Most of my issues come from people riding the latter of those two categories, however some of the concerns directly relate to both.
E-Bikes have a huge part of their ownership caught up into two groups that are doing the entire sector harm as well, the first group causing harm is those who are out modifying these bikes and getting them up to highway speeds in some cases, the second group are people who are turned to these as a mode of transport because they have lost their licenses due to DUIs and now take those same impairments to the E-Bike world.
Several crucial problems exacerbate the situation: the absence of mandatory safety equipment such as helmets, the lack of insurance coverage, insufficient training provisions, and the absence of mechanisms for accountability and identification of riders and their respective bikes.
In my personal opinion, a comprehensive solution for my region involves licensing all E-Bikes under the moped or limited-speed motorcycle license, requiring license plates, and implementing cost-effective insurance options (possibly achieved through government subsidization).
