LEGO TECHNIC 42225 Yellow motor Building blocks Multicolor

The LEGO TECHNIC 42225 Yellow engine is a compact and dynamic building set for children aged 7 and up. With 151 parts, your child can build a sporty yellow engine step by step. The working steering allows it to steer for real, while the engine with moving pistons comes to life as soon as the rear wheel turns. This mechanical effect makes the game extra engaging and provides immediate insight into how technology works. This way, your child combines building fun with discovery and builds self-confidence with every turn of the wheel.
