Build and test three different motorized vehicles—a dragster, a bulldozer, and a dune buggy—then motorize your Lego® collection by customizing the vehicles with your own bricks. The Power Core has two different gears that provide high speeds, high power, and options for going forward and reverse. With MotorBlox, young engineers will learn about gears, torque, traction, vehicle design, and how to problem solve as they build. With MotorBlox the possibilities are endless!
