LEGO Technic

Introduced in 1977, LEGO Technic is a line of complex LEGO parts. The purpose of Technic is to create advanced models with complex technical functions, compared to the simpler brick-building properties of “classic” LEGO. Over the years, LEGO Technic has evolved from studded to studless designs (bricks without the iconic LEGO studs on top), which enable building of even more complex models.

BUILD exciting models

LEGO Technic models are getting bigger and bigger, built with more parts. That is why they are so interesting. With LEGO, bigger is better.

Spend quality time with your children and build something together. Or buy a set for yourself and re-discover your inner child 🙂

Why LEGO Technic fans love BuWizz?




The unique feature of the BuWizz is as "Fast" mode, which provides a voltage that is higher than any LEGO-battery-based solution. It makes a noticeable difference in motor's performance.


Prolific LEGO Technic builder

The interface is simple and easy to understand and to connect. The default profiles are easy to use and the Buwizz responds very good to action on the phone. Plus a fast mode for the motor which enable 11V on it (no damage for the motor).

Therefore, I really encourage you to buy one, this is way better than sbrick. Despite the price, you have the equivalent of a working sbrick with a lipo battery which can be charger by a simple usb type B. So not too much money comparing to lego PFS solutions.

In principle this means Anto’s Citroen could drift, if only LEGO motors had a bit more power…

With the addition of a third-party BuWizz bluetooth battery brick however, they do. A lot more. The BuWizz system delivers up to eight times more power than normal to the LEGO motors, and that is easily enough to spin the rear wheels on a not just a hardwood floor, but pretty much anything.

The Lego car Blog

The BuWizz is smaller and lighter than the Battery Box and delivers more power for longer. Perhaps the best feature is that the BuWizz has a high-power mode that delivers twice the power to the motors, enabling the motors to handle high loads from large builds or driving outdoors. Finally, you can drive your Lego vehicles on the grass or up slight inclines without having to worry if the motors can take it.
