The first mass-produced 900V drive system rolled off the production line Wednesday. Chinese EV maker NIO’s (NIO) “Thunder” 900V electric drive system (EDS) can add over 150 miles (255 km) with five-minute fast charge.

NIO announced the milestone Wednesday after building its one-millionth EDS. NIO’s Porsche-rivaling ET9 premium EV will be the first to feature the new tech.

The ET9 was unveiled in December aimed at “the new generation of high-end business users.” NIO packed the luxury EV with its latest tech for a “perfect package of flagship-style exterior, spacious interior, immersive experience, efficient recharging.”

This includes the world’s first mass-produced 900V EV drive system with up to 925V, 600 kW peak power, and 765A peak charging.

NIO claims the electric motors in the front and rear are smaller and 30% lighter to improve efficiency. Meanwhile, the smaller units provide more interior space.

The ET9 will be the first to use a 925V W-Pin synchronous permanent magnet electric motor (340 kW peak power). At just 174 lbs (79 kg), the unit provides 4.3 kW/kg power density, which NIO claims is the highest among asynchronous induction EV motors. The front motor features 180 kW peak power with 2.6 kW/kg power density.

NIO’s new EDS also features a 1200V silicon carbide power module with 1315 kW/L power density. It can handle over 300,000 power cycles. The 900V EDS also boasts a liquid-cooling system that increases the motor’s peak continuous power by 20%.

NIO’s luxury ET9 EV is loaded with new tech

The ET9 will be integrated with over 100 NIO full-stack technologies. It will also feature NIO’s first five-nanometer auto-grade chip and large cylindrical battery cells.

NIO already opened ET9 pre-orders in China, with a starting price of $112,000 (800,000 yuan). It’s expected to rival luxury automakers like Porsche, BMW, and Mercedes-Benz.

At 5,325 mm (210″) long, 2,016 mm (79″) wide, and 1,620 mm (64″) tall, the ET9 will rival premium vehicles like the Porsche Panamera (205″ x 78″x 56″).

The ET9’s “Landjet” design opens up plenty of interior space with comfort, safety, and advanced tech. NIO filed 24 self-developed patents for the first-class rear seats alone.

With SkyRide active suspension, the ET9 includes independent control of all four wheels, enabling body adjustments like “shaking” shown in the video below.

NIO says the ET9 can be recharged in three minutes via battery swap or add 158 miles (255 m) with five-minute fast charging. Deliveries are expected to kick off in the first quarter of 2025.

The news comes as Chinese rival IM Motors revealed its new L6 EV will also utilize a 900V platform. According to IM Motors, it will include solid-state batteries with over 620 miles (1,000 km) range.

Why some Scrooges want to stop California from handing out $2,000 e-bike vouchers

Why some Scrooges want to stop California from handing out ,000 e-bike vouchers

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.

Check out this awesome looking new four-wheeled electric bike

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.
