There is an inverse relationship between how fast someone can pedal, and the likelihood of injury. If the society picks up the bill for injuries people cause to themselves, then it is perfectly reasonable to regulate to some degree things that are commonly used and that can easily cause injury.

If you unplug the battery from the charger and before you plug it into the bike, does it have voltage on the output?

Maybe these are standby batteries out of stolen EV vehicles? The batteries were cut out to shut off all tracking and beacons in the vehicles, then they were put in crates and shipped overseas? That's my best guess. :mrgreen:

Why not turn them and measure?

I doubt there is anyone in the whole world who repairs these. Even if it didn't have that protective varnish on it.

Some early belt designs sucked. But that's 25-30 year old news. Toyotas have always used planetary gear CVT designs in their hybrids, which is the most reliable transmission ever made judging by the fact that you won't find any complaints about them, and the number of used Toyota hybrids with...

That's my assumption if we are talking e-bike battery.

You need less than 1mm to prevent 100V DC from arching. There is absolutely no chance no way not under any condition less than 1mm gap inside that switch when it's off.

Threaded flange coupling bolted to a sprocket?

You do realize that vehicle depreciation is the single best predictor of reliability and future cost to own? 🤔

More airbags? Soundproofing? Adjustable seats? Staying on the road at over 35mph? Not failing every crash test? Pretty much everything a modern car would offer. :ROFLMAO: That looks like a vehicle that would be good for groundskeepers at a corporate complex or a university campus, driving...

I don't think you looked at modern offerings recently. For $35K you can get a loaded Camry that's slightly bigger, slightly safer and gets over 50mpg both city and highway. With various fees states are putting on electric vehicles, to offset the owners not paying any gasoline taxes, I doubt a...

1% of total vehicles being EV is mass use? I don't think so. We are still about 2 decades away from any reasonable definition of mass use. As such, nobody can do any kind of research compile statistics since there is no representative sample available. Comparing statistics about new electric...

There is quite a difference between a lead-acid battery which is basically a chunk of lead in a thin plastic shell, and a car battery which is an armored solid block of a dozens of different metals, plastics and epoxies fused together.

Today is year 2023, almost 2024, and the vast majority of our "recyclables" ends up in landfills, even though great energy is expended to sort and transport it separately. All projections from the past about recycling in the future have fallen flat.
