Hello @CRM 

Thanks for posting about this.  It's a common issue and is almost always caused because you've created two peloton accounts - which is causing the error.  This is easy to do, especially if you've previously signed into Peloton at a gym or hotel.
 
You will need to find your original Peloton username and account to deauthorize the connection. 
 
Log back into that Peloton account on your bike and deauthorize Strava.

Logout, then back into the account you wish to connect to Strava and repeat the same connection process.
 
I hope this helps. Please let me know if you have any questions.

Is there any easy way to figure out what the email or username is for this second account?  I can’t find that information from Strava or my primary Peleton account. 

Hello @Joeustis96 

There isn't really an easy way to locate this information, but Peloton Support is the best place to start:

https://support.onepeloton.com/

I would recommend providing them with any other email addresses that could have been used to set up your duplicate Peloton account.  Also if you give them your Strava Athlete ID, they may be able to find the connection in their system and see what Peloton account is connected.
