You could also get one of the SSD drives that look like flash storage. I got a “usb stick” with 512GB SSD for about $60 last year.

No idea about bike licenses.

High power radios in the hands of people who don’t know what they’re doing can cause a lot of issues. FRS/GMRS radios under 2 Watts in the U.S. don’t need a license. Licensing is a way to make sure people using them know how to do so effectively, and provides for stiffer penalties if someone unlicensed causes issues.
