Please clarify? Are you talking about the Texas Laws? If you are you have to look up the laws on electric bikes and thats the path you have to go through, they are included with highway laws as well...
Yes this has been discussed in great detail. Laws are intended to prevent e-bikes from needing license/insurance/registration to be operated on maintained surfaces. They are not aimed at mountain biking.
FWIW, I fully support allowing e-bikes of the various types on maintained lanes/bike paths/etc.
