What is LEGO Technic?

The very first LEGOĀ® Technic sets in 1977 included forklift, tractor and crane toys for children looking for a more challenging LEGO building experience with a brand new range of LEGO elements. Since then we've created hundreds of sets with wonderfully complex mechanisms in hugely advanced models for both children and adults to enjoy. This journey has also led us to create a 1:1 scale sports car in recent years, in our ongoing mission to build for real!
