rad power bikes safe shield battery

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.

Segway’s feature-packed E3 Pro electric scooter with Apple Find My hits new $500 Black Friday low (Save $200)

Segway’s Black Friday Sale is in full gear and currently seeing hundreds in savings and plenty of returning and new low prices on its e-scooters and e-bikes. One such standout is Segway’s latest E3 Pro Electric Scooter down at $499.99 shipped, and which seems to have disappeared from Amazon’s marketplace. Carrying a $700 MSRP since launching back at the top of October, we’ve only seen this model given $100 price cuts in its launch deal and the brand’s Halloween and early Black Friday sales. Now, with things having ramped up with increased savings now that Black Friday is in full swing, you can score a larger-than-ever $200 markdown to a new all-time low price, giving you an advanced upgrade to your commute that I have been loving so far since getting one a short time ago.

I’ve been riding around Brooklyn for a short time now with my own Segway E3 Pro Electric Scooter and have been loving my experience so far, as it’s a MAJOR step up from the very basic E22 model I’ve had for short travels since 2020. While power has been significantly ramped up from its E2 Pro predecessor, this new generation still retains a fairly lightweight 40-pound design, which I am able (as a not-so-strong person) to carry easily with one hand/arm up and down my second-story stoop.

Segway’s E3 Pro comes bearing a 400W motor (with 800W peaking) alongside a 368Wh battery, the combination of which delivers up to 34 miles of commuting support for your travels at up to 20 MPH speeds. The regenerative brake paired with the brand’s SegRange Optimization tech really lends towards the extended travel times here, with safety taken into mind with the SegRide stability enhancement tech, the latest traction control system, turn signaling, RGB ambient lighting for nighttime journeys, and a bright headlight. What’s more, security is bolstered by the Apple Find My inclusion for those worried about tracking it down should theft (or forgetfulness) occur.

One thing I have really been enjoying, especially when riding over more pot-hole lined streets, is Segway’s E3 Pro’s dual elastomer suspension, which does a great job of smoothing out overall rides, while providing added cushioning when sudden, jolting sections of the road (or debris/trash) are driven over. Along with all those, there are also additional features, including the previously mentioned rear electronic regen brake getting a companion front drum brake, as well as 10-inch self-sealing jelly tires, an IPX5 water-resistant build, a 265-pound total payload, and a 3-inch full-color LED screen for setting adjustments.

Be sure to check out Segway’s full official Black Friday Sale while it lasts for a short while longer, which can save you hundreds at the best prices of the year starting from $150.

NIU’s Black Friday EV Sale is in full motion now, taking up to 47% off its lineup of e-scooters and e-bikes, like the KQi 200F Foldable Handlebar Electric Scooter for $529 shipped, which you can currently only find in a used condition at Amazon. This is one of the brand’s newer 2025 models that fetches $799 at full price, which dipped down to this rate for the first time earlier in the month before these Black Friday savings. Now, you’re getting another shot at this all-time low price with $270 savings, giving you a solid commuter that sits among the mid-range models from NIU.

Anker’s SOLIX C300X 90,000mAh portable power station + solar bundle option at new Black Friday lows from $160

As part of Amazon’s ongoing Black Friday Week Sale, and running parallel to Anker’s SOLIX Black Friday Sale, the brand’s official storefront is offering the C300X 90,000mAh Portable Power Station (misnamed on page as C200X) for $159.99 shipped. Normally going for $300 at full price, this alternate darker colorway beats out its standard grey colorway’s direct sale pricing by $40, with its Amazon pricing on that model also beaten out by the same amount. Discounts before October kept things above $189, with increased falls lower to 169 and $161 over last month and mid-way through this month, before this Black Friday deal dropped things to a new all-time low. Not only are you saving a total $140 here, but you’ll also be getting the best price tracked on the station’s 60W foldable solar panel bundle that’s down at a low of $240 shipped.

Tesla has sold ~100 cars since entering the world's largest country in July

tesla store how to test drive buy a tesla

Tesla’s much-awaited entry into the Indian market has resulted in very slow sales to start, but it may not all be bad.

We’ve covered the years-long effort of Tesla to enter the Indian auto market. There have been a lot of intentions and fits and starts, but due to protectionist schemes in the country it never made a lot of sense for Tesla to enter.

That changed this year in March, when India waived EV import duties, allowing foreign firms to bring their cars in for sale. While India does have some strong local brands in Mahindra and Tata, this opened the gates to Chinese, German, Korean and American brands – namely, Tesla.

So far, other American companies have declined to bring their EVs to India, but Tesla opened its first showroom in Mumbai, India’s most populous city and financial capital, in July of this year. It opened a larger “Tesla Center” showroom in Gurugram, outside Delhi, this week.

So, Tesla is only getting started in India, but by all measures it has been an exceedingly slow start, according to the BBC.

Dealership data shows that Tesla has only sold “just over” 100 cars in India since July, an exceedingly low number by any measure – especially when considering the India is now the most populous country in the world, with a population of just under 1.5 billion.

Tesla’s rocky start included losing its head of Indian operations just before launching its first store, among a slew of other executive departures this year and last.

The numbers look a little less bad when comparing against EV sales in the country. While India has sold an impressive 2 million electric vehicles this year, the vast majority of them have been electric scooters.

Electric passenger cars are a much lower share at around 160k total unit sales this year so far, making up only around 3% of the passenger car market. And the majority of those are lower-cost domestic brands Mahindra and Tata or a growing section of Chinese challengers, with very few sales from overseas luxury brands.

Tesla could be included in that “luxury brand” list, largely due to the price of its imported vehicles. While the Model Y starts at $40k in the US, that price rises to 5,989,000 Rupees in India (~$67k USD). This is simply an unaffordable price for the vast majority of Indians – indeed, only around 1% of India’s auto sales are in the “luxury” category.

Further, EV infrastructure is not very well developed in the country. Tesla has one Supercharger in India, and two listed as “coming soon” in the Gurugram area. There are thousands of other charging points across India (and of course, drivers can charge overnight at home), but the number is still relatively low compared to the country’s population.

Meanwhile, other brands’ EV sales are growing well in India. The auto market as a whole has grown by about 13% this year in the developing country, but EV car sales have grown by 57% in the same period, rapidly outpacing the auto industry as a whole.

Much of that sales growth has been driven by Chinese EVs, which make up around a third of the market. That’s around ~60k Chinese EVs sold this year in India.

Even luxury German EVs from Mercedes, BMW and Audi have sold around 4,000 units so far this year, not a large number, but certainly dwarfing Tesla’s.

So while it’s tempting to look at Tesla’s poor numbers and make excuses about the size of the EV market, ability of Indians to afford luxury vehicles, or state of India’s charging network, it’s hard to compare that low ~100 sales number at any of the competition and label it as anything other than an extremely poor showing.

But, you do have to start somewhere, and the company is only a few months in. So we’ll have to see where it goes from here – though with the sales we’ve seen so far in Mumbai, entering the Delhi market is unlikely to forestall Tesla’s current global sales decline.

The 30% federal solar tax credit is ending this year. If you’ve ever considered going solar, now’s the time to act.
