To ensure the most enjoyment, you should look for sets that allow the final build to be posed in a variety of flying, attack, and running poses. Multiple poses allow for your child’s play time to incorporate multiple story lines as the mech hero flies or fights or rescues other Lego characters.


Mobility does not only refer to being able to pose a character. Mobility in a Lego set involves a degree of interactivity not possible with sets that have no moving parts. For instance, the best sets have cockpits that open and close as well as wheels that rotate. Cogs might turn, and levers might move up and down. Wings might adjust for soaring or fold for ground fighting. Finally, weapons might cock and fire and offer real functionality. When it comes to Lego mech sets, fun is synonymous with moving parts.
