🎯 UGears STEM LAB Gearbox

Discover the mechanics of manual transmission with the UGears STEM LAB Gearbox model. This kit builds a fully functioning interactive puzzle that helps you study the gearbox, the groundbreaking invention of German engineer Karl Benz widely used in cars today. A mechanical gearbox transfers torque from the engines shaft to the wheels. When assembled, this model will help you learn how a 4-speed manual transmission works by providing a hands-on experience of the physics involved. Choose a speed with the mini gearshift lever, then turn the actuator handle to spin the gears. Shift into reverse to see how the clutch transfers the rotation to the lower gears, which propels them in the opposite direction. we ship fast 🚀
