STEM LAB- Gearbox

The GEARBOX model kit is a miniature of a car transmission mechanism that transfers torque from the engine's crankshaft to the wheels. This mechanical toy features one reverse gear and three forward gears meaning layshaft and gears rotate with increasing speed. Like other UGears construction kits for adults and children, this educational toy has an iconic design and it moves.



The UGears STEM LAB helps educate kids while they’re having fun. Our building toys unveil the basic concepts of science, technology, engineering, and maths, and help children relate to things in the real world. The hands-on experience of putting things together is much more fun and made easier because each machine is fully explained. Try and assemble UGears science kits for children and adults either by yourself or in pleasant company.
