We need to talk about Rad Power Bikes’ new e-bike batteries
Electric bikes just may be the biggest transportation revolution of our generation, helping millions replace car usage with more affordable, more efficient alternatives. But there’s no denying that concerns have been swirling about the safety of e-bike batteries, even if such fire fears have primarily been overblown by much of the media.
Leading electric bicycle maker Rad Power Bikes has just unveiled its new “Safe Shield Battery” in an effort to mitigate worries over e-bike battery safety. And it’s something we need to talk about.
The whole underlying issue here is based on the fact that e-bike batteries are usually comprised of dozens of smaller, energy-dense lithium-ion battery cells. Those cells are similar – and sometimes identical – to the battery cells used in everything from electric cars to power tool battery packs.
The individual battery cells store lots of energy and are generally quite safe. However, danger can occur when the cells are punctured or short-circuited, with the latter often happening when water makes its way into battery packs over time. Well-made e-bike batteries use several methods to mitigate these risks, and the result is that battery fires are exceedingly rare. Even in e-bikes, which seem to unfairly receive the brunt of lithium-ion battery fire scaremongering, such fires occur in a tiny, tiny fraction of a percent of e-bikes.
To put things into perspective, New York City often gets labeled as the epicenter of e-bike fires, yet New Yorkers are somewhere around 5x more likely to die on the subway than from an e-bike fire.
However rare though, e-bike fires can and do occur in poorly made batteries or in battery packs that have been abused, damaged, or otherwise misused. And that’s exactly what it looks like Rad Power Bikes set out to solve with its new Safe Shield e-bike batteries.
The secret sauce in Rad’s batteries isn’t actually the battery cells themselves. Those are fairly standard cells like you’ll find in many other e-bike batteries. The major difference is how the battery packs are constructed.
They use a method known as potting, which basically encapsulates electronics in a waterproof resin barrier. It’s common in electronics that will live much of their lives outdoors, as it seals the sensitive components from moisture.
Remember that mosquito from Jurassic Park that was encased in tree resin amber? That’s kind of the idea with potted batteries, just with a urethane resin instead of tree sap. The battery pack already uses quality construction methods, but then to top it off, the entire thing is filled with resin that makes it impermeable to water – or intruding fingers, tools, or anything else. It’s forever sealed away from the world (though Rad says it’s still recyclable in their battery recycling program).
But it’s not just any resin, the idea is that it is also thermally insulating, which means that if one battery cell ever did go rouge and start overheating (an incredibly, incredibly rare event in well-made battery cells), the barrier would help protect any nearby cells from joining in and developing what is known as a “thermal runaway” condition that is what ultimately leads to the spread of most battery fires.
We spoke to one of the country’s leading battery experts Luke Workman on our Wheel-E podcast last year, who has often performed forensic evaluations in the aftermath of battery fires. When we asked him if there was anything that could be done to help mitigate the fire risks we were seeing in the e-bike industry, such as the widespread adoption of UL certification, he had a simple answer: “Potting.”
Workman explained that he’s performed post-fire forensic analysis on plenty of UL-certified battery packs, indicating that such certification isn’t a guarantee of safety. “You can pass UL water ingress tests with a bit of strategically placed tape over the battery seams,” he explained at the time. But potting was the truly safest method of building batteries that wasn’t intended to merely pass a certification test, but rather to actually ensure the battery cells were isolated and protected.
At the time, there was just one major company producing potted e-bike batteries, Luna Cycle, but it hasn’t gained significant traction anywhere else in the e-bike industry.
At least not until now.
With Rad Power Bikes adopting potted battery design practices, the entire industry has been put on notice. Until new technologies like fireproof solid-state batteries become commonplace, potted batteries are the single best defense against battery fires. And with one of the largest e-bike retailers in the country hopping aboard the potted train, others are all but sure to follow.
Rad has a history of setting examples that are quickly copied throughout the US e-bike industry. New e-bike models like the RadRunner spurred several copycats and jumpstarted the utility e-bike market. Rad’s expansions into several large brick-and-mortar stores pre-empted a major push by several other US e-bike companies to expand dealer networks with independent bike shops. Rad’s electric trike was quickly followed by several other competitors seeking to undercut its price.
In none of these examples was Rad the first e-bike company to make a major move, but it was the first big e-bike company to do so, and thus helped shift the industry each time. And while there’s no guarantee how the industry will react, especially in a year where e-bike sales have lagged behind the post-pandemic boom, there’s no doubt that a major e-bike maker finally adopting potted battery technology is a sign of where the industry is headed. How long it takes us to get there though, that’s anyone’s guess.

Electric vehicles’ share of the market continues to climb in America’s second city, with BEV registrations up more than 50% in the first quarter of 2025 compared with the same period last year. Great news, but charging hasn’t up – but a new plan from Chicago Department of Transportation aims to build up enough infrastructure for the city to keep up.
In a bid to keep up with the rapid growth of EVs, Chicago Department of Transportation (CDOT is currently seeking public feedback on a plan called “Chicago Moves Electric Framework.” The city’s first such plan, it outlines initiatives that include a curbside charging pilot through the city’s utility, ComEd, and expanded charging access in key areas throughout the city.
Unlike other such plans, however, the new plan aims to focus on bringing electric vehicle charging to EIEC and low income communities, too.
“Through this framework, we are setting clear goals and identifying solutions that reflect the voices of our residents, communities, and regional partners,” said CDOT Commissioner Tom Carney. “By prioritizing equity and public input, we’re creating a roadmap for electric transportation that serves every neighborhood and helps drive down emissions across Chicago.”
Neighborhoods on the south and west sides of Chicago experience a disproportionate amount of air pollution and diesel emissions, largely due to vehicle emissions according to CDOT. Despite that, most of Chicago’s public charging stations are clustered in higher-income areas while just 7.8% are in environmental justice neighborhoods that face higher environmental burdens.
“Too often, communities facing the greatest economic and transportation barriers also experience the most air pollution,” explains Chicago Mayor Brandon Johnson. “By prioritizing investments in historically underserved areas and making clean transportation options more affordable and accessible, we can improve both mobility and public health.”
The Framework identifies other near-term policy objectives, as well – such as streamlining the EV charger installation process for businesses and residents and implementing “Low-Emission Zones” in areas disproportionately impacted by air pollution by limiting, or even restricting, access to conventional medium- and heavy-duty vehicles during peak hours.
The Chicago Moves Electric Framework includes the installation of Level 2 and DC fast charging stations in public locations such as libraries and Chicago’s Midway Airport, “supporting not only personal EVs but also electric taxis, ride-hail and commercial fleets.”
Chicago has a goal of installing 2,500 public passenger EV charging stations and electrifying the city’s entire municipal vehicle fleet by 2035.
Electrek’s Take
I hate to sound like a bed-wetting liberal here, guys, but Chicago is getting EVs absolutely right with big utility incentives on both vehicles and infrastructure, a governor willing to stand behind smart environmental policy, and a solid push for more and better infrastructure in the areas where they’ll do the most good. They’re even thinking of the children.
Here’s hoping more cities follow suit.

With a fully-enclosed, G-Wagen-inspired body and an 80 mile electric range, the Bodo G-Wagon golf cart is the NEV you need when you decide it’s time to get serous one-upping the rest of the Palm Beach country clubbers.
If you love the look of the $230,000 Mercedes-Benz G580 off-roader, but think the 579 hp, 6,800 lb. electric 4×4 is probably overkill for occasional trips to the golf course and country club, this G-Wagen-inspired golf cart might be just what you’re looking for.
The shiny black 2024 Bodo G-Wagon sold at Mecum Auctions last month for $31,900, which seems like it might not be a lot of money to the sort of person who decides to take a flyer on a goofy, limited-use EV that ships with real, metal doors, power windows, heating and air conditioning, fully digital instrument cluster and infotainment, and a “posh,” caramel leather interior.
It even has windshield wipers, power steering, and a rear-seat entertainment system that’s built into the front headrests!
It’s really nice in there
Under the hood, the Bodo packs a 15 kW (20 hp) electric motor drawing power from a 10 kWh li-ion battery that won’t deliver a scorching 0-60 mph time (it only goes 35), but will deliver you and your buddies from one end of any golf course in North America and back several times over, thanks to the G-Wagon’s 80 mile range.
The official Mecum Auctions listing goes into a bit more detail, and I’ve included it here, in case it gets deleted after a while and you’re just finding this for the first time in 2027:
Be the envy of any country club or golf community showing up with this 2024 Bodo G-Wagon Golf Cart. Perhaps more appropriately known as an E-Wagon, this baby G-Wagon is powered by a 15kW motor with a 10kWh lithium battery. Boasting an 80-mile range and a 35 MPH top speed, the Bodo is an enclosed, luxury golf cart that pampers occupants with heating and air conditioning, rear-seat entertainment, power windows, power locks and a posh, caramel-colored interior. With the Bodo fitted with power steering and 4-wheel power disc brakes with brake boost, drivers will think they’re in a full-size G-Wagon, thanks to the multiscreen entertainment cluster, the rearview camera, windshield wipers, turn signals, running lights and so much more.
Finished in black with the right amount of brightwork, the overall vibe is one of jaw-dropping, smile-inducing fun. While the Bodo would be an excellent choice for any golf community, it should also prove to be hugely popular around a race track or car condo community as well, or maybe even a neighborhood with its own airplane runways. Over the past decade in particular, the demand for unique, luxury golf carts has been on the rise, and understandably so. The number of luxury communities with specific interests in sports, aero and auto has also been on the rise, with people buying homes in these exclusive locations to better engage with like-minded people. All too often a golf cart is the perfect way to get around these gated neighborhoods, and this one is enclosed, comes with the amenities of a full-size car and is infinitely more stylish.
You can check out a few more photos of the 2024 Bodo G-Wagon golf cart that sold at Mecum, below – and if you want one for yourself, you’re in luck! I found this brand-new 2025 “G600 E-Wagon” (in white) for $23,900 at Gulf Carts in Santa Rosa Beach, Florida. Head on down to the comments and let us know if you buy it.
