The product is too small.
According to the product information, the quad should be 26 cm by 16 cm. I put it together and it measures 16 by 10 cm. Something is clearly wrong here!!!

Retailer reviews
Summarized retailer review data when available.
According to the product information, the quad should be 26 cm by 16 cm. I put it together and it measures 16 by 10 cm. Something is clearly wrong here!!!
I just gave it to my grandson and I can't say anything about it. However, he was very excited when he received the gift.
The box art is quite cool, but the building process was fun, and I'm very satisfied with the finished product. I think it's a very good product that's worth buying.
I am very happy with Technic LEGO. It is very fun to build and you can also expand it. I hope that more new models will come in the future. I also have a lot of Technic LEGO myself. Best regards, Erik Miedena. P.S. I hope I can get 100 euros.
Fast delivery, well-packaged, and yes, LEGO is LEGO, which is great.
LEGO is always LEGO, a guarantee. This box was purchased to be used with the 42033 set, which can be used to build a nice truck. I find these LEGOs to be very well made and easy to assemble, even for younger children than those indicated on the box. This idea of LEGO creating instructions that allow you to combine two boxes to create something bigger/nicer is really great.
My nephew was very pleased with this. Chunky wheels, robust assembly and pull-back-and-go motor included. It also comes with this great facility that if you pair it with another (specific) Technic kit you can create a whole new monster vehicle - nice touch!
The Lego Technic series is very interesting because it introduces complex gears and mechanisms, which can then be expanded into projects with motors, sensors, and finally with Lego Mindstorms. This project allows you to build a quad with a screw motor (pulling the quad backwards, it gains momentum forward). It is a medium-complexity project that can be completed in one or two afternoons - depending on the child's age. My 6-year-old built it with my help (minimal, more companionship than help) and really enjoyed the project. He is very enthusiastic about these projects. Once the quad is built, it works very well, rolls smoothly, withstands impacts and turns, and the motor provides a good amount of power. It is a more solid and well-built toy than many other plastic vehicles he has had. Building these projects is excellent for learning because, among other things, it: - searches and identifies pieces - analyzes and understands - makes mistakes and corrects them - 3D complex diagrams - fine motor skills and coordination. If the child/child likes it, it is worth it.
Beautiful and technically advanced LEGO car. In addition to the fun of building, my eight-year-old son also plays with it endlessly in combination with his other vehicles. Really great toy!
My son thinks it's great. Compared to the other LEGO Technic cars, this one is a bit bigger. But overall, it's good. Also easy to assemble.
