XLime Is Bringing Its New, More Eco-Friendly Scooters to LA
The first Lime electric scooters hit the streets of Los Angeles in June 2018, some nine months after rival e-scooter startup Bird first took flight in Santa Monica. In the years since, Lime has battled Bird and a wave of other micromobility operators for market dominance—seeking to transform the urban transportation landscape while facing losses, regulatory backlash and even destructive anti-scooter sentiment.
Now, Lime is upping the ante in the great e-scooter wars once again by bringing its latest e-scooter model—the Lime Gen4—to the streets of Los Angeles, with the goal of replacing all 7,000-plus vehicles in its L.A. fleet by this summer. Lime has already rolled out the Gen4 globally in markets from Denver to London.
The San Francisco-based company told dot.LA that it designed the Gen4 to be more eco- and user-friendly—with a swappable battery, bigger wheels, a lower center of gravity and swept-back handlebars akin to a bicycle.
“As of [the week of April 17], you'll start to see them in Hollywood, West Hollywood and in some of the Hills area,” said Alyssa Edelen, Lime’s general manager for the southwest region.

The Next Generation
Originally a bike-sharing company, Lime launched its e-scooter fleet in 2017 with the Segway Ninebot, a popular choice for operators at the time. However, early e-scooters were not built for the harsh conditions of shared use. One 2018 study by Quartz of Bird scooters in Louisville, Ky., found that the vehicles lasted less than 29 days on average before breaking down or falling prey to vandalism or theft.
The next Lime generation to hit L.A. streets in 2018 was the Gen2.5, a hardier model built to last 18-to-24 months. Then last year, the company swapped out the Gen2.5 for Okai scooters inherited through its 2020 acquisition of Uber’s micromobility business, Jump. Instead of recycling the Jump scooters, Lime wanted to deploy them in select markets.
Now, Lime says that its latest model—designed and manufactured completely in-house—is built to last for up to five years. In comparison, competitor Bird’s latest model, the Bird Three, has an estimated shelf life of two years.
Lime didn’t share details on how much the company invested in R&D for the Gen4. The scooter was initially developed by Jump, with Lime continuing the work after acquiring the former Uber subsidiary.
How Eco-Friendly Are E-Scooters?
The lifespan of an e-scooter doesn’t only affect a company’s bottom line—it also has a significant impact on sustainability.
In a 2019 study conducted at North Carolina State University, researchers calculated the life-cycle emissions of shared e-scooters. The study found that although riding one was better for the environment than driving a car, it was not as green as riding an electric bike or even taking a gasoline-powered bus.
And that’s not just because of the energy required to charge e-scooters, which represented only 5% of their total emissions. According to the study, most of the greenhouse gas emissions from shared micromobility comes from manufacturing a device’s parts, as well as the logistics of collecting and charging the vehicles. In other words: the longer a scooter’s lifespan and the easier it is to charge it, the lower its carbon footprint will be
To address the environmental impact of charging scooters and returning them to the streets, Lime and other micromobility operators are now embracing models that feature swappable batteries. According to Lime, the Gen4’s swappable battery makes the charging process more streamlined and energy-efficient; vehicles no longer need to be transported to a warehouse for charging. Lime’s new Gen4 e-bike model is also using the same swappable battery.
While some competitors, like Bird and Superpedestrian, have called into question the environmental benefits of swappable batteries, the industry at large seems to be trending in their favor. Veo CEO Candice Xie told dot.LA earlier this year that the micromobility firm is using its Cosmo seated scooter to tow trailers filled with batteries that are swapped into its vehicles in Santa Monica.
“We don't need to collect all the devices back to the warehouse to charge and then roll [them] out again,” Xie said. “All we need to do is swap the battery on site, and that increases our efficiency and reduces our operations by 40-to-50% compared to other vendors.”
West Hollywood-based Wheels is testing out a similar strategy in Austin, Texas, where it’s using its own electric seated scooter to swap batteries and service its vehicles, with plans to implement this method in L.A. Meanwhile, a Lyft spokesperson said many of the company’s maintenance teams are using electric golf carts and e-cargo tricycles to swap batteries on its own micromobility vehicles.
Lime has yet to use electric vehicles in L.A. for charging and maintenance operations, but said it’s in the process of acquiring and implementing them.

The Adoption Issue
Lime’s more eco-friendly approach comes as Angelenos are increasingly turning to shared transit options to avoid record-high gas prices. As of mid-April, Lime had seen its ridership in L.A. grow “about 35%” in the preceding two-to-three weeks, Edelen said. The company’s Lime Access equity program, which provides discounted rides to underserved Angelenos, logged 12,000 rides in March, the highest number since its inception.
But despite the lofty environmental goals of micromobility companies—Lime is aiming to have a zero-emissions operations fleet by 2030—some experts note that their impact on the greater transportation sector is limited.
In a study released in February, researchers at Carnegie Mellon University examined the environmental impact of replacing short car trips with micromobility vehicles during peak travel hours. For context, in the U.S., almost 50% of car rides are three miles or less—a sweet spot for bicycles, e-bikes and scooters. Using the city of Seattle as a model and factoring in weather conditions, trip type and user demographics, the study found that only 18% of short car trips could be replaced, leading to just a 2% reduction in overall emissions.
Carnegie Mellon assistant professor Corey Harper, a co-author of the study, noted that most carbon emissions come from long-distance travel. “We have a lot more work to do if you really want to reduce emissions in our transportation sector,” Harper told dot.LA. “Because even if we were able to fulfill every single trip that could be done by bike or scooter, 98% of emissions would still be there.”
The study suggests that e-scooters have the most impact when combined with public transit as a first- and last-mile option. Choosing to take an e-scooter instead of driving a car has other benefits as well, such as reducing traffic congestion. Ultimately, Harper believes that for people to choose more eco-friendly transportation options, companies and cities have to make those modes more appealing to riders.
Lime is gambling that its redesigned e-scooter—with its bigger wheels, swept-back handlebars and improved suspension—will attract even more riders, and not just because it’s the more eco-friendly option.
In a promising sign, Edelen said that L.A. users are riding the Gen4 longer and rating it higher compared to the previous model.
“Ridership is up compared to last year and previous years,” she noted. “Comparing this model to our Okai, we are seeing close to double the utilization.”

This Torrance Startup Just Raised $1B to Mass-Produce Hypersonic Missiles
🔦 Spotlight
Happy Friday, Los Angeles.
Castelion has spent the past four years trying to prove that hypersonic missiles do not need to take decades to develop or cost so much that the military can only afford a limited supply.
Now comes the harder part: producing them at scale.
The Torrance-based defense startup raised a $1B Series C at a $13B valuation. The financing includes $800M in equity and a $250M revolving credit facility, making it one of the largest recent raises for an LA defense technology company.
JPMorganChase’s Strategic Investment Group, Andreessen Horowitz and Carlyle co-led the round. Lightspeed Venture Partners, Lavrock Ventures, Altimeter, General Catalyst, T. Rowe Price and LA-based Interlagos Capital also participated.
Castelion will use the capital to ramp production of Blackbeard, its low-cost hypersonic strike missile, while developing a longer-range precision weapon and new defensive systems. Hundreds of millions of dollars will go toward expanding manufacturing at Project Ranger, the company’s 1,000-acre production campus in New Mexico.

Blackbeard was designed in California, will be built in New Mexico and is expected to enter service in 2027. Castelion says it has already secured more than $500M in U.S. military contracts over the past 18 months and moved the missile from a clean-sheet concept to an official program in fewer than four years.
That timeline is central to Castelion’s pitch. Traditional defense programs are often associated with long development cycles, limited production runs and eye-watering costs. Castelion is applying the rapid testing and vertically integrated manufacturing approach popularized by commercial space companies to weapons production.
But a $13B valuation changes the standard. Castelion is no longer being judged as a promising startup with an impressive prototype. It is being funded like a company expected to become a major part of the American defense industrial base.
The question is no longer whether a startup can build a hypersonic missile. It is whether one can manufacture thousands of them without losing the speed, discipline and cost advantages that made it disruptive in the first place.
For LA’s defense ecosystem, that shift matters. The region has become home to a growing number of companies promising to modernize how America builds critical hardware. Castelion now has the capital, contracts and facilities to show what happens when that promise reaches the factory floor.
The next test will not be in a pitch deck. It will be in production.
