London Bans Most E-Bikes on Public Transport Over Fire Risk (theguardian.com) 77

Transport for London will 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.

      The only thing Transport for London can ban you from buying is a public transport ticket, or ban you from riding on it. Many countries have rules banning various forms of dangerous ebikes. In those countries the rules are as you can expect, poorly enforced because of course they are, this shit is insanely hard to police.

    • According to the London Fire Brigade: In 2024, London Fire Brigade recorded 142 fires involving e-bikes along with 29 e-scooters. This means that on average, there was an e-bike or e-scooter fire once every other day.

      Other major cities will cite similar stats. NYC, in particular, is faced with significant damage to homes and loss of life related to ebike fires. In particular due to their popularity with delivery drivers, but also their use by the general population as a form of transportation.

      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). similar article [chinadailyhk.com]

    • by AmiMoJo ( 196126 )

      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.

      • These are also almost all illegal imports because they don't remotely satisfy UKCA or CE regulations, sold by the likes of Amazon. Oh as an added bonus they also are used to almost exclusively make unlicensed electric motorcycles rather than legal ebikes.

        For some reason none of the governments seem remotely interested in doing anything about it, and Amazon is happy to cream off money from a flood of illegal shit.

  • If Lithium battery packs can be turned into incendiary devices by anybody who knows what they are doing... then why are they still allowed on airplanes?
    • 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.

      If Lithium battery packs can be turned into incendiary devices by anybody who knows what they are doing... then why are they still allowed on airplanes?

      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.

      • by AmiMoJo ( 196126 )

        You can take lithium batteries in the hold too, where they are inaccessible. Some aircraft have fire extinguishing systems in the hold, but most rely on stopping the fire spreading and just let it burn itself out.

        The rules are a bit complicated, but basically devices like laptops and phones can be put in the hold, but "spare" batteries like portable phone chargers and the like cannot: https://www.caa.co.uk/passenge... [caa.co.uk]

        • You can take lithium batteries in the hold too, where they are inaccessible.

          You're stretching the word "batteries" a bit there. Most (not all) airlines allow small devices (several laptops on the market don't qualify) in the hold providing they are powered off completely enclosed. Devices with removable batteries almost universally have a requirement where you to take the battery out and carry the battery in the cabin.

          But the entire premise is silly. If you know what you're doing you can turn your laptop into a bomb as well, and throw that into the hold. Or... you know... just tell

        True,

        But I feel it should be noted that sometimes "fire" risk really means "arsehole" risk... Fire is just the way you say that without saying it.

        TFL manages millions of journeys per day, 4 million on the tube alone. This means trains are often packed with little to no spare room for an entitled e-biker to bring his massive bike on the tube. Non-foldable bikes are already banned on the tube at peak times. By classifying it as a fire risk, they're giving the arseholes who think it's fine to abuse the t

    • 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.
      • by dayL8 ( 184680 )

        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?

    • eBikes are prohibited on planes. Laptops and phones are allowed because a ban would discourage people from flying.

      Instead, we trust in the religious ritual of taking our shoes off before we can board in homage to John Frum and the cargo cult of air traffic security.

  • They really should only exclude Brompton, Britain's struggling folding bike pioneer. They are truly a national treasure.
    • 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.

      • I was somewhat being factitious, but there is probably some truth to it given the greenlight to building their new £100,000,000 expansion approval is reliant on public transport infrastructure to balance out the development's limited parking.

        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.

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

            The term e-bike is for any bicycle with motorized assistance. As such, the rider can choose some assistance to almost all assistance. It drains the battery quicker if the rider choose all motor.

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

            Every google search I see is a bicycle with pedals AND a motor. For e-bikes these days, the motor and battery are well hidden to where they are hardly noticeable.

            Hence, my thoughts of, if you're using a fully powered 'cycle'....go for a real motorcycle.....

                Electric motorcycles have existed since the early 1900s [wikipedia.org]. The most commercially successful variants I know have been electric scooters as the need for speed is reduced as well as the intended use of mostly light commuter traffic.

                but what I'm talking about do not have pedals and can be driven on the highway.

                That is, by definition, not an e-bike and not the subject of the article. The article is specifically talking about bicycles with a battery and motor being banned from using London public transportation. I am pretty sure motorcycles and scooters could not be ridden on London transpor

            Those are not bicycles. They are technically classified as electric off-road light motorcycles. An electric version of what we used to call dirt-bikes.
            Not legal for use on road or sidewalk or trail. It just is not enforced often.

            Average speed of a cyclist is just shy of 10 MPH, an e-bike can easily get up to 15 or 20 MPH for a sustained period.

        There are two reasons for ebikes. First,is if you have mobility issues. Older folks or out of shape people can use them to help them up hills and go distances. I'm totally cool with that. Are are also folks who claim they need them because they work in a 'professional' environment and 'can't arrive at work all sweaty'. I roll my eyes at them because I used to commute through Wash DC summers and was in the USAF,so I had to be in uniform and get judged on it.

      • In America, there's an oft repeated idea that half of all auto traffic is less than five miles and replacing these trips would halve pollution.

        While the exact math of the statistic is debatable, the central truth is not -- replacing those trips by walking, cycling, or public transportation would significantly decrease pollution.

        The argument can be further boosted by the reality that a significant portion of urban traffic (30-60%) is intentionally driving slower while looking for a parking space which

        E-bikes (at least in the USA) are a loophole in the vehicle/operator license and insurance laws. Don't need a drivers license (in spite of operating in and among other "real" vehicles). Bike doesn't need a license. Or insurance. So if some 12 year-old wants to mod one and hop on the highway right in front of, behind (or sometimes underneath) an 18 wheeler, there's not much the law can do. Particularly if any enforcement is seen by the likes of Critical Mass or other activist groups if it is seen to infringe

      • well, use the tried and true method where you actually pedal the damned thing and get exercise.

        Electric bike users tend to get more exercise, because they're willing to ride further and more often. It ends up replacing trips which would otherwise be done by car, where you get no exercise.

        They're also often used by elderly people who just aren't in good enough physical shape to ride a regular bike. Again, the alternative to an electric bike here isn't "more exercise on a non-electric bike", it's less exercise via driving.

  • 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.
  • Is the point of the rules to prevent fires--or prevent use of an alternate transportation means?
    • I think it's to prevent a strike shutting down London's transit system because the people who work there don't want to die in a potential underground inferno.

      There's no easy way to differentiate jinky eBikes from safe ones. Until this is possible, it's the best way to keep London moving.
  • Many higher-end E-bikes are almost indistinguishable from non-electrified bicycles at a casual glance. Batteries and motors are hidden in the frame. But I suppose those aren't at high risk anyways.

  • The vast majority of battery fires are when charging, very few are when the bike sits idle unless there is physical damage to the battery and that applies to folding bikes the same as any others. It makes no sense therefore on the overground, given the confined conditions in the underground where escape is more difficult, it may be appropriate to ban all e-bikes.
  • Everything else is switching to LFP batteries because of the fire hazard of LiIon batteries. But eBikes have not even started making the switch yet.

Your own mileage may vary.
