FRS/GMRS for motorcycle travel comm.

Hi,
We are looking to add two radios to our bikes for talking while traveling on the highways. Short distances, several hundred feet to mile apart.
Would like to have radios that have standard USB charging to plug into our power ports on our bikes. Both Harley’s, 1 Ultra and 1 Street Glide. Yes I have CB, but hers doesn’t.
I’ve noted the Uniden 3040-2CKHS has a usb charging, are there any others?
Thanks in advance.

Jerry
