I have mixed feelings about e-bikes. On one hand I often see some on the way to work and I think they are the perfect commuting vehicle when the commute is just out of range for a regular bike.
On the other hand I have seem problems on the local recreational bike path (W&OD) ranging from mildly annoying (a family on e-bikes on a path clearly marked “No motorized vehicles” to obnoxious, (a fully enclosed electric cart that takes up 3/4 of the path). That dam thing is a mini electric car! I’m not sure what kind of entitled a-hole thinks it is ok to take it out there on crowded days.
