The Inventor Motorized 4-wheeled Extreme Bike with 10 bonus models offers a thematic approach with multiple model capabilities, featuring an impressive main model. A new library of components with pending patents has been added to the ENGINO® system, enhancing both aesthetic and technical characteristics. These components include high-precision wheels, mechanisms, and curved surfaces with a snap-fit system. The smaller sets in the range are suitable for children aged 7 years, while the larger sets are intended for older children, also including a gear mechanism. The top grades increase complexity with Robotics technology, Bluetooth connectivity, and software control.
