The LEGO Technic All-Terrain Vehicle (42139) is the perfect building toy for inquisitive kids who are aged 10 and up. With realistic features, such as a steering and suspension, gearbox, and engine with moving pistons, this ATV is just like a real one. The cargo bed even tips, ready for lifting and transporting heavy loads. This construction set also comes with a toy chainsaw and 20 small log elements that can join together to make larger logs. Kids will love using the chainsaw to ‘chop’ the logs and engage in creative play with the realistic details. This is a great introduction to engineering with realistic movement and mechanisms that introduce young LEGO builders to the universe of great vehicles in a realistic way. With 764 pieces, this is a rewarding building project and the model measures over 4 inches high, 10.5 inches long, and 5 inches wide. This LEGO Technic set makes for a fantastic gift idea for kids who love functioning models, and you can be sure that it is of the highest quality, having met rigorous industry standards for safety and compatibility.
