The bike, aimed at 3 to 6 year olds, lets kids interact with gaming apps while pedaling. The Smart Cycle comes with one free app and works with four others, including SpongeBob SquarePants and Shimmer and Shine apps. The included app features an age-appropriate curriculum based on math, science and social studies. "They're learning and mastering content as they pedal, fast or slow, forwards or backwards," Amber Pietrobono, a spokeswoman with Fisher-Price, told CNNMoney. "It's also how they level up in the games."
