Weeks after introducing a potentially game-changing “Uni-wheel” drive system for EVs, Hyundai and Kia are showing off another next-generation technology to keep EV drivers safer during inclement weather. Today, Kia and Hyundai introduced a new snow chain-integrated tire that utilizes shape memory alloy modules inside the wheel. See how this incredible new tech works in the video below.
As EVs continue to saturate the global automotive market, their respective technologies are evolving to benefit consumers. Now more than ever, these electric vehicles drive farther, charge faster, and come equipped with exciting new technologies like vehicle-to-load (V2L) capabilities and Plug & Charge.
Hyundai Motor Group has been one of the early proponents of such technologies, featuring them in EVs atop its E-GMP platform. In fact, Hyundai and Kia especially have rolled out some exciting technologies throughout the electric mobility segment and allocated considerable funds to R&D to explore new engineering breakthroughs.
Last month, the Korean automotive conglomerate introduced a new “Uni Wheel” system, described as a potential “paradigm shift” in drivetrain configurations. Traditional ICE vehicles utilize CV joints, but moving them closer to the wheels requires a short drive train length and, as a result, a decrease in efficiency and durability – especially over bumpy terrain. Hyundai and Kia’s Uni Wheel system, on the other hand, can transmit power with almost zero changes to efficiency, regardless of wheel movement.
The last breakthrough was met with some confusion as to how it worked, but once you watched the video, it garnered a lot of hype as a breakthrough technology. Today, Hyundai Motor Group has shared another exciting video about tires it has developed with alloy “snow chains” built in. Check it out.
Snow problem! Hyundai’s new tires come well equipped
As if Hyundai and Kia EVs weren’t already exploring the bleeding edge of efficiency, the automakers have developed a new tire/wheel combination that alleviates the need to haul around and install snow tires – a common practice for drivers in wintery regions that trek up mountains.
Hyundai explains that this new tire technology can automatically deploy shape memory alloy at the push of a button in the cabin, quickly offering EV drivers a snow chain-like grip during wintery road conditions.
This snow chain-integrated tire technology consists of a wheel and tire assembly consisting of radial, evenly spaced grooves that house modules made from shape memory alloy that can be deployed when an electric current is applied and can return to its natural shape inside the tire.
The video below showcases how it works best, but this could be a potential game-changer for snow tires if and when Hyundai and Kia integrate it into passenger EV models. When that may happen remains to be seen, but Hyundai appears to be working toward that goal. The automaker’s head of the advanced chassis development team, Joon Mo Park, elaborated:
This innovation, which will hopefully be introduced on Hyundai and Kia vehicles someday, reflects our commitment to turning advanced technologies into real-world solutions that benefit customers. We will continue to develop technologies that enhance safety and convenience of our vehicles and bring value to our customers.
Like the Uni-Wheel drive system mentioned above, Hyundai and Kia’s snow chain tires offer plenty of room for excitement about what technologies are yet to emerge within EVs, as long as their creators find a way to scale and integrate the technology as planned. While we wait for that, check out Hyundai Motor Group’s video explaining the new snow tire technology below:

In what couldn’t have been more on-the-nose timing, a group of local California newspapers published an editorial on Christmas Eve calling for the end of a generous $2,000 voucher program intended to help low-income Californians afford electric bicycles for transportation.
The editorial was provided by the Southern California News Group, a collection of California newspapers owned by the hedge fund Alden Global Capital.
In it, the writers air a number of grievances against the program, which recently closed its first round of applications intended to provide around 1,500 e-bike vouchers of between US $1,750 to $2,000 each. The vouchers can be used to offset the price of electric bicycles and associated gear such as protective equipment, locks, etc.
The first complaint in the op-ed is that the total number of vouchers provided in the first round was relatively small compared to the large size of the California e-bike market. However, instead of suggesting that the budget be increased to help more Californians achieve transportation independence, as we called for recently, the editorial takes the opposite position of suggesting that the program simply be canceled.
Next, the writers bemoan an increase in electric bicycle and electric scooter accidents in recent years, suggesting that this should be weighed against the benefits of helping more Californians afford such vehicles.
However, the argument seems to conveniently overlook the fact that the vast majority of such accidents aren’t caused by e-bike riders, but rather those riders are in fact usually the victims. The actual danger to safety on roads is vehicular traffic, i.e. cars and trucks.
Furthermore, many studies have shown that in crashes caused by e-bike riders, such as when an e-bike rider hits another cyclist or pedestrian, the injuries are on average considerably lighter and more recoverable than in car-related crashes.
If the goal was to protect Californians, then instead of firmly clutching their pearls, perhaps the editorial writers should have urged a reduction in the use of cars and trucks, not a reduction in e-bike vouchers.
The op-ed even goes on to lament the number of children riding electric bicycles in California, though admits further on that children aren’t eligible to receive vouchers as part of California’s e-bike incentive program.
Electrek’s Take
California’s e-bike incentive program is certainly far from perfect. We even discussed many of its shortcomings last week. But the program’s essence is to do a good thing—using public tax money to benefit the public. The solution should be to improve the program, not to remove it. And the simple fact of the matter is that most people who are vehemently against the program are those who don’t directly benefit from it, even if they fail to realize that they will ultimately indirectly benefit.
Electric bicycles are one of the most cost-effective ways to provide transportation independence to marginalized and low-income groups. But it’s more than just that. They’re also the best way to get people out of cars and reduce traffic for everyone. Even ignoring the long-term environmental effects related to reducing the impacts of climate change, e-bikes are uniquely capable of making a larger impact on air quality today by helping to remove sources of emissions from a vehicle’s production all the way through its lifetime use and even to its eventual disposal/recycling. When someone rides an e-bike instead of taking a car, taxi, or bus, everyone’s lungs benefit.
Sure, the California program isn’t perfect. But if a media group owned by a wealthy hedgefund and catering to a well-to-do readership doesn’t like it, then that means it’s probably doing something helpful to people who actually need it. That’s the kind of world I want to live in, at least for as long as it’s still liveable.

Sixthreezero’s wide range of electric bike models includes some fairly out-there models, but the company’s new four-wheeled electric bike really charts a new direction in the industry. Take a look at the new ANYterrain Stabilized 4-wheel Electric Bike.
It’s a mouthful of a name, but the ANYterrain Stabilized 4-wheel Electric Bike hauls more than just a bunch of extra words. The bike is rated to carry up to 350 lb (159 kg), and the 750W motor ensures it has the power to do so. With speeds of up to 20 mph (32 km/h), the quad bike is just as fast as most Class 1 and 2 e-bikes.
But the real game changer here is the design, offering four-wheeled stability that riders can’t get from a conventional three-wheeled trike.
Not only do four wheels provide better stability with a wider footprint, but the steering on the bike uses leaning geometry to take turns more naturally, helping riders feel even more stable.
With 20″ wheels in the rear and 16″ wheels in the front, the quad bike keeps a fairly low center of gravity. All four wheels use 4″ fat tires for better offroad riding and more comfortable shock absorption compared to narrow tires, and the rear wheels even feature a differential to better apply the motor’s power to the ground.
A twist throttle makes it easy to roll on that power, and a D/R switch on the bars lets riders put it in reverse for cases where they need a little help wiggling around in tight spaces. Pedaling backward from a stop can also engage the reverse. At 120 lbs (54 kg), this isn’t the type of bike you can just pick up and move around the garage without a little help so that reverse feature will likely come in handy.
A 48V and 20Ah battery offers 960Wh of capacity, which the company says translates into a range of up to 50 miles (80 km).
The battery is housed under a cargo basket in the rear, though a bench seat can be swapped for the basket, allowing riders to carry a passenger with them.
Electrek’s Take
This certainly won’t be a mass market type of e-bike, but I can see a real use case for neighborhood riding and local errands, especially for folks who don’t feel stable on a bicycle or even a trike.
Despite trikes offering great stability when going straight, some people can feel uncomfortable making turns on a trike, especially at higher speeds, because they can sometimes feel tippy under certain scenarios. This quad bike can still tip if you take a turn sharp enough, but the wider stance combined with the leaning steering means riders will even more stable than on a trike.
And since this will likely be used more by older riders, the reverse is an important feature for letting folks park the bike easily without dismounting and dragging it around.
There could be some legal hurdles in some areas that define “bicycles” as having either two or three wheels, but I’m guessing most cops aren’t jumping at the opportunity to ticket grandma for riding her quad bike on the local rails to trails network.
I love seeing more options like this, and I commend Sixthreezero for providing such interesting options to add to the market.
