For anyone that isn’t aware, a Sur Ron X is essentially an electric dirt bike that can get up to 50 MPH when modified.
Regarding safety, when it is a bike vs a car, I agree that having more speed is better and safer for the cyclist.
But the issue is when we have a bike vs a pedestrian. I've been a pedestrian next to groups of fast moving e-bikes. It can be pretty scary. Some cyclists can feel entitled to riding on the sidewalk, which at high speeds can really injure someone if they were to crash. E-bikes also weigh a lot more than a non-ebike (up to 120lb in some cases) so getting hit at top speed is a bigger deal than a normal bike.
My overall point is that I think cyclists need to start behaving more like vehicles, rather than fast-moving pedestrians. Obviously we need more investment in biking infrastructure for that to happen, but with how fun and useful e-bikes are, I am optimistic that will eventually happen. As e-bikes become more common, I expect this to become a bigger part of the conversation.
I agree, but there needs to be enforcement of laws against cyclists and e-bikers. The entitlement of sidewalk riding and red light running, in pedestrian cities that already have bike lanes like NYC, needs to be counterbalanced with fear of consequences.
