LEGO Technic Yellow Motorbike 42225

A cool first motorbike build for young engineers

The LEGO Technic Yellow Motorbike (42225) is the perfect next step for kids who love motorbikes and are ready to move beyond LEGO City into the world of real engineering. With its bright yellow fairings, working steering and a moving 3-piston engine, this affordable set gives young builders a proper taste of how motorbikes work — all while keeping the build fun, achievable and action-packed.

Designed for kids aged 7 and over, this model introduces core Technic mechanics in a hands-on, easy-to-understand way. As they build, kids discover how the rear wheel turns the pistons, how the bike steers, and how different parts fit together to create a sturdy machine. It’s a confidence-boosting project that makes them feel like real engineers, and once the build is complete, the motorbike is ready for plenty of swooshing, racing and imaginative play.

With 151 pieces and a finished length of over 16 cm, the Yellow Motorbike is just the right size for small hands — big enough to feel exciting, but light enough for everyday play. Builders can also use the LEGO Builder app to zoom in on steps, rotate the model and track progress, giving them extra independence as they learn new skills.

Whether it’s a weekend project or a birthday surprise, this set is a brilliant introduction to the Technic range and an ideal starting point for kids who dream of engines, gears and fast bikes.
