Description * 2-in-1 Fun: A Four-Wheel Bike and a Golf Cart in One Book! Using a toy driver and wrench, kids can turn and tighten 60 small and large parts to build a four-wheel bike — and then use the same parts to build a golf cart! This 2-in-1 building set helps children develop focus as they carefully assemble each piece, while also boosting creativity as they try building their own unique designs. * Learn About Four-Wheel Bikes Through the Picture Book While camping by a river, sudden rain floods the road — and that's when the four-wheel bike shows off its special skills! With its sturdy wheels, it can easily handle bumpy or steep paths. As children read the story, they'll naturally learn about the four-wheel bike's unique features, which combine the best qualities of a motorcycle and a car. * Enjoy Imaginative Role Play with Your Own Vehicle Pretend to be a four-wheel bike riding over bumpy rocky roads and steep hills, or become a golf cart carrying equipment to where it's needed. Kids can even try designing a brand-new vehicle of their own! Role-playing with their handmade car helps build curiosity and imagination. * Easy to Build with Video Instructions The Brave Four-Wheel Bike picture book includes instructions for building both the four-wheel bike and the golf cart.
