Whenever you use VirZOOM Arcade, you sign into an account so the game knows which user is biking and can track their performance. Registering for My VirZOOM creates one account for you automatically. (And if you're the only one using the bike, you don't ever need to create another one!)
Every account has a unique name (which appears over players' avatars in multiplayer games), friends list, Pandora and Strava hookup, and leaderboard rankings. You can also enter a Bio on your account page to describe your available times and favorite VirZOOM games, which will show up in search results for anybody looking to add friends.
You can create additional accounts using My VirZOOM in case multiple people in your household want to track their VirZOOM progress separately. Every account requires email verification, but you may use the same email address to set up any number of accounts.
Please note that age, weight, and gender information requested for accounts is only used to provide better estimates for how many Calories you burn with VirZOOM. You don't need to enter anything in these fields if you prefer not to share this information.
