Certainly 100% the cyclist fault.
If it was a cyclist/pedestrian on the road hit by a car, it would be the car's fault.
E-Bikes are motorized vehicles IMO, should be licensed and treated as such. Manufacturer's are just using a pedal loophole to get around the laws.
Bike/hiking paths usually state non-motorized trails, E-Bike's have a motor and should not be allowed.
I get a pretty good laugh when walking/hiking on these paths and all of these "bikes" go by. Amazingly the riders are not even pedaling.
Main problem I have with cyclist is they seem to want the best of both worlds.
