JMBricklayer is a Shenzhen brand of building sets for adults, many with motors and a remote in the box. This comparison covers who makes it, whether its bricks fit LEGO, what an independent review found on quality and instructions, how its range differs from LEGO's, and who should buy which.
JMBricklayer is the alternative brand to look at if you want a motorized train or construction vehicle with the motor and remote in the box, or a large display subject LEGO does not make. LEGO is still the choice for licensed subjects, for LEGO's own designs and for resale value. The bricks fit together, but the experience is not identical: an independent review found JMBricklayer's long thin pieces flex more than LEGO's. This comparison covers who makes JMBricklayer, how its bricks compare, how its range differs from LEGO's and who should buy which.
Who makes JMBricklayer
JMBricklayer says it is owned and operated by Shenzhen Aifu Network Technology Co., Ltd, based in Shenzhen, China. It sells building sets aimed at adults under its own themes, including The Age of Sail, Military World, Construction Machinery, Mecha Warriors, Fantastic Animals, Art Classics, Book Nook, Fairy Tale Town and Haunted Builds, plus remote control trains and construction vehicles. It sells through its own store and on Amazon.

Do JMBricklayer bricks work with LEGO?
For ordinary building, yes. JMBricklayer states that its bricks are 100% compatible with all major building block brands, and its product pages use the phrase compatible with major brick building systems rather than naming LEGO. The independent review we found, The Gadgeteer's 2022 review of a JMBricklayer 3 in 1 Medieval Weapon kit, reported that the pieces were totally compatible with LEGO and that the clutch held, so models stayed together unless pulled apart.
The same review noted the one difference you would feel: longer, thinner pieces such as a 1x8 plate were noticeably more flexible than LEGO's. In a large span or a load-bearing beam that matters; in a wall or a decorative detail it usually does not. The electronics are a separate matter. JMBricklayer's motors, battery boxes and remotes are its own system and do not plug into LEGO's Powered Up hubs, so plan each motorized model around one brand's power parts.
Quality and instructions
The Gadgeteer found JMBricklayer's instructions very similar in style to LEGO's, with a few images that needed to be rotated and one sub-assembly whose order caused trouble. It reported no missing pieces in its kit and noted that JMBricklayer says it will send missing pieces if a set is short. Its overall verdict was that the set was an excellent alternative to LEGO Technic for its type of build. That is one review of one kit, so treat it as a fair picture of the brand rather than a guarantee for every set.
LEGO's advantage is consistency: the same colours, the same tolerances and the same instruction style across decades of sets, and a replacement parts service for missing pieces. That is what the higher price buys.
Price
In The Gadgeteer's review the JMBricklayer kit cost roughly 20% less than similar LEGO sets. The bigger difference shows up in motorized models: many JMBricklayer trains and construction vehicles include a motor, a battery and a remote, while most LEGO Technic sets are mechanical and LEGO sells its hubs and motors separately. LEGO's current prices are in the cards below and come from our catalog when this page is built.
Where the ranges differ
JMBricklayer leans on subjects LEGO covers lightly or not at all: sailing warships, military vehicles, large mechanical animals, and a wide range of motorized trains and construction machines. LEGO's strengths are licensed subjects and its own designs. These are the LEGO sets that compete most directly with JMBricklayer's best known categories:
The Technic Volvo EC500 Hybrid Excavator, LEGO's motorized construction flagship, with a motor and gearbox driving four functions. The direct rival to JMBricklayer's RC excavators.
The City Police Train Heist, a Powered Up train with a working locomotive and an oval of track: LEGO's answer to a JMBricklayer RC train, aimed at children rather than adult display.
The Technic Porsche GT4 e-Performance, a remote-controlled car run from the LEGO CONTROL+ app. Expected to retire on December 31, 2026.
The Technic McLaren P1, a licensed 1:8 supercar with a gearbox and moving pistons but no motor, the kind of licensed car JMBricklayer cannot offer.
The Icons Titanic, LEGO's large ship display model, for anyone weighing JMBricklayer's Age of Sail ships against a LEGO ship.

Resale and support
Retired LEGO sets have an established secondary market, and in our market data many sit above their list price years after they retire; our LEGO investment guide covers how that works. Alternative brands do not have a comparable resale market, so buy JMBricklayer to build and display rather than as something to sell later.
Who should buy which
- You want a motorized train or construction vehicle with the electronics included: JMBricklayer.
- You want a subject LEGO does not make, such as a sailing warship or a large mechanical animal: JMBricklayer.
- You want a licensed car, Star Wars or Harry Potter: LEGO.
- You might sell the set later: LEGO.
- You are buying for a young child: LEGO, whose age marks and play sets are built around children; JMBricklayer's sets are aimed at teens and adults, and its RC excavator is marked 14+.
