London Bans Most E-Bikes on Public Transport Over Fire Risk (theguardian.com)

(Wednesday March 26, 2025 @12:45PM (msmash) from the PSA dept.)


Transport for London will [1]ban most e-bikes across its network from March 31 amid growing safety concerns over battery fires, the transport authority announced on Wednesday. The ban, covering London Underground, Overground, Elizabeth Line and DLR trains, exempts only folding e-bikes, which are considered less likely to have been modified and pose a reduced safety risk.

TfL implemented the measure following union strike threats after several incidents, including an e-bike that exploded into flames at Rayners Lane Underground platform last month. The train drivers' union Aslef said the incident could have caused mass casualties.

30 kg per kWh versus 6 kg per kWh is a big deal.

The e-bike trade in program takes old models and scraps them. And then citizens can use credits to purchase a variety of new e-bikes, some of them are lead-acid but you can also buy other battery technologies (I believe some of the models are LiFePO). [1]similar article [chinadailyhk.com]

The main reason MOC subsidized lead acid bicycles is because they are the cheapest one, even if their performance is not great. The goal is to make sure people trading in bikes can afford to get a

That's mostly for scooters though, not eBikes as we know them. They have had electric scooters with lead acid batteries for decades, so there is less interest in eBikes from Chinese consumers it seems.

The problem bikes in London are DIY ones. The well designed products are fine, it's the people getting cheap kits with low cost batteries and inadequate safety protections that are catching fire.

I have two possible answers. One, the batteries in cell phones, laptops, and watches are small enough that those going up in flames aren't likely to kill anyone. Two, give it time.

Aren't the rules now that lithium batteries can't be in checked bags? If in the luggage hold a battery fire would be difficult to reach and contain. If in the cabin there's more people around to breathe in the fumes or what not but those people can also blast it with fire retardant.

Lithium batteries need to be in the carry on for this reason. An incendiary device on a plane is not of a major concern providing it is in the cabin where it is easily accessible and isolated. All history of planes downed due to batteries caused by lithium fires have been the result of the fire starting in an inaccessible place.

There are restrictions on Li-ion batteries for planes. First of all, they cannot be checked in and must be carry-on. Second the battery must be 100Wh or smaller. Most e-bike batteries are 300+ Wh.

That is true. Or, at least the batteries are not allowed to be checked in, so the following questions that bother are: is anyone paying attention to those restrictions? how many people even know/care what a Li-ion battery is, and which of their devices have one? are the airlines checking the checked luggage for Li-ion batteries?

It's more a case of a small device being able to be effectively manoeuvred in case of emergency. If your folding ebike catches fire you can yeet it out of the door at the next station. When a full sized e-bike catches fire good luck grabbing that burning mass and trying to carefully squeeze it past the chairs and through the door.

E-bikes provide some assistance for things like hills and long distance. They are not meant to be a fully motorized vehicle. I suppose maybe someone could use an e-bike for 100% pedaling but the battery would drain fast and the range would be terrible. As such it is not a black and white solution where it is e-bike for 100% of the ride vs a bicycle for 0%. There is an area in between for partial assistance.

I guess the e-bikes I see are much different than in other parts of the world...?

The ones I see are like BIG mountain bikes, thick tires and they aren't being pedaled...zipping along at a pretty quick speed.

Not as fast as a true motorcycle...but close to maybe a very small scooter....

But again, I'm not seeing anything that is pedal-assist...these things I see are using full electri

A battery wrapped in 2 layers of sheet metal with a small air gap and limited venting like a small oven would contain a fire. These bikes can be safer and with little added weight, so the government should define what safe looks like and only allow bikes that meet this standard on public transit. The same thing goes for chargers and apartment fires.
