Insights

A small Legacy-era 2021 Ninjago entry, Jay's Electro Mech is a 4+ remake whose mass retail run and common Jay minifigures limit scarcity, and while the theme and character recognition support baseline collector interest, frequent remakes and substitution among similar mechs mute long-term upside.

Set Facts

The set includes a posable mech, ninja car, spider, and a golden-sword display.
A Starter Brick is included to provide a partly constructed base for building.
The set is a re-imagined version of 70754-1 Jay's ElectroMech from Tournament of Elements.

Collectors

Investors

The Brothers Brick

“One of the two minifigures is (somewhat) exclusive to this set, there are unique and rare parts and brand new colors for other elements. The build is easy (as it’s supposed to be) but still kind of fun. If you’re a four-year-old Ninjago fan, you’re not going to be unhappy... More with this set. If you’re an adult collector, you might want to wait for a sale or just source the new parts elsewhere.”

Full review at www.brothers-brick.com

BrickFanatics

“The mech also introduces two new leg pieces, with stud attachments at the knee and one point of movement at the hips. The bottom of this new piece provides a four stud attachment point. No doubt the LEGO community can figure out some inventive uses for this new element.”

About Ninjago Legacy

The Ninjago Legacy subtheme of Ninjago is dedicated to re-imagining concepts used in classic sets. The first wave consisted of re-imagined sets from Seasons 1 and 2 and released in early 2019. The second wave, released in 2020, consisted of sets from the pilot episodes and Seasons 2–4. So far there have been 5 waves, the third wave consisted of sets from Seasons 1 and 3. The fourth wave focused on sets from seasons 2–5 and the fifth wave consisted of sets from the pilot episodes and seasons 1 and 5. Rather than conform to a specific season, Legacy is based on the Ninjago franchise's early history, with the first wave celebrating the television show's tenth season and 100th episode.

Legacy was introduced in 2019 and currently consists of 37 sets. As of today, 71741 NINJAGO City Gardens is the most valuable Legacy set with an estimated new/factory sealed value of $400.
