The Oregon Senate passed a bill updating laws around electric bicycles on Monday. It's named for a Bend teen killed in a collision while riding an e-bike last summer.
I did way more than 1000km/month on my bicycle back in my time. I know what happens when you are stupid enough to break with the front wheels only. Even with disk brakes on both wheels you don’t have enough contact with the ground to ride at such speeds in a traffic-safe way. That’s why I object to the idea that a bike with 28mph would be safe, and would definitely require insurance for such a vehicle.
The brake reaction time normally used in design, therefore, is 2.5 seconds.
Stopping distance in a car is therefore 140.22 ft.
Do you think that you can’t do equal or better on a bike?
Any situation that you believe a car can do safely, there’s no reason to believe a bike couldn’t either. FFS we have these wonderful things called motorcycles. Much less contact with the ground [than a car], much higher speeds. Works just fine.
