It defines what an LSEB is... for sale yes, but the definition is key. Comply with those requirements and your LSEB can ride anywhere bicycles are allowed. That's "Bright" enough for anyone to see and read and need no more light shined on it. The 3 class system is being adopted by more and more states and will eventually be a standard. The problem arises when the majority of rides want a Class-3 ebike (baby electric motorcycle) rather than an LSEB. Since money is the only thing people care about anymore once it's shown that ebike use stimulates the economy there will be no issues. I ride in National Parks and Forests almost weekly and have never had a problem if signage is posted No Bicycles... I don't ride there, but I ride around No Motor Vehicle Allowed signs all the time. You all have the keys to the castle so to speak but don't seems to use them much. Ride safe.
