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.

Tesla announces 2025 holiday update with a few cool features

Tesla has officially announced its 2025 Holiday Update, and this year, the automaker is not using the usually bigger update for any groundbreaking stuff, but there are a few interesting new smaller features.

You will find the release notes in this article.

It’s that time of year again. Every December, Tesla bundles a bunch of features it has been working on into a “Holiday Update” to give owners something to play with over the break.

While previous years have focused on adding major apps like Apple Podcasts or Steam integration, the holiday updates have become gradually weaker over the last few years, and they now concentrate mainly on playful features with smaller tweaks and add-ons.

Kia is still offering over ,000 off its entire EV lineup

Kia is extending one of its biggest promotions yet, knocking over $10,000 off every EV in its lineup.

Kia knocks $10,000 off EV models

Who said electric vehicles would get more expensive after the $7,500 federal tax credit ended? Kia must not have gotten the memo.

Last month, Kia launched a new promotion, offering a $10,000 customer cash discount for all EVs, including the EV6, EV9, and Niro EV. The discount knocks nearly 25% off MSRP on Kia’s cheapest model, the Niro EV. On the entry-level EV6, it’s 23% off MSRP, while $10,000 off the EV9 is about an 18% discount.

The discounts ended on December 1, but Kia has extended them for at least another month. During its Season of New Tradition sales event, Kia is now offering even more savings.

The 2025 Kia EV6 and Niro EV are now eligible for up to $11,000 in customer cash, including a $10,000 cash back offer and a $1,000 retail bonus cash discount.

If you’re looking for something a little bigger, the 2026 EV9, Kia’s three-row electric SUV, is available with up to $10,500 in bonus cash.

If you choose to finance, Kia is offering 0% APR for up to 72 months, plus $3,500 APR Bonus Cash on the EV6 and Niro EV. The larger EV9 is available with 0% APR for up to 60 months with a $3,000 APR Bonus Cash offer.

New Holland C314 mini track loader gets the full electric treatment

New Holland C314 mini track loader gets the full electric treatment

New Holland Previews C314X Electric Mini Track Loader

New Holland’s already excellent C314 mini track loader is even better for 2026 thanks to the debut of a new, all electric version that offers quiet, low maintenance, and emission-free running for round-the-clock operation.

State and federal governments may still be hashing out emissions laws and ZEV requirements, but it’s the municipal governments that write quiet our laws and noise ordinances, and it’s those laws that construction crews are struggling to work around as they bid for lucrative urban jobs. New Holland understands those construction customers’ needs, and its new C314X Electric mini track loader (announced at last month’s Agritechnica) is designed specifically for them.

“We launched the C314 two years ago, and it has become known for its excellent features,” says Francesca Asteggiano, Europe Construction Brands. “Today, we’re developing an electric version to meet growing demand for quieter, more compact machines — reinforcing our commitment to sustainability and innovation.”

C314X Electric

New Holland’s C314X Electric is designed and built in-house as the zero-emission evolution of the diesel-powered C314, and is powered by a 23.5 kWh li-ion battery that sends power to three electric motors — two drive motors and a single hydraulic motor for the boom.

The company says the new C314X has a rated operating capacity that matches the diesel unit at 460 kg (~1014 lbs.) and a hinge pin height of 2.2 m (~7.2 ft.).

Though still “just a prototype” at this point, CASE and New Holland products have a history of making it to production. If when it does, company reps say it will be available in two undercarriage configurations, a “narrow track” version 890 mm wide that can fit through garden gates and man doors, and wide track version 1026 mm wide for heavier duty outdoor and agricultural work.

The stand-on machine uses controls that will be familiar to any mini loader operator — especially those with experience behind the controls of the diesel C314 — and all the implements and attachments that work on the diesel version bolt up to the C314X Electric, making it ideal (the company says) for livestock and horticultural farmers, landscape contractors and residential construction operations, thanks to multiple compatible attachments to ensure full versatility to dig, load, drill, and more.

Stay tuned for pricing and availability, likely set to be announced during ConExpo 2026.
