A man who narrowly survived an ebike battery fire that killed his partner and two children says he is tormented by grief and guilt but determined to fight to change the law to avoid similar tragedies.

Scott Peden, 31, was placed in an induced coma for a month after suffering 15% internal burns when he tried to wrestle his burning ebike out of his Cambridge flat last June. He also smashed his heel in three places jumping from his bedroom after the battery exploded.

When he was pushed back by the flames and toxic fumes he called to his partner, Gemma, 31, and children, Lilly, eight, and Oliver, four, to jump from the same bedroom. “She said: ‘I can’t get out.’ That’s the last words I heard. I don’t know what happened,” Peden said.

He added: “Gemma knew I tried to help, but did the kids? Was their last thought ‘where’s Dad?’ I feel so much guilt and fear about what they went through in those last couple of minutes, it hits me every day.”

Peden learned of their fate only when he emerged from the coma in a burns unit in Broomfield hospital in Chelmsford. He says: “They told me Oliver was found in his bedroom. Gemma was found in our bedroom doorway and Lilly was under our beds with the two dogs.” The fire destroyed the family’s council flat and everything in it.

Cambridgeshire police told Peden that his family and the dogs all died from lithium gas poisoning. An inquest into their deaths will take place after police have concluded an investigation. It has so far focused on the previous owners of a secondhand battery that Peden bought online days before it exploded in his hallway.

Gemma, Oliver and Lilly were among 11 people killed in fires caused by ebike batteries in the UK last year, believed to be the highest number in a single year. Coroners, fire officers and campaigners have expressed growing alarm about rising sales of unregulated and potentially lethal batteries.

The number of fires from ebikes and escooters in London more than doubled in two years, from 78 in 2021 to 179 last year, according to figures from the London fire brigade. In the first five months of this year there have already been 66 such fires in the capital.

Peden is backing a campaign by the charity Electrical Safety First (ESF) for a law change to ensure there is independent third-party certification in the sale of such batteries, as there is with other dangerous products such as fireworks.

Speaking from the Cambridge flat where he has been rehoused, Peden said he was an “unlikely poster boy” for the campaign as he was dealing with his own trauma. He said: “I used to dream the whole experience over and over again. The PTSD means that sudden bangs put me in a panic attack.”

But, he added: “Campaigning has given me a sense of purpose. My life has been ruined but I can help save someone else’s.”

At the time of the fire, Peden was working for M&S unloading early-morning delivery trucks. He shared the ebike with a colleague who worked the evening shift. When the battery was stolen he could not afford the £600 it cost for a new one.

After having struggled financially, the family was looking forward to Oliver starting school as Gemma could get a part-time job. He said: “Our lives were just beginning. We were looking forward to finally taking the kids on holiday. And it all got snuffed out in a night.”

Peden has not spoken to Gemma’s family since the funeral and says they are unlikely ever to forgive him. Asked what he would say to them, he said: “I’m sorry, that’s all I can say. Should I have just used a push bike? It’s all my decisions that I have to live with.”

It was not Peden’s fault that the battery was unsafe or that it was so easy to buy online. Picking up his phone, he showed that within seconds he was being targeted with adverts on social media for similar secondhand batteries with no safety warnings or certification.

The Department of Business and Trade said a Whitehall taskforce had been set up to tackle the problem and research had been commissioned to understand the cause of fires in lithium batteries.

Peden is frustrated by the delays. “The longer they take to regulate, the more the bodies will pile up,” he said. He urged the next government to introduce ebike safety laws as soon as it came into office. “If my story doesn’t show the desperate need for a change in the regulation, then I don’t know what will.”

In a campaign video for Electrical Safety First, he said: “We are trusting the government that they are safe, but they are not. They need to be regulated, they need to be checked. Change the rules to save someone’s life.”

Lesley Rudd, ESF’s chief executive, said: “Across the country people are dying because of these fires, and people like Scott are left living with the grief and devastation. The status quo is killing people and ruining lives.”

Hope that sodium battery powered e-bikes hit the market soon. They'll have lower range, but they don't explode or catch fire like Lithium batteries.

[–] [email protected] 0 points 1 month ago (1 children)

I'm seeing that sodium ion batteries have lower energy density than lithium ion batteries. I'm not a chemist. So I had to do some searches and it appears this is measured by weight, not volume.

Using hypothetical numbers to explain my question imagine that...

  • lithium battery weighs 1kg and has 5 stored energy units
  • sodium battery weighs 3kg and has 5 stored energy units

How does this effect the space needed for the battery? If the physical density (not energy density) of sodium was 10 higher, maybe the battery weighs 3 times as much but because it is dense, that weight fits in a smaller (say 100 cubic units), heavier package. Conversely, if the physical density was 10 times lower the battery would be 3 times heavier but be 1000 cubic units.

My question is basically what is the difference in physical density of the materials (kg per cm^2)?

Unfortunately, ddg and google keep assuming I want to know about energy density.

[–] [email protected] 0 points 1 month ago (1 children)

That's a good question, and I'm not really able to give a solid answer on that, but I think the measurement you're looking for is volumetric density. At least according to the wikipedia article for sodium batteries, sodium-ion batteries have roughly half the volumetric density of Lithium-ion (though I'm unsure how old that data is), so a sodium battery would need to be twice the physical size to equal the same amount of usable energy.

If there was a significant cost savings with the sodium ion option, I think that could be a reasonable tradeoff until improvements are made to make sodium-ion's density more similar to lithium.

[–] [email protected] 0 points 1 month ago

I imagine then that for an equivalent battery our sodium battery would weight 3 times as much and take up twice as much space as a lithium battery (plus any extra weight a larger housing or heavier mounting brackets add). Most of the ebikes I've ridden have batteries approximately the size of a 2L of cola.

My battery would no longer fit fully in the downtube, or would have to be paired with a second battery. Perhaps putting it in the frame triangle would work. For larger bikes, like cargo bikes, I could see a large flat battery being put in the bottom of the wheelbarrow part without really being that noticeable. Even if only half of bikes changed over, it would still be a win.

I've also visited a lithium mining area in the salt flats and what we've done to the indigenous folks' land, communities, and to the people themselves is abhorrent. We can do better. Let's hope these sodium batteries become available sooner rather than later, especially for circumstances where the weight/size are less of an issue.

If there is a god, please give that man as much comfort as possible.

A sentiment I can get behind

[–] [email protected] 0 points 4 months ago

A decent stopgap could be to ship LiPo battery protection bags with every battery - they're comparatively cheap as hell and while they don't stop smoke (which was the issue in this case), they can greatly reduce fire spread and burn rates.

[–] [email protected] 0 points 4 months ago* (last edited 4 months ago) (1 children)

The answer to people storing their ebikes in their houses and getting themselves killed isn't to ban ebikes or make ebikes harder to get. Because then they just drive a car and get someone else killed. The answer is parking minimums. We need secure, convenient, and electrified outdoor bike parking at every residence. It should be the law. If an ebike catches fire outside, nobody's going to die.

[–] [email protected] 0 points 4 months ago (3 children)

It would be a lot cheaper to stop allowing no brand cheap crap with no accountability to be drop shipped from China. There are clear and well defined safety standards for lithium batteries and they're just being ignored. They won't prevent 100% of failures but 99.9% if they're followed.

[–] [email protected] 0 points 4 months ago

Nawww, let's blame the victims!!! 🙃

I really don't get people like that one dude. Someone makes a shitty battery and they turn around screaming yOuRe sTuPiD FoR ChArGiNg sUcH A DaNgErOuS ThInG In yOuR HoMe.

Can you imagine this poor dude? Lost his wife and two children. He's got to live with that. And the internet is screaming "you're stupid!!!"

Check please.

If it doesn't have a valid CE marking all that shit should be turned back at the border. There's no excuse for deathtraps to be sold in first world countries.

It really doesn't cost much to make this stuff safe.

[–] [email protected] 0 points 4 months ago (1 children)

You know how easy it is to fake inspected stamps and certificates? That's SOP for these clowns. You sweet summer child.

[–] [email protected] 0 points 4 months ago

I'm not talking about checking a stamp. I'm talking about a full inspections of an item taken at random from a batch. And charging them for it.

And unless you have an office in Europe where we can go and arrest you for fraud when it turns out not every batch follows the rules, it will happen to every batch as well.

[–] [email protected] 0 points 4 months ago

I don't care about cheap, I care about preventing mass extinction. Bike parking minimums will make e-bikes feasible for a greater range of people and reduce car use.

[–] [email protected] 0 points 4 months ago

Choose LiFePO, it's way safer than LiPo.

I work at a bike shop. This is the main reason why we refuse to service cheap, direct to consumer bikes. Plus, most use non standard parts, underpowered brakes, etc. They're non serviceable death traps

I feel terrible for that guy. Sadly most consumers don't know. They see one bike that's $1200 while most are $4000+ and they think they're getting a deal

[–] [email protected] 0 points 4 months ago (1 children)

I'm sorry but no sane individual should pay 4000$ for a bike. That's insane.

[–] [email protected] 0 points 4 months ago

If it's your interest, why not? People buy all sorts of stupid shit. At least my expensive, stupid shit keeps me in shape.

My road bike and mountain bikes aren't even top tier and both individually coast twice that. A new, tricked out Moots or SWorks is $15k.

A $4k eBike can replace your car and save tons more in the long run

[–] [email protected] 0 points 4 months ago (2 children)

I moved into my local city and really want to pick up an e-bike so I can get around easier and don't have to drive. I was hoping to spend less than $2000, but stories and comment sections like this make me pause. What should an e-bike cost, and do you have any recommendations on reputable dealers? I'd really appreciate any information you might have.

[–] [email protected] 0 points 1 month ago (1 children)

I spent around $3750 for my ebike. As an example of what that gets you, I tested a lot of bikes, cheap and expensive and here's what stood out to me:

  • Torque sensing rather than cadence sensing for pedal activation means my bikes torque scales with my own. A cheap bike just goes "oh, the pedals moved a half rotation, engage electric motorcycle mode". This makes my bike feel more connected, it's the difference between putting on an exoskeleton versus driving a walking robot from a cockpit.
  • Torque specs and maintenance info clearly listed, bike shop can get spare parts. While I'd like to see parts availability commitments become more common, right now the best you can do is go with a well known brand.
  • Frame geometry is often better on bikes from bike brands making bikes with tech than tech startups making bikes. This relates directly to on-bike comfort
  • As we're all discussing here, battery quality can make a difference in safety and functionality.

I hope this helps. I still think you can get a reputable bike at a good price, but I would generally skip the Temu, Amazon, no name rebrand ebikes out of concern for their quality.

Funny thing is I was actually recently given an e-bike for my birthday and it's from rad-power bikes. Odds I end up dead?

[–] [email protected] 0 points 1 month ago (1 children)

Probably pretty low.

Congrats in the bike! I hope you have fun zipping all over town. If bike theft is a thing where you live, grab the serial number andsee about getting it added to your insurance under a personal articles policy. Mine is only $100/yr and I feel so much better about leaving it locked up out of my sight for a second.

[–] [email protected] 0 points 1 month ago (1 children)

Yeah, e-bikes are pretty common targets for theft, so I will definitely be getting insurance on it. The insurance from the manufacturer only covered damage, not theft, so if you don't mind me asking, who do you use?

[–] [email protected] 0 points 1 month ago

I have never had to make a claim on my bikes, so I can't make a recommendation, but the insurance through my car insurance/ home insurance company.

[–] [email protected] 0 points 4 months ago

Get something mainstream. As long as the bike has one of the following engine systems: Shimano, Bosch, Specialized, Mahle, TQ and a couple others I can't think of off hand. Any of the other weird ones are often impossible to diagnose and work on

Bafang motors are a crap shoot. They make a couple that are okay, but also a lot of low end, sketchy systems.

Electra has a couple of cheaper models that come in under $2k. While the motors themselves aren't unsafe, I think the bikes themselves have underpowered brakes and the like. Something like the Specialized Globe is $2800 and is a pretty solid, utilitarian platform.

Avoid Rad Power, Lectric, Super 73, and any of the other weird, fly by night direct to consumer Asian brands

Lithium battery fires are terrifying, there was one in January on the Toronto subway. Thank goodness they were able to evacuate everyone before it exploded, one of my classmates was on a different car when it happened and he said he heard the explosion as he was leaving the area.

I also learned that people apparently packed their laptops/iPads/portable consoles in their checked baggage, and I've never had peace of mind on a flight since that day.

[–] [email protected] 0 points 4 months ago

There are three reasons you probably don't need to worry about those checked devices.

First, ebikes have way larger batteries than mobile electronics. The first laptop that came up when searching for laptops with large batteries had 80 Wh. The smallest ebike battery that appears in the first article searching for "ebike battery capacity" is 400 Wh.

Second, these problems tend to occur in uncertified third-party knock-offs. Your Lenovo or HP or Apple laptop, or even your Shimano or Bosch ebike, are much, much less likely to fail than a cheap eBay or Amazon battery.

Finally, and possibly most importantly, you are at highest risk while charging, slightly less risk while in use, and lowest risk when off. A device switched off in an aeroplane cabin is about as safe as it can be.

Not surprised in the least..and people keep demanding and screaming for Chinese EVs because they are cheap. Lovely.
