Moving forward is a good thing.
If memory serves, (If I am mistaken I guarantee I will be corrected) you should be able to run the command certbot without additional tags or configuration elements.
Certbot should give you a list of all of your domains (and it looks like you have quite a number) including bikegeartracker.com and www.bikegeartracker.com.
There should be an option to EXPAND the certificate with additional domains in your configuration. You can’t put more than 100 entries into a single cert but you can use multiple certs.
Hope this helps!
