| LEGO® Technic 4x4 X-Treme Off-Roader (42099) Take on any terrain with this seriously capable remote-controlled off-roader built from 958 pieces. Designed for builders aged 11 and up, this rugged beast is packed with real working functions that go way beyond just looking good on a shelf. Power comes from an electric motor connected to the Powered Up app, letting you control steering, speed, and direction straight from your smartphone or tablet. The functional steering responds with satisfying precision, while the 4x4 drivetrain means this thing actually handles rough surfaces the way a proper off-roader should. The chunky suspension soaks up bumps, the aggressive bodywork looks the part, and every mechanical detail rewards the time you put into the build. This is the kind of set where the construction process teaches you something real about how motors, axles, and drivetrain components work together. Compatible with the free Powered Up app for full remote control capability. Requires a smart device and batteries.
