This is a LEGO All-Terrain Vehicle 42139 764-piece brick set that has elements similar to those found on a genuine ATV. Examine the steering and suspension before moving on to the gearbox and engine, which has moving pistons. There's a winch and a tipping cargo bed, so you can lift and carry huge objects. This ATV model comes with a toy chainsaw that rotates like a real chainsaw. Kids will enjoy 'chopping' the log accessory pieces with their chainsaw. The 20 little log parts combine to form giant logs, making it ideal for both children and adults to engage in creative play. LEGO Technic building kits include realistic movement and mechanics that expose young LEGO builders to the world of engineering in a fun and engaging way. Show off your engineering skills by building the LEGO All-Terrain Vehicle 42139 set. Customize this ATV with our ever-glowing LEGO LED Lights to make it come alive.
