Lyft Says It Will Start Recycling E-Bike and Scooter Batteries
Lyft plans to start recycling its e-bike and scooter batters through a newly announced partnership with Redwood Materials, as first reported by The Verge. Lyft owns 12 different municipal bike share programs—like New York City’s Citi Bike and San Francisco’s Bay Wheels—in addition to its scooter program in four…
E-Bike Batteries Have Caused 200 Fires In New York
As the densest city in America, New York is a micro-mobility haven. Here, small electric vehicles aren’t toys for weekend jaunts but vital tools for the estimated 65,000 delivery workers trying to scrape a living through low-paying apps. There are thousands of choices today if you want an e-bike, e-scooter or e-moped. Some of the high-end, name-brand machines are sold in beautiful downtown showrooms for well over $5,000. But many of the vehicles used by New York City’s workers come from unknown manufacturers and are sold online or through small shops for between $1,000 and $2,000. Nearly all of these vehicles are powered by lithium ion battery packs, which contain tightly bundled cells that store energy as flammable chemicals. Typically, the cells are kept in sync by a piece of electronic circuitry called a battery management system, or BMS, which makes sure that the cells don’t overcharge or release too much energy at once. But that careful balance can get disrupted due to damage, wear or faulty manufacturing, sometimes with dangerous results.
Lawmakers are worried too. The authority that manages New York’s public housing proposed an e-bike ban on its property this year but backed down after an outcry from low-income residents. On Monday, the city council held a hearing where legislators touted bills to combat the battery fires, including a proposal to outlaw the sale of secondhand electric vehicle batteries, and another to ban all batteries that haven’t been approved by a nationally recognized testing lab. If passed, that measure would force riders to use batteries such as those certified by the Illinois-based Underwriters Laboratory (UL), which subjects e-bikes and their batteries to rigorous testing on issues ranging from their performance under extreme temperatures to how easily fire spreads between cells. Manufacturers have to pay a “nominal” cost to undergo testing, said Robert Slone, UL’s chief scientist, but “we see a lot of manufacturers showing interest in certifying the batteries”. UL sent a statement to the city council supporting the proposed measures, though it said a total ban on used batteries could be overkill: “When done correctly, batteries can be safely repurposed.” Something else that would make a big difference for workers is better intel. “Each fire happened, they say it’s an e-bike, but we don’t know which one it is,” said Gustavo Ajche, the founder of Los Deliveristas Unidos, a prominent delivery worker labor group. “There’s a lot of missing information.”
What would be more useful, he said, would be if the fire department committed resources to testing and sharing details about which batteries were safe to use, so that workers could make more informed decisions.

Fires from Exploding E-Bike Batteries Nearly Doubled This Year in New York City
Sometimes, it does so on the street, but more often, it happens when the owner is recharging the lithium ion battery. A mismatched charger won’t always turn off automatically when the battery’s fully charged, and keeps heating up. Or, the highly flammable electrolyte inside the battery’s cells leaks out of its casing and ignites, setting off a chain reaction.
“These bikes when they fail, they fail like a blowtorch,” said Dan Flynn, the chief fire marshal at the New York Fire Department. “We’ve seen incidents where people have described them as explosive — incidents where they actually have so much power, they’re actually blowing walls down in between rooms and apartments.”
And these fires are getting more frequent.
As of Friday, the FDNY investigated 174 battery fires, putting 2022 on track to double the number of fires that occurred last year (104) and quadruple the number from 2020 (44). So far this year, six people have died in e-bike-related fires and 93 people were injured, up from four deaths and 79 injuries last year.

‘The E-Bike Is a Monstrosity’
Bikes have always worn many helmets: cycling as exercise, cycling as leisure, cycling as sport, cycling as transit. These roles often conflict with one another. The commuter sneers at the spinner, who pedals pointlessly to nowhere. The leisure-rider spurs the Lycra-racer, who endangers pedestrians and inspires drivers to hate cyclists. E-bikes continue, and worsen, that disorder by jumbling up aspects of bicycles and motorcycles. Strapping a motor to a bike turns out to alter more than just speed and exertion. It produces a chameleon that takes on, under various conditions, both the best and worst features of a variety of transportation technologies. The result is less an evolution of a two-wheeled machine than a pastiche of the many things such a device represents. It’s a monster made from bicycles and motorbikes.
Here’s what I mean: A bike can be exerting to ride, which is both a feature and a defect. Biking to the store or office offers an opportunity to move one’s body instead of spreading it into the seat of a car (or even a train). Depending on distance and terrain, biking can raise your heart rate, making it an effective workout. But working out can make you sweaty and smelly, a feature incompatible with using a bike for commuting (or even errands). E-bikes, by contrast, allow a motor to assist the rider, reducing exertion and thereby delivering you to the office or cheesemonger with a dry brow and dry armpits. But in exchange for that polish, an e-bike rider gets less exercise than the equivalent trip under full pedal. […] The truth will differ based on circumstance, but the result is the same: a weird ambiguity. An e-bike sure seems like a way to cheat at exercise, even if it really facilitates it.
