Many of us approach cycling from a sporting angle. From this perspective, a motor is almost obscene.
From a transportation angle, it makes more sense. E-bikes are meant to replace cars, not bicycles.
I also think they should remain on roads, and not on cycling / ped /hiker/ horse infrastructure. Motorists have a different mentality that is not compatible with non-motorized traffic.
As more people ride, there will be more "bad" cyclists. Look at how bad people drive. Turning from the middle lane, taking up two lanes, driving slow in the left lane. Its not e-bikes. So many people don't care / don't know about traffic rules in general
I would welcome an ebike if it meant spending a day in the saddle with my wife (for her.) Riding with my wife is not sport either, but time with the wife. Ebike for sport? Not for me
