Ideia de tatuagem no estilo Neo-Tradicional "Design a minimalist wrist tattoo for a parent honoring their son Rafael. The tattoo should feature a blue and black kid's balance bike, exactly like the Buba brand bike shown in the uploaded image. The bike should have wide black wheels, a blue frame, black seat and handlebars, and the 'Buba' logo clearly visible on the frame. The letter 'R' should be subtly incorporated into the bike’s design, either as part of the frame or another key element. The tattoo should be clean, simple, and fit within a 3-inch diameter, using fine lines and clear details."
