This set is so awesome, so many parts and cool pieces. If you like technics you are going to love this set. I will admit it will most likely not stay together as the excavator. We will probably tear this apart to make other cool technic builds. One caution this has a lot of gears and I mean a lot. When assembling it is very important to make sure the gear box assemblies move freely. If you build with to much friction it will not function properly. Should also note that when picking up the rock pieces they tend to bounce around and fall off the conveyor belts at the transfer points. They fall down into the gearing and stop it from functioning. This usually is not a problem for older kids, but my 5 year old seems to have a problem with bricks falling all over into the lower gearing. It crawls, it swivels left and right, and the Excavator raises and lowers. Took us 5 days to build (2-4 hr each day). It has a cool dump truck that is a fun build as well.

Each step of the building process includes a short list of pieces that are required during this particular step, and my fault was not being attentive enough. On the other hand, I would say that massive sets like this one lack check points that will help you try all the mechanisms as they are being assembled. Being able to find a mistake as early as you made it would save a lot of time, but discovering one small mistake 3,000 pieces later is a little bit heartbreaking.

Lego (Danish: [ˈleːɡo];[1][2] stylised as LEGO) is a line of plastic construction toys that are manufactured by The Lego Group, a privately held company based in Billund, Denmark. The company's flagship product, Lego, consists of colourful interlocking plastic bricks accompanying an array of gears, figurines called minifigures, and various other parts. Lego pieces can be assembled and connected in many ways to construct objects including vehicles, buildings, and working robots. Anything constructed can then be taken apart again, and the pieces used to make other objects.[3][4]
This kit, another great one for younger kids, is very lightweight and easy to carry - encouraging imaginative play with the completed model. It is very budget friendly too and is one of the cheapest LEGO Technic kits on the market. The twin-rotor helicopter measures around 4 inches high, 9 inches long and 7 inches wide when fully built. To play with it, kids simply follow the simple instructions which, according to reviews, will take most young kids a day or two.
This is of course compatible with all LEGO construction toy sets and is therefore a good additional gift for kids who already own and love their LEGO sets. There are no electrical components so no need for batteries - kids simply pull the car back and release to drive it. The tires are designed for racing, so this Lego Technic racing car is great for playing with other LEGO Technic vehicles.

Technic has certainly produced a lot of large models this year. Only 5 out of the 12 sets this year are under $50. These three are the best of them all, in my opinion. The accuracy of detail in the Volvo EW160E and the CLAAS XERION, combined with their functions, make them truly great sets. Now, the BWE is indeed the largest Technic set ever by piece (it’s 7th largest overall) and probably size, and it’s my favorite of the three. Its poor performance, however, lets the model down somewhat. I think it needs 2 XL-motors, not one, for power. The Mobile Aggregate Processor works okay, though, and it looks quite cool. Sadly I will have to pass on it, in favor of many other sets this year. 🙁
Hi, just wanted to say thank you for your site....I was feeling a little nostalgic, browsing the internet checking Lego Technic sites and came upon yours.  The best Lego site I've ever encountered.  It brought back many many memories of sets I both owned and had wanted in the past.  Thanks for all your hard work, wonderful pictures, videos, and your great comments.  Keep it up!
Early TECHNIC motors used the standard 4.5V system, interchangeable with the Trains theme and consisted of a large brick with a small protruding axle. When the motor is activated, the axle rotates. From 1990 onward, this was changed to the 9V system in line with other LEGO themes. The output rotation has a high RPM, but low torque, so it cannot be used to turn heavy objects without additional gears. Later motors contained a hole into which an axle of any length can be inserted.
➡ #42054 LEGO TECHNIC CLAAS XERION 5000 TRAC VC: What really stands out with this vehicle is the color-scheme; the lime-green, red, and white combination really pops and makes this an impressive display-piece. But there is more. The model is also motorized the raise and turn the cab and to operate the crane, and there are a number of hand-operated features as well. Unfortunately the model can’t pick up any heavier weight (not even a banana), as you can see in the video-review below, and the alternate model is just a rebuild of the attachment, but it is still a very cool looking set.
Well, there is the #45517 Transformer 10V DC that LEGO sells to go with the #8878 Rechargeable Battery, but then you would have to use 8878 instead of a normal battery box, and it is a different size that wouldn’t easily fit in the BWE. However, the problem remains, as I doubt you can both charge and use 8878 at the same time. So, no, I don’t think it’s possible to connect the set to an electrical socket and constantly power it that way. And re-engineering sounds risky… the motor might get destroyed. 😕
We spent 25 hours on research, videography, and editing, to review the top selections for this wiki. Those who enjoy constructing replica vehicles will appreciate this list of Lego Technic Sets. These toys are not your typical building blocks; they require careful attention to detail and lots of time to assemble, which is all part of the fun. Here, you'll find luxury cars, off-road bikes, trucks, and much more to add to your collection of true-to-life models. When users buy our independently chosen editorial picks, we may earn commissions to support our work. Skip to the best lego technic set on Amazon.
My son bought this to go with the Lego fairground creator set. He successfully put the motor in the set to power the ride. The plus side is Lego quality. My gripes include the need for six batteries (whoa) and the fact that the battery case is not really Lego friendly - specifically it offers limited options for snapping the case onto a Lego base (I guess it's because it's a technic thing).
Manufacturing of Lego bricks occurs at several locations around the world. Moulding is done in Billund, Denmark; Nyíregyháza, Hungary; Monterrey, Mexico and most recently in Jiaxing, China. Brick decorations and packaging are done at plants in Denmark, Hungary, Mexico and Kladno in the Czech Republic. The Lego Group estimates that in five decades it has produced 400 billion Lego blocks.[41] Annual production of Lego bricks averages approximately 36 billion, or about 1140 elements per second. According to an article in BusinessWeek in 2006, Lego could be considered the world's No. 1 tire manufacturer; the factory produces about 306 million small rubber tires a year.[42] The claim was reiterated in 2012.[43]
Actually, I love the purpose of stickers in this set. They do not influence the shape of the crane, but rather fill empty spaces and emphasise things that need your attention. For instance, a whole bunch of pinch point labels are placed by the exposed gears on top of the tower. Hiding gears inside the body would cost space and panels, and stickers help to solve this problem in a very elegant way.
Since around 2000, the Lego Group has been promoting "Lego Serious Play", a form of business consultancy fostering creative thinking, in which team members build metaphors of their organizational identities and experiences using Lego bricks. Participants work through imaginary scenarios using visual three-dimensional Lego constructions, imaginatively exploring possibilities in a serious form of play.[73]
Stafford considers the Galidor line to be Lego's most heinous offense. Based on a kid's show of the same name, the line was basically an action figure series with awkward features like interchangeable arms for characters. Each set in the line featured specialized pieces, which were expensive to produce and in practically no way resembled a Lego product.
There are several robotics competitions which use the Lego robotics sets. The earliest is Botball, a national U.S. middle- and high-school competition stemming from the MIT 6.270 Lego robotics tournament. Other Lego robotics competitions include Junior FIRST LEGO League (Jr.FLL) for students ages 6–9 and FIRST Lego League (FLL) for students ages 9–16 (age 9–14 in the United States, Canada, and Mexico). Jr.FLL and FLL offer real-world engineering challenges to participants. FLL uses Lego-based robots to complete tasks. Jr.FLL participants build models out of Lego elements. In its 2010 season, there were 16,070 FLL teams in over 55 countries. In its 2010 season, there were 2,147 Jr.FLL teams with 12,882 total student participants in the United States and Canada. The international RoboCup Junior football competition involves extensive use of Lego Mindstorms equipment which is often pushed to its extreme limits.[53]
