The Mattel Fisher Price Smart Cycle is a toy that is highly sought after by parents looking to engage their young children in exercise activities. This has become hard to find as it's been discontinued. I believe you must have the app to use it. App is not available anymore on the app store so you must have it already on your phone to use the item properly. If not it's still a great item for your child to use for great exercise and to mimic the parents if they are working on a stationary bike as well.
