Zero FXE electric motorcycle ridden by Micah Toll

Electric motorcycles are my jam. If I’m on two wheels and it’s not a bicycle, then odds are I’m on an electric motorcycle. I don’t ride them because they’re clean or green, though those are nice side benefits – I ride them because they’re fun and enjoyable. They’re infinitely better than sitting in a car watching the world go by through glass. And the ownership experience is so much nicer than gas motorcycles due to their greatly reduced maintenance, lower cost of ownership, lack of vibrating cacophony, and a laundry list of other reasons.

My love of these awesome e-motos has put me in a unique position of having ridden pretty much every one of them out there.

Now let me stop the pedants right here for a second. No, the title isn’t clickbait.

But to say it in more words than fit in a headline, I’ve ridden basically every electric motorcycle out there, not counting a few cool international models I’m still missing (Stark Varg, TS Bravo, etc.) and a few super low-volume boutique e-motorcycle companies in the US (Tarform, Lightning, etc.).

But other than those few edge cases, I’ve ridden every major electric motorcycle currently available in the US, and some that aren’t even available yet.

Here’s a rundown of what you need to know about each company, the cool bikes they build, and how they ride. And since I could never possibly cover each one in enough nitty-gritty detail in a single compilation article like this, make sure you click through to the in-depth reviews I’ve done on these bikes as well.

To avoid playing favorites, I’m also going to bang these out in alphabetical order. Sorry, Zero, but that’s on you guys.

My first experience on the Arcimoto FUV and Roadster

Arcimoto

You might not even think of Arcimoto’s FUV (which stands for Fun Utility Vehicle) to be a motorcycle, but that’s what these electric three-wheelers are considered in most places. Some jurisdictions call them autocycles, but they’re mostly three-wheeled motorcycles.

And just like the name implies, they’re super fun to ride.

They have some idiosyncrasies, mind you. There’s no power steering, and so they feel pretty heavy to steer at low speeds, but they’re a blast at any speed. With a pair of bucket seats, they basically feel like 75 mph electric go-karts. They’re quite powerful, though they’ll never beat something like a Zero or a LiveWire off the line. Even so, they’ll get you up to 75 mph quickly, and they actually feel quite good at speed.

One of the best parts is also just how many looks and comments you get. The last time I was riding one was in San Francisco when I attended the Micromobility America 2022 conference. People were stopping me on street corners just to ask about these wild-looking things. Another experience near Miami was the same thing – people were riding up next to me on the street just to talk about it.

I also like how they have a locking trunk in back and how the rear seat can also be used for a decent amount of cargo space (when you’re not carrying a passenger).

The range is modest at around 100 miles in city conditions, but highway riding cuts that range down quickly. Don’t expect to go on long touring rides with these.

I’ve also tested the open-top Arcimoto Roadster, which feels more like a trike motorcycle. Its chopped top and sportier seating position give an entirely different sensation. It’s a lot of fun, but I prefer the FUV for daily riding.

Neither are the most practical vehicles on the road. They’re too wide to lane split but too small for carpool duty. But they make up for it in sheer charm.

The only other slight downside is that you’ve got to think about your placement on the road as a triple-track vehicle. Unlike a motorcycle, where you swerve around obstacles or a car where you straddle obstacles, triple-track vehicles like these trikes mean you have to be more accurate when “threading the needle” with potholes, road debris, etc. If this were your daily driver, then I’m sure you’d get used to it quickly. But each time I hop back in one, I have to remember that I’ve not only got three wheels on the ground, but each one follows a different line.

CAKE

CAKE has three main platforms: the Kalk electric dirt bike, the Ösa electric utility bike, and the Makka electric moped. To be fair, I’ve only tested the first two, and it wasn’t a particularly long test ride on either, but they were both quite enjoyable.

The Kalk is their original dirt bike-style electric motorbike. It introduced the brand’s Swedish design with a love-it-or-hate-it appearance and showed that CAKE was here to play with the big boys. You’ll regularly see CAKE Kalks flying through the air and taking big jumps in stride.

The bikes are powerful, fairly lightweight, and a lot of fun to ride, though they’re pretty pricey at around $14,000.

The lower cost INK line drops the price by a couple thousand bucks, but these still aren’t budget bikes. Fortunately, they do have both on- and off-road versions of the Kalk line, meaning you can actually use them as street-legal motorcycles too.

cake osa electric motorcycle — A CAKE Ösa electric motorcycle

The CAKE Ösa is a utility bike that was first marketed as a “workbench on wheels.” That feels like a suitable name for these things. They are incredibly modular and are designed to be customized based on your needs. Whether that’s delivering packages, powering an electric saw for a carpentry job, or working as a forest ranger and carrying around axes and chainsaws, they’ve been outfitted for just about everything.

They’re also quite powerful and fun to ride. I was having a bit too much fun with one in a gravel lot in Munich, leading to one of my only motorcycle crashes from getting a bit too jubilant in the corners.

Of all the powerful e-motos out there, who crashes a CAKE Ösa?

CAKE’s rides are awesome-looking and fun-riding electric motorcycles, but they don’t have the same bang-for-buck you’d get elsewhere. You’re paying for fancy Swedish design, which is still worth something, but it means these won’t be the best option if you’re trying to squeeze every penny. For those that want something different looking though, CAKE takes the cake.

CSC

CSC is a California-based motorcycle importer that deals with largely Chinese-made bikes, both ICE and electric. They’ve got some of the best prices in the business, and they only work with good-quality imports. They also have an absolutely massive warehouse in LA that is stocked to the brim with dozens of spares of every part on all of their bikes, which ensures that you get US-level service if you ever need a spare part. I’ve tested all of their electric motorcycles, but my sister has their CSC SG250, and the head mechanic at CSC even walked us through a carb tuning question over the phone while we worked on the bike. So don’t think that just because these are Chinese bikes means you’ll get bad quality or poor service. You get good versions of both.

Now let’s get to the bikes. The most impressive in the lineup is the CSC RX1E. I rode one near LA, and it was so much more impressive than I was expecting.

It’s got a super comfortable adventure bike setup, even though it’s really more of an urban commuter. But with a liquid-cooled motor, top speed of 80 mph (130 km/h), and a range of 112 miles (180 km), it can handle any commute you can throw at it. At its current price of $8,495, it gets you similar performance to an entry-level Zero motorcycle but at a fraction of the price.

CSC City Slicker. I wish I had my Dianese jacket on when I crashed that CAKE Osa above…

A much smaller bike in the company’s lineup is the CSC City Slicker, which is more like a Honda Grom-sized electric motorcycle. It has a lower top speed of 45 mph (72 km/h) and is definitely meant for sticking to the city, hence the name.

The removable battery makes it convenient for charging in an apartment, yet it still gives you all the motorcycle fun of flying around turns while trying to drag knee. It may have scooter-level performance, but it comes in a motorcycle-shaped package. When riding the City Slicker, I would always get questions from people and thumbs-ups along the way. There’s just something about a mini-moto that makes people look up.

Speaking of scooters, the CSC Wiz has much of the City Slicker’s performance but in a true scooter platform. That means you get a cargo trunk, a step-through body for even more cargo space at your feet, and a big comfortable seat with plenty of room for a second rider. As long as you are OK with speeds in the low 40’s of mph, then the Wiz is a great, low-cost electric scooter option at just $2,495.

Last but not least, you’ve got to check out the CSC Monterey. At just $2,195, this vintage Honda Cub-inspired scooter looks incredible. It’s underpowered and only gets up to 32 mph (51.5 km/h), but it makes up for the lackluster performance in pure charm.

I got a Monterey, and everywhere I went, people would smile and give me a thumbs-up. When I parked, people inevitably want to ask me about it. It’s a crowd-pleaser for sure. I ultimately gave it to my father, who gets a kick out of the classic styling. It also goes nicely in his retro-themed garage. If you live in a beach community or other area with lower-speed roads where a 32 mph scooter will suffice, the CSC Monterey is a hoot to ride.

Energica

Wow, Energica’s bikes are some of the most powerful motorcycles I’ve ever ridden. I’ve been on three of the models, including the Ribelle, EsseEsse9, and the new Energica Experia.

That’s actually the order I tested them, and each one gets better and better, at least in my opinion.

Micah Toll on Energica Ribelle electric motorcycle — Energica Ribelle

I’m more of a comfort cruiser type of rider than a super-tucked sport rider, and so while the Ribelle is fun, that streetfighter is sportier than I really need. The EsseEsse9 was my favorite with its lower pegs and higher bars, even if the bike has slightly less power than the Ribelle.

But when Energica launched the Experia, that bike quickly became my favorite of the bunch. The sport tourer combined a powerful drivetrain with a comfortable and upright seating position. And with level 3 DC fast charging, touring is a reality with quick charge stops while grabbing a coffee or a bite to eat.

The Experia is my hands-down favorite of the bunch, but any time I get a chance to hop on an Energica, I know I’m going to have a good day.

My first ride on an Energica Experia in the Italian Alps

I was on the Ribelle for a couple of days on a recent trip to San Francisco and had a blast on the bike. While going over the windy bridges, I was glad to be on a solid, heavy bike as opposed to something much smaller.

So while I’d definitely opt for the Experia if it were me, the company’s sportier bikes are still a blast. The only model I haven’t tried is the Evo, which is just so much sportier than I’d ever need or want. But those who have them seem to love them, so to each their own!

Gogoro

Gogoro technically isn’t available in the US… yet. But since the company is rapidly expanding its presence, I’ll include Gogoro just in case they decide to come stateside soon.

The company recently expanded to Tel Aviv, Israel. For those who don’t know, despite being in the US often to ride new bikes and enjoy the country’s vast diversity of riding areas, I actually live in Tel Aviv most of the year. And so I was one of the first to get a new Gogoro S2 ABS electric scooter when they came out.

gogoro electric motorbike with Micah Toll

The scooters use a pair of swappable batteries that are the heart of the Gogoro Network. I’ve never charged the scooter – I’ve only ever swapped batteries. Theoretically, the range is well over 100 km (62 miles) in the city, but I’m often taking it up to its top speed of 95 km/h (59 mph) on highways, and so I often get closer to 60-70 km of range (36-45 miles).

But there’s a battery swap station every mile or two in Tel Aviv, and so range just isn’t an issue. When the batteries start to get low, I just roll into a battery swap station and pop in a pair of freshly charged batteries. The whole thing takes barely a minute if I’m moving slowly, and I can get it done in 30 seconds if I’m quick. A monthly subscription of around $38 covers my access to the swap stations.

‘Repowering’ era for America’s aging wind energy industry begins, despite Trump’s effort to kill it

'Repowering' era for America's aging wind energy industry begins, despite Trump's effort to kill it

On Inauguration Day, President Donald Trump issued an executive order indefinitely halting permits for new onshore wind energy projects on federal land, as well as new leases for offshore wind farms in U.S. coastal waters. The action not only fulfilled Trump’s “no new windmills” campaign pledge, but struck yet another blow to the wind industry, which has been hit hard over the past few years by supply chain snags, price increases upending project economics, public opposition and political backlash against federal tax credits, especially those spurring the fledgling offshore wind sector.

Nonetheless, the nation’s well-established onshore wind industry, built out over several decades, is generating nearly 11% of America’s electricity, making it the largest source of renewable energy and at times last year exceeding coal-fired generation. On April 8, the fossil-fuels-friendly Trump administration took measures to bolster coal mining and power plants, but as the infrastructure driving wind energy ages, efforts to “repower” it are creating new business opportunities for the industry’s key players.

This repowering activity has emerged as a bright spot for the wind industry, giving a much-needed boost to market leaders GE Vernova, Vestas and Siemens Gamesa, a subsidiary of Munich-based Siemens Energy. Following several challenging years of lackluster performance — due in particular to setbacks in both onshore and offshore projects — all three companies reported revenue increases in 2024, and both GE Vernova and Siemens stock have moved higher.

GE Vernova, spun off from General Electric a year ago, led overall onshore wind installations in 2024, with 56% of the U.S. market, followed by Denmark’s Vestas (40%) and Siemens Gamesa (4%).

GE Vernova stock performance over the past one-year period.

According to the U.S. Energy Information Administration, installed wind power generating capacity grew from 2.4 gigawatts (GW) in 2000 to 150.1 GW as of April 2024. Although the growth rate for launching new greenfield onshore wind farms has slowed over the last 10 years, the U.S. is still poised to surpass 160 GW of wind capacity in 2025, according to a new report from energy research firm Wood Mackenzie.

There currently are about 1,500 onshore wind farms — on which more than 75,600 turbines are spinning — across 45 states, led by Texas, Iowa, Oklahoma, Illinois and Kansas. Virtually all of the wind farms are located on private land, and many of the largest ones are owned and operated by major energy companies, including NextEra Energy, RWE Clean Energy, Pattern Energy, Clearway Energy, Xcel Energy and Berkshire Hathaway‘s MidAmerican Energy, which generates 59% of it renewable energy from wind, including 3,500 turbines operating across 38 wind projects in Iowa.

A growing number of the turbines are 20-plus years old and nearing the end of their lifecycle. So increasingly, operators have to decide whether to upgrade or replace aging turbines’ key components, such as blades, rotors and electronics, or dismantle them altogether and erect new, technologically advanced and far more efficient models that can increase electricity output by up to 50%.

“What’s becoming clear is that more and more of the U.S. installed base [of onshore turbines] has exceeded its operational design life,” said Charles Coppins, research analyst for global wind at Wood Mackenzie, “and now operators are looking to replace those aging turbines with the latest [ones].”

To date, approximately 70 GW of onshore wind capacity has been fully repowered in the U.S., according to Wood Mackenzie, while an additional 12 GW has been partially repowered. The firm estimates that around 10,000 turbines have been decommissioned and that another 6,000 will be retired in the next 10 years, Coppins said.

Beyond the fact that aged-out turbines need to be upgraded or replaced, repowering an existing wind farm versus building a new site presents economic benefits to operators and OEMs. To begin with, there’s no need to acquire property. In fact, in certain situations, because today’s turbines are larger and more efficient, fewer turbines are needed. And they’ll generate additional electricity and have longer lifecycles, ultimately delivering higher output at a lower cost.

Even so, “there are some limitations on how much capacity you could increase a project by without having to go through new permitting processes or interconnection queues” to the power grid, said Stephen Maldonado, Wood Mackenzie’s U.S. onshore analyst. As long as the operator is not surpassing the allowed interconnection volume agreed to with the local utility, they can add electricity to the project and still send it to the grid.

Public opposition, Maldonado said, may be another hurdle to get over. Whether it’s a new or repower wind project, residents have expressed concerns about environmental hazards, decreased property values, aesthetics and general anti-renewables sentiment.

RWE, a subsidiary of Germany’s RWE Group, is the third largest renewable energy company in the U.S., owning and operating 41 utility-scale wind farms, according to its CEO Andrew Flanagan, making up 48% of its total installed operating portfolio and generating capacity, which also includes solar and battery storage.

One of RWE’s two repower projects underway (both are in Texas), is its Forest Creek wind farm, originally commissioned in 2006 and featuring 54 Siemens Gamesa turbines. The project will replace them with 45 new GE Vernova turbines that will extend the wind farm’s life by another 30 years once it goes back online later this year. Simultaneously, RWE and GE Vernova are partnering on a new wind farm, immediately adjacent to Forest Creek, adding another 64 turbines to the complex. When complete, RWE will deliver a total of 308 MW of wind energy to the region’s homes and businesses.

Flanagan noted that the combined projects are related to increased electricity demands from the area’s oil and gas production. “It’s great to see our wind generation drive the all-of-the-above energy approach,” he said. What’s more, at its peak, the repower project alone will employ 250 construction workers and over its operating period bring in $30 million in local tax revenue, he added.

In turn, the twin projects will support advanced manufacturing jobs at GE Vernova’s Pensacola, Florida, facility, as well as advancing the OEM’s repower business. In January, the company announced that in 2024 it received orders to repower more than 1 GW of wind turbines in the U.S.

Siemens Gamesa has executed several large U.S. repowering projects, notably MidAmerican’s expansive Rolling Hills wind farm in Iowa, which went online in 2011. In 2019, the company replaced 193 older turbines with 163 higher-capacity models produced at its manufacturing plants in Iowa and Kansas.

Last year, Siemens Gamesa began repowering RWE’s 17-year-old Champion Wind, a 127-MW wind farm in West Texas. The company is upgrading 41 of its turbines with new blades and nacelles (the housing at the top of the tower containing critical electrical components) and adding six new turbines.

In early April, Clearway announced an agreement with Vestas to repower its Mount Storm Wind farm in Grant County, West Virginia. The project will include removing the site’s 132 existing turbines and replacing them with 78 new models. The repower will result in an 85% increase in Mount Storm’s overall electricity generation while using 40% fewer turbines.

Preparing for ‘megatons’ of turbine recycling and tariffs

Another benefit of repowering is invigorating the nascent industry that’s recycling megatons of components from decommissioned turbines, including blades, steel, copper and aluminum. Most of today’s operational turbines are 85% to 95% recyclable, and OEMs are designing 100% recyclable models.

While the majority of mothballed blades, made from fiberglass and carbon fiber, have historically ended up in landfills, several startups have developed technologies recycle them. Carbon Rivers, for example, contracts with the turbine OEMs and wind farm operators to recover glass fiber, carbon fiber and resin systems from decommissioned blades to produce new composites and resins used for next-generation turbine blades, marine vessels, composite concrete and auto parts.

Veolia North America, a subsidiary of the French company Veolia Group, reconstitutes shredded blades and other composite materials into a fuel it then sells to cement manufacturers as a replacement for coal, sand and clay. Veolia has processed approximately 6,500 wind blades at a facility in Missouri, and expanded its processing capabilities to meet demand, according to David Araujo, Veolia’s general manager of engineered fuels.

Trump’s new-project moratorium isn’t his only impediment to the wind industry. The president’s seesaw of import tariffs, especially the 25% levy on steel and aluminum, is impacting U.S. manufacturers across most sectors.

The onshore wind industry, however, “has done a really good job of reducing geopolitical risks,” said John Hensley, senior vice president for markets and policy analysis at the American Clean Power Association, a trade group representing the clean energy industry. He cited a manufacturing base in the U.S. that includes hundreds of plants producing parts and components for turbines. Although some materials are imported, the investment in domestic manufacturing “provides some risk mitigation to these tariffs,” he said.

Amidst the headwinds, the onshore wind industry is trying to stay focused on the role that repowering can play in meeting the nation’s exponentially growing demand for electricity. “We’re expecting a 35% to 50% increase between now and 2040, which is just incredible,” Hensley said. “It’s like adding a new Louisiana to the grid every year for 15 years.”

GE Vernova CEO Scott Strazik recently told CNBC’s Jim Cramer that the growth of the U.S.’s electric load is the largest since the industrial boom that followed the end of the second world war. “You’ve got to go back to 1945 and the end of World War II, that’s the infrastructure buildout that we’re going to have,” he said.

As OEMs and wind farm developers continue to face rising capital costs for new projects, as well as a Trump administration averse to clean energy industries, “repowering offers a pathway for delivering more electrons to the grid in a way that sidesteps or at least minimizes some of the challenges associated with all these issues,” Hensley said.

ABB is bringing its new, 1.2 MW modular truck chargers to ACT Expo

Capable of delivering up to 1,200 kW of power to get electric commercial trucks back on the road in minutes, the new ABB MCS1200 Megawatt Charging System is part of an ecosystem of electric vehicle supply equipment (EVSE) that ABB’s bringing to this year’s ACT Expo.

ABB E-mobility is using the annual clean trucking conference to showcase the expansion of its EVSE portfolio with three all-new charger families: the field-upgradable A200/300 All-in-One chargers, the MCS1200 Megawatt Charging System for heavy-duty vehicles shown (above), and the ChargeDock Dispenser for flexible depot charging.

The company said its new product platform was built by applying a computer system-style domain separation to charger design, fundamentally improving subsystem development and creating a clear path forward for site and system expansion. In other words, ABB is selling a system with both future-proofing and enhanced dependability baked in.

“We have built a system by logically separating a charger into four distinct subsystems … each functioning as an independent subsystem,” explains Michael Halbherr, CEO of ABB E-mobility. “Unlike conventional chargers, where a user interface failure can disable the entire system, our architecture ensures charging continues even if the screen or payment system encounters issues. Moreover, we can improve each subsystem at its own pace without having to change the entire system.”

The parts of ABB’s new EVSE portfolio that have been made public so far have already been recognized for design excellence, with the A400 winning the iF Gold Award and both the A400 and C50 receiving Red Dot Design Awards.

New ABB chargers seem pretty, good

ABB says the systemic separation of its EVSE enhances both reliability and quality, while making deployed chargers easier to diagnose and repair, in less time. Each of the chargers’ subsystems can be tested, diagnosed, and replaced independently, allowing for quick on-site repairs and update cycles tailored to the speed of each systems’ innovation. The result is 99% uptime and a more future-proof product.

“The EV charging landscape is evolving beyond point products for specific use cases,” continued Halbherr. “By implementing this modular approach with the majority of our R&D focused on modular platforms rather than one-off products … it reduces supply chain risks, while accelerating development cycles and enabling deeper collaboration with critical suppliers.”

Key markets ABB is chasing

HVC 360 Charge Dock Dispenser depot deployment; via ABB.

PUBLIC CHARGING – with the award winning A400 being the optimal fit for high power charging from highway corridors to urban locations, the latest additions to the A-Series All-in-One chargers offer a field-upgradable architecture allowing operators to start with the A200 (200kW) with the option to upgrade to 300kW or 400kW as demand grows. This approach offers scalability and protects customer investment, leading to Total Cost of Ownership (TCO) savings over 10 years.
PUBLIC TRANSIT AND FLEET – the new Charge Dock Dispenser – in combination with the already in market available HVC 360 – simplifies depot charging with a versatile solution that supports pantograph-, roof-, and pedestal charging options with up to 360kW of shared power and 150m/490 ft installation flexibility between cabinet and dispensers. The dispenser maintains up to 500A output.
HEAVY TRUCKS – building the matching charging infrastructure for commercial vehicles and fleets represents a critical innovation frontier on our journey to electrify transportation. Following extensive collaboration with industry-leading truck OEMs, the MCS1200 Megawatt Charging System delivers up to 1,200kW of continuous power — 20% more energy transfer than 1MW systems — providing heavy-duty vehicles with purpose-built single-outlet design for the energy they need during mandatory driver breaks. To support other use cases, such as CCS truck charging, a dual CCS and MCS option will also be available.
RETAIL – the award winning C50 Compact Charger complements the family as the slimmest charger in its category at just 9.3 inches depth, optimized for convenient charging during typical one-hour retail experiences. With its large touch display, the C50 takes the award-winning A400 experience even further — setting a new standard for consumer experience and very neatly echoing our own take on that “Goldilocks” timing zone for commercial charging.

ABB says that the result of its new approach are chargers that offer 99% plus uptime — a crucial statistic for commercial charging operations and a key factor to ensuring customer satisfaction. The new ABB E-mobility EVSE product family will be on display for the first time at the Advanced Clean Transportation Expo (ACT Expo) in Anaheim, California next week, then again at Power2Drive in Munich, Germany, from May 7-9.

Electrek’s Take

The ACT Expo is one of – if not the most important sustainable trucking event in North America, featuring all the big names in heavy trucks, construction equipment, material handling, infrastructure – even Tier 1 suppliers. Mostly, though, it’s many fleet buyers’ only chance to test drive these zero emission trucks before writing a big PO (which just makes it even more important).

Whisper Aero ultralight aircraft scores $500K for “UltraQuiet” electric jet motor tests

Whisper Aero ultralight aircraft scores 0K for

Whisper's "UltraQuiet" propulsion system to power acrobatic glider

Along with Tennessee Tech, Tennessee-based ultralight aircraft company Whisper Aero has secured a $500,000 grant to help advance the company’s innovative electric jet motor concept off the drawing board and onto the testing phase.

Earlier this month, the Tennessee Department of Economic and Community Development (TNECD) announced plans to award $500,000 to Tennessee Tech and Whisper Aero through the Transportation Network Growth Opportunity (TNGO) initiative.

“We look forward to using these award dollars to place students in internships working directly with Whisper Aero leaders,” said Tennessee Tech President Phil Oldham. “By learning from an electric propulsion innovator like Whisper Aero, our students will gain invaluable perspective and can take what they have learned in the classroom and apply it right here in Tennessee.”

The grant will see a Whisper Aero glider fitted with a pair of the company’s eQ250 electric-powered jet “propulsors” for UltraQuiet flight. Tennessee Tech faculty and students will carry out copper-bird ground testing to ensure the safe integration of engines, batteries, and controllers, and kickstart Tennessee Tech’s new Crossville Mobility Incubator.

Those propulsors, by the way, are super cool.

UnltraQuiet WhisperDrive; via Whisper Aero.

Whisper Aero’s main claim to fame is its innovative UltraQuiet WhisperDrive (above). It’s effectively an electrically spun ducted fan jet engine that uses a large number of stiff composite fan blades inside a lightweight, acoustically treated duct. With so many blades, the Whisper Aero propulsor can push more air than a conventional prop while spinning much more slowly. As such, the “blade passage frequency” moves up to more than 16,000 Hz – outside the range of most human hearing but not, supposedly, high enough to freak out the beagles.

The Whisper Aero ultralight is effectively an Aériane Swift3 glider fitted with a pair of Whisper’s eQ250 propulsors, each capable of up to 80 lbs. of thrust. The Ultralight has a wingspan of over 40 ft with a maximum L/D of 35:1 and can be stressed to a design loading of +6/-4g, making it capable of some pretty impressive acrobatic feats.

The Swift3 glider is designed for a low speed, low power cruising speed of 45–55 knots with “just” 6.5 hp. Power-off glides from a few hundred feet showed a low sink rate, and a climb rate of 1,250 ft/min with full self-launching power (in other words: the Whisper glider doesn’t have to be towed by a launch vehicle, like a conventional ultralight glider).

Quiet cool

Dual WhisperDrive fans deliver ~160 lbf of thrust; via Whisper Aero.

Range under full power is about 109 miles with current battery tech, but it’s expected that range under the latest EPiC 2.0 energy batteries would rise to nearly 170 miles.

Nathan Millecam, CEO of Electric Power System, said, “EPiC 2.0’s leap in energy density and thermal performance has enabled a significant increase in range, a clear validation of our next-gen cell technology. We are impressed by what the Whisper team continues to achieve in advancing electric aviation.”

The press release concludes explaining that flight tests are expected to show that the Whisper Aero glider can be flown, “a few hundred feet away from neighborhoods without any disturbances, while carrying a 220 lbs. payload with full range,” which is all kind of ominous in today’s political climate, but still pretty neat from a purely tech perspective.

The TNGO grant follows a separate grant from NASA awarded last year, though that grant aims to develop the eQ250s – not as a propulsion system, but as a key component in future spacecraft ventilation systems.
