China urges citizens to trade in 'old lithium e-bikes' for newer lead acid electric bikes

[venator@lemmy.nz]

Traded-in e-bikes will be sent for dismantling and recycling

Maybe they need the batteries for something else...

[bigdanishguy@sh.itjust.works]

No, they copy first movers.

the joked passed so far over the head of [email protected] that most observers thought it was an aeolian dust particle trapped in the outmost jetstream

[sugar_in_your_tea@sh.itjust.works]

Yeah, I'd totally buy a sodium ion battery. I think they have something like 75% the energy density per mass vs lithium ion, which is totally fine for my use case (commuter).

[lordwiggle@lemmy.world]

Just get rid of cars and fix proper biking and public transportation infrastructure. No need for that many cars, electric or not. Lithium is finite, the mines are horrible. But we're getting nuclear diamond batteries soon, they are a massive upgrade.

[raouldook@lemmy.world]

Sodium Ion batteries would be a better weight compromise than going to shitty old lead batteries. The new sodium batteries have almost no downsides but aren't quite as energy dense as lithium types. So they might be great in a large vehicle that's already going to be heavy, not so much in a smaller car. Saving the lithium stuff for smaller things is best (phones, laptops, etc)

[raouldook@lemmy.world]

Same in the US too. LiFEPO4 storage batteries are available cheaper than lead-acid for equal or even higher capacity.

Until the trumptard tariffs wreck our markets at least

Seems like cars don't all need 300 mi range, but a 5 lb weight difference in a bike is huge.

[gayhitler@lemmy.ml]

China has very developed bicycle infrastructure and massive public transportation compared to almost anywhere else. There are fewer car owners per capita than other countries. It’s still a smart play to use the hand of state to take steps to allocate the more energy dense batteries to applications that require them.

As I said before: Maybe these better chemistries that will replace lithium are just around the corner. I certainly don’t count unhatched chickens.

Five pounds is the grocery bag dangling off my flat bar.

[sem@lemmy.blahaj.zone]

Anyone who actually has done that knows that it always ends up swinging around and ending up in the spokes if you go fast enough.

Also 5 lbs is not a big deal when it's detachable, but it matters a lot more when it's part of a large 30+ lb object you're carrying up the stairs to your apartment.

[gayhitler@lemmy.ml]

Wait so would you leave your groceries outside while you carried in your bike?

[sem@lemmy.blahaj.zone]

Personally I use a backpack ever since the groceries in the spokes incident

[bilb@lem.monster]

The very next sentence specifically mentions that they did institute new safety standards

[gayhitler@lemmy.ml]

So you carry the groceries upstairs at the same time as your bike?

[sem@lemmy.blahaj.zone]

Have you heard of torque by happenchance?

[gayhitler@lemmy.ml]

How much does torque come into play when you’re carrying your bike upstairs?

[sem@lemmy.blahaj.zone]

The part where lifting a mass on a long lever is not easier than carrying it close to your body

[gayhitler@lemmy.ml]

Yeah when I had to take my bike upstairs I would just hoist it over my shoulder then hold the grocery bags in the same hand so it’s close.

Weve gotten far afield and I’m genuinely thinking you made that comment thinking a person might leave their Walmart bag hanging off their handlebars while carrying the bike in…

What are you talking about?

[sem@lemmy.blahaj.zone]

I'm talking about how a heavy bike is worse than a car with less than 300 mi range, relatively speaking.

[gayhitler@lemmy.ml]

Okay but you’re not lifting the bike by its chainstay and swinging it around like a claymore or something, you lift at the center of mass, which in an e-bike is at the battery or damn close to it. It’s why they’re all in the triangle or under the rear rack and in the latter case manufacturers get away with it because you put the bike over your shoulder and use your hand on the bars to stabilize it thereby reducing the impact the battery weight makes on the bikes portageability through the use of the same lever whose fulcrum is your shoulder.

A lot of what you’re saying seems to me to be dancing around the point of “I want an incredibly light, fast e-bike, not a 50lb grocery getter”, and I truly understand that desire. But the reality of the e-bike buying public is that people want those 50lb grocery getters.

It’s the same as the car market. I want a manual everything, decently high displacement inline four with a manual transmission, manual 4wd, crawler gear and enough ground clearance that dirt roads aren’t an issue. Everyone else wants maximum fuel economy and lots of features so all the cars accommodate that set of desires instead of mine.
