The verdict

If your mate loves classic hands-on Technic with mechanical functions instead of an app, this is an easy recommend.

You get a genuinely good FMX tractor unit, a flatbed trailer, and a pneumatic excavator that combine into one 68cm rig. Just warn them the excavator is the weaker half of the box, so if they treat the truck as the star they will be very happy.

Best for: Technic fans who want functions and pneumatics over motors and stickers

The full review

What it is

Here is the pitch: one box, two vehicles, and a trailer to haul one on the back of the other. The Volvo FMX Truck & EC230 Electric Excavator is a 2,274-piece LEGO® set from the 2024 Technic lineup, and it is aimed squarely at the fan who misses functions you operate with your own hands instead of a phone. No motor, no batteries, no stickers doing the heavy lifting. Just gears, linkages and real pneumatics. When it is all done you have got a roughly 68cm articulated rig that looks the business on a shelf, and Brickset went as far as calling it near-perfect for both traditionalists and newcomers. That is high praise for a set that leans this hard into old-school mechanical play.

The catch

Now the honest bit, because your mate deserves it. The two halves of this set are not equal. The FMX tractor unit is lovely and does everything a Technic truck should. The excavator is where the corners got trimmed. There is no third pneumatic cylinder, so the bucket cannot tilt independently and instead swings in sync with the arm. The tracks have no rubber treads or traction parts, so the whole thing slides around on a smooth table rather than crawling. Reviewers keep landing on the same note: it looks great from a step back, but up close it promises a bit more than it delivers. Add a fiddly fifth-wheel coupling and no proper lock to hold the excavator on the trailer, and you have got a few small frustrations baked in. At around 200 dollars or 170 pounds it is fair value for the piece count, just not flawless.

Who it's for

So who should grab it? Anyone who wants a chunky, satisfying build with genuine working functions and a display model at the end, especially fans nostalgic for the pneumatic Technic sets of years past. It is also a great shared project since it splits neatly into a truck, a trailer and a digger, so two people can build side by side. Who should skip it? If your mate is chasing a powered, motorized excavator that crawls around the floor, this is not that, and they will clock the excavator's shortcuts fast. But if they go in wanting a hand-operated Technic centerpiece and treat the truck as the main event, this one gives back plenty of fun for the money.

The parts story

What the build is actually like, and the pieces worth knowing about.

The build splits into four clear chunks: the FMX tractor unit, the flatbed trailer, the EC230 excavator, and a little battery unit that props up the charging fantasy. The truck is the best part of the sit-down, with a fake inline-six that pumps as you roll it, hand-of-god steering, and a tilting cab that pops forward to show the engine. The trailer stage is quicker and more repetitive but gives you fold-down loading ramps. The excavator section is where the pneumatics come in: you assemble a pump, two control levers and two cylinders that drive the arm through a decent range of motion, all plumbed with airline tubing that tucks into the rear bodywork. Pacing is steady rather than surprising, and that pneumatic plumbing at the end is the most satisfying stretch of the whole box.

This is not a set chasing rare-parts glory, so keep the parts-nerd expectations sensible. The stars are the pneumatic components, the pump, cylinders and tubing, which are always handy to have in bulk and get reused across your own MOCs. You get a big helping of Volvo's signature yellow panels and beams, useful if you build construction models, some orange accent parts for the safety rails, plus the usual Technic connectors, gears and axles in generous quantities. At 2,274 pieces for roughly 200 dollars, the per-piece value sits right in the normal Technic band, and it is the pneumatic gear plus two complete models that make the pile feel worth it rather than any single show-stopping new mold.

Fun facts

01The real Volvo EC230 Electric is a 23-ton machine and was billed as the largest electric excavator on the U.S. market when it launched.
02The actual EC230 runs on Volvo Penta lithium-ion battery packs, which is exactly why this set builds in a pretend battery-swap and charging routine instead of a diesel tank.
03There is not a single motor or electronic part in the box, so every bit of arm movement comes from a real LEGO pneumatic system of a pump, two controls and two cylinders.
04Fully combined, the truck, trailer and excavator stretch to around 68cm long, making it one of the more shelf-hungry Technic sets of 2024.
