Conventional bikes can do just as much damage in an accident as an e-bike. It isn't the bike that causes these problems, it's the people who ride them.
Wish this were the whole story, but we can't ignore the fact that ebikes — even legal ones —
enable bad behavior in ways that unmotorized bikes do not.
Please understand that what I'm about to say comes from a throttle user, not a throttle hater.
1. Most of the bad actors wouldn't be on a bicycle at all if they didn't have a motor to do most or all of the work. They need motors and throttles, hand or foot, to wreak their havoc.
NB: Ghost-pedaling a simple cadence-sensing ebike — the most common kind here by far — is equivalent to using an all-or-nothing foot throttle. Here, I'm using "throttle" to refer to ghost-pedaling as well.
2. Most yahoos would never get close to 15 mph on the flat if they had to put out the necessary watts themselves. That's a common official speed limit on public bikeways. Still too fast in many situations, but way safer than 25+ mph.
3. The yahoos will always be with us. We just don't want them on anything that even looks like a bicycle.
The SoCal ebike dealer who sold me my first in 2022 thought
continous throttles would eventually be banned on new ebikes here. He thought a throttle that could only run for, say, 5-10 sec at a time would cover
most legitimate uses but not the yahoos' needs.
Interesting idea. A lot of future yahoos would lose all interest in ebikes.
Personally, I'd be OK with that. The thumb throttle on my clumsy 70 lb torque-sensing commuter is a non-optional knee preservation device. But I rarely need it more than 3 sec at a time, and don't need one on my 38 lb gravel ebike at all.
Problem is, we have many, many responsible utility riders here in hilly coastal SoCal, and they vastly outnumber the yahoos. Continuous throttles enable much of their riding as well.
Yes, I know that utility cycling is very popular outside the US, and those riders get by just fine without throttles. Different cycling history and culture.
Bottom line: Time-limited throttles would put a lot of cars back on the road in SoCal.
Honestly, I don't know what to do about the yahoos. It's a really tough problem, and the odds of a rational solution in the current media/political climate in the US are slim to none.
