The UGears® STEM LAB Gearbox is an educational model and interactive study guide for learning how a car’s mechanical gearbox works as a reducer to provide speed and torque conversions from a motor to the driving wheels. After assembly, you can experiment with the manual UGears® Gearbox by turns. Choose I, II, III, or reverse, and using a kinematic pair of gears with different ratios and rotating the actuator handle clockwise, you can watch and control the rotation speed of the Layshaft and Drive Shaft. In a Position “N” – idle both clutch gears of the Layshaft remain uncoupled and idling. First Gear makes the Layshaft and gears rotate with the lowest speed. Second Gear lets the Drive Shaft, along with the flywheel, rotate with an average speed. Third Gear allows the Layshaft and all gears to rotate with the highest speed. Switch on the Reverse Gear and see how the Driving Clutch Gear moves to the left towards gear “R” and connects to it, transferring the rotation to the Lower Gear arrangement and propelling the Layshaft and all gears to rotate in reverse.

Needs modification to work correctly.

It is okay, but the brushes fall through the holes' making them hard to retrieve. The only way to get them out of the holder is to pull up on the bristles or push the handle from the bottom. Both don't work well. My solution is simple, just install a "stop" below the holes. My solution is ugly but works. It took me about 15 minutes to modify.
