Description

Gear trains you turn yourself

Unlike its motorised sibling, this set relies on hand power. You turn a crank and watch the motion travel on through several gears. It is a wonderfully calm way into mechanics: you feel the resistance and notice how the force changes as you move from a large wheel to a small one. For children and adults alike it is a vivid lesson, and it needs no electricity whatsoever to work. Changes are felt at once, which is why the learning effect stays strong.

The parts in detail

With 113 pieces in 32 different shapes, the selection is wider than you would expect from such a small set. Gears of various sizes, axles, beams and connectors form the basis. Because almost everything can be combined freely, there is no single fixed model, more of a toolbox. This page shows the complete parts list with quantities. That helps when you are checking a second-hand set for completeness, because a gear or two often goes missing.

Red, light grey, yellow and black

The palette matches that of the sibling set with a motor: red, light grey, yellow and black. This means the two sets combine without any trouble if you own both. The colours have a practical use as well, since wheels in different colours are easier to tell apart in a running gear train. You see at once which wheel drives and which is driven, and can adjust or extend your construction accordingly. That also saves time when you rebuild.

Building on and combining

There are no minifigures; the appeal lies in the construction itself. Owners can build things like a hand-cranked machine, a simple carousel or a windmill from it. Use the “What can I build?” tool to see which models your collection and these gears could make together. Pairing the set with a motorised one opens up many further possibilities, since the elements are designed to work side by side. That flexibility is the real strength of the set.
