Just checked the bike index site.
The serial number I have is not in their listings.
Thanks for advice.
Everything I checked is legitimate.

I have sent them a request for information. Got an automated answer because of covid and the season. They stated they are very busy but would get to my request for information. Thanks for info.

I just purchased a Radcity bike without battery and charger. I want to purchase a battery and charger but no sure what battery to buy.
What information is included in the serial number on the bike. Also best place to but a battery.

Thanks for help
