Kids aged 6+ can learn as they play and explore their passion for engineering with detailed LEGO® Technic designs. Featuring functioning gearboxes, wheels and axles that kids put together themselves, each build will help grow children's understanding of the intricate details that propel the cars, planes, motorbikes and construction vehicles and make them work. Sets can be enhanced further with CONTROL+, a free app that can interact with many motorised LEGO® Technic remote control toys to add elements like movement and sound. These toys for girls and boys provide challenges and allow kids to share them with their friends. It's also a perfect gift for advanced adult builders.
