LEGO 1974 / Universal Building Set / Gears Sets

The LEGO Universal Building Set Gears theme, active from 1970 to 1974, introduced mechanical components to enhance the building experience. Key sets include 800 Gears, Motor and Bricks, which combined gears and a motor with standard bricks, allowing for the creation of moving models. The 801 Gear Set provided a variety of gears for constructing mechanical assemblies, and the 811-2 Gear Set offered additional gear elements for more complex designs.

1974 LEGO Sets

In 1974, LEGO released several new sets and themes, including the LEGO Universal Building Set, which included a range of new bricks in different shapes and colors. 1974 was also the year that LEGO introduced the LEGO Technic theme, which focused on building complex, mechanically-themed models such as cars, airplanes, and construction equipment. The Technic theme introduced new elements such as gears, levers, and motors, which allowed for more realistic, functional models. Other notable sets and themes released by LEGO in 1974 included the LEGO Space theme, which expanded upon the Space sets released in previous years, and the LEGO Trains theme, which introduced the first LEGO electric trains.
