The AMD Ryzen Threadripper 1950X and 1920X Review: CPUs on Steroids

In the early 2000s, we had the battle to high frequencies. The company that could force the most cycles through a processor could get a base performance advantage over the other, and it led to some rather hot chips, with the certain architectures being dropped for something that scaled better. Move on 10-15 years and we are now at the heart of the Core Wars: how many CPU cores with high IPC can you fit into a consumer processor? Up to today, the answer was 10, but now AMD is pushing the barrier to 16 with its new Threadripper processors. We got both of the launch CPUs for review and put them on the grill.

Henrik Fisker interview: the EMotion EV, and a ‘game-changer’ charging method

In Torrance, Calif., a Danish-born designer-cum-CEO is putting his own name behind a car company he’s building. It’s not the first time

Henrik Fisker

has done this, but perhaps it’ll go a little more smoothly this time around. The timing seems better for what he wants to do, which is launch a high-end, long-range

electric vehicle

.

It’s not settled where

Fisker

will build its first car, the $129,900

EMotion EV

, yet. The company is looking to buy an existing factory but hasn’t chosen one yet. Henrik Fisker tells us they’ve looked at a few, but with no hint of pressure in his voice, says, “We don’t have to make a decision until the end of the year.” Fisker expects to begin producing the EMotion in 2019.

FISKER EMOTION: THE BASICS

The Fisker EMotion is powered by two electric motors, one in the front and one in back, giving it all-wheel drive. Fisker told us the EMotion has “a new type of electric motor that we are working on together with a very large supplier.” He said it’s efficient, light, and compact, but declined to offer up other details, including output. That announcement will come later.

In terms of aerodynamics, Fisker says there’s a limit to what you can do and still make the vehicle look nice. “You can make a pretty

ugly car

that’s very aerodynamic. You probably remember the

GM

EV1 that was super aerodynamic, but not necessarily a very pretty car. The Fisker brand is about good-looking cars.”

Fisker says, though, that there are aero benefits that an electric powertrain makes possible. He was able to lower the front of the EMotion, which he says really makes this four-door look evolved compared to the traditional sedan. With no gasoline engine up front, that lowered cowl also improves the view of the road ahead. Because of its electric layout, The EMotion is able to have its wheels at the very corners, with minimal front and rear overhang. The car features what Fisker calls a “very, very dramatic” functional rear diffuser, which takes advantage of the EV’s flat underside. The EMotion also has a small integrated rear spoiler, and airflow around the wheels was optimized without disrupting the car’s sculptural look.

With the EMotion, Fisker wants to blend sport with luxury. Again, thanks to the packaging of the electric powertrain, the company is able to create a roomy interior by pushing the windshield forward and the rear window back. Fisker even goes so far as to compare the rear legroom to that of a

BMW

7 Series. We’ll have to wait for full interior details, as Fisker plans to make further announcements later in the year (which is hard to imagine, looking at the EMotion’s exterior, until you notice how far back the rear doors are placed in comparison with the rear wheels).

With more people living and using cars in big cities, low-speed comfort is becoming more important. Fisker intends to deliver on that with the EMotion. As we spend more time driving in a different environment than we did 10 or 20 years ago, Fisker told us, “We have to emphasize in different things [than just driving dynamics] how to have fun driving a vehicle. Part of that will be a whole different interface in our vehicle, which we are working on in-house, to create more excitement, more entertainment.” He adds, “In autonomous driving, specifically in stop-and-go traffic, you need to have something else to do.” The car should also be fun to drive, and because EVs are so quiet, Fisker is working on ways to “engage the senses” while driving.

The car should also be quick and handle well, especially at $129,900. Other automakers have already proven EVs can be fast, and Fisker is also working on handling. The EMotion’s all-wheel drive and low center of gravity (thanks to the battery pack) improve the car’s handling. He says the EMotion’s carbon fiber rims are 40 percent lighter than aluminum wheels, and the body uses carbon fiber as well, to help make the car light and quick.

ENERGY

The Fisker EMotion’s lithium-ion battery pack is uses 21700 cylindrical cells from

LG Chem

with NCM (nickel-cobalt-manganese) cathode chemistry. To keep the actual physical volume of the battery down, Fisker has created its own cooling system that helps increase energy density. Fisker says the battery pack will offer the highest energy density in the world. The 21 modules that make up the pack sit extremely low in the vehicle. Their thin profile helped Fisker take advantage of the space inside the vehicle, providing that roominess we discussed earlier.

There won’t be a variety of battery options in the Fisker EMotion. Every car, beginning with the $129,900 base model, will come with the same UltraPack, offering over 400 miles of driving range. “At least the plan at this point is not to offer it with a smaller battery pack. We really want to show this as the ultimate

electric car

.”

Even if people don’t normally drive 400 miles in a day, range is important to the consumer. Fisker asked, why aren’t more people buying electric vehicles? He identified range and charging time as two key solutions that would get more people into EVs. The EMotion’s 400-plus-mile range should take care of range anxiety, allowing more flexibility to travel longer distances or to own EVs in places where infrastructure is limited (and to make people feel like they aren’t giving something up by switching to an EV). That second part of the equation — charging — is where things get really interesting.

Fisker’s not happy with the idea of stopping at a destination, such as a mall, where it takes an hour or so to charge (assuming there’s a charging point available). Instead, Fisker envisions a new standard of chargers, which he calls “Ultrachargers,” located at

gas stations

. He tells us his company is in talks with big oil companies to install these Ultrachargers at their retail locations. While the Fisker EMotion will be an expensive vehicle, it’s this charging technology that he thinks will eventually get the masses into EVs. But what is it?

“We are working on this new charging, which is a different type of charging. It’s not a cable, and it’s not inductive charging. We can’t really reveal it yet — we’re working on prototypes right now — ­but I think this could be a new standard where you actually don’t even have to get out of the car to charge the vehicle.”

Boy, did our ears perk up at that. Without getting into too much detail, Henrik Fisker told us that his company is working on prototypes for this new type of charger with ABB, a European provider of fast charging infrastructure. The EMotion will still be able to use the same types of charging stations we have today (it will use the CCS charging standard), “but we also want to launch it with this new type of charger, which we think is pretty exciting,” Fisker said, “and a game-changer.”

AUTONOMOUS DRIVING

Interestingly, Henrik Fisker downplayed the idea of autonomous driving during our conversation, despite the fact that the EMotion makes use this technology.

Fisker doesn’t think customers are all that interested in sitting and doing other activities while doing 70 miles per hour on an open road. It’s the stop-and-go traffic that’s frustrating, and that’s the problem autonomous driving capabilities help to solve. “That’s when probably most people are tending to start playing with your entertainment system or picking up your phone. So, we are really looking at that space to be able to truly take your hands off the steering wheel and do something else.”

Not being able to take your hands off the steering wheel when you have autonomous capability, Fisker says, is “like having a passport, but you can’t leave the country.” Fisker thinks it makes the most sense in terms of safety to offer hands-free driving at low speeds, specifically in a traffic jam on the freeway, where there aren’t any pedestrians and any accident would have milder consequences. Like the rest of us, he’s unsure how the legislation surrounding self-driving cars will shake out, so he’s not leaning too heavily on that aspect of the vehicle to sell it.

SERVICE AND DISTRIBUTION

Fisker has

announced a partnership

with

The Hybrid Shop

— which Fisker says will be called “The EV and Hybrid Shop” –— which will service the EMotion. Currently, there are 36 Hybrid Shops. At the launch of the EMotion, Fisker said he expects there to be about 250 in the U.S. Fisker wants to revolutionize that facet of ownership, though, and make it as seamless as possible.


“You can do a lot of stuff over the air, but eventually there are tires that are going to need to be changed, or something’s going to happen with the car that needs service,” Fisker said. “When that happens, we have a predictive service where basically the car’s fully connected with The Hybrid Shop infrastructure.” So when something goes wrong, or is about to go wrong, the owner doesn’t have to do anything. The car is connected to your calendar, and knows when you won’t be using it. It will send you a notification suggesting a pickup time for you to approve. After that, technicians can pick up your car while you’re at work using a digital key, service it, and return it to you before the end of the work day.

This is meant to make it easier to live with the car. Fisker says this new service model and self-parking are the best solutions for people who live in big cities ­— the same people who are more likely to put off

buying a car

because of the inconvenience.

When a customer buys a Fisker EMotion, either online or at one of the company’s planned “Experience Centers,” those same Hybrid Shop service centers will be the ones who prepare and deliver the

new vehicle

. Customers will be able to take a virtual or real test drive, spec and order their car, and a “concierge” will deliver it to them at their home or workplace with everything ready to go, down to installing the customer’s various preferences in the interfaces.

LOOKING DOWN THE ROAD

Fisker learned from his last venture and is applying that knowledge to this new one. He tells us that the EMotion will be a lower-volume vehicle, and that making use of advanced, lightweight materials like carbon fiber and aluminum and the like means a lower investment in tooling. “Of course,” Fisker said, “it also means the car will be more expensive.” He said he wants to use this car to showcase the company’s technology, so that it can return later with “a higher-volume vehicle for a much lower cost.”

Fisker wouldn’t tell us what that next vehicle would be, but he said it would be on a different platform from the EMotion. “We have a very clear idea what the next car will be,” he said, “but we don’t want to say it yet. But it will be a very affordable vehicle.” The costs of batteries and electrical components are a challenge, but he’s encouraged by what LG Chem is doing in that regard.

Fisker believes, though, that solid-state is the future of batteries. His company is working on graphene and solid state technology, and already has patents. He’s not sure when that tech will be ready for commercialization, but it won’t be in time for the EMotion, and probably past 2022 or 2023, he said. “At that point in time, the electric car will be fully superior to a gasoline car in any aspect — price, performance, everything.”

Of course, Fisker

isn’t the only one

who believes solid state batteries are the future.

Toyota

,

Kia

, and others are working on this technology as well. “I personally feel like we might be one of the ones that are furthest along. We have a great battery chemistry team, and that’s something that’s kind of unusual, but I really decided that that’s one of the areas where we want to spend a lot of effort in-house.” Researching and developing battery chemistry, modules, and charging are important to tackle in-house, “because those are the things we have to solve to make the electric car mass-market and superior to a gasoline car.”

Henrik Fisker believes that 10 years down the road, EVs will achieve about 20 percent market penetration in the U.S., and more than that in the parts of the world that do more to promote electrification. That’s why he’s happy to be starting anew with an all-electric vehicle. He wishes

Karma Automotive

luck with the Revero, but says, “I obviously wanted to move forward and do what I feel is innovative and something for the future.” He adds, “When we started the

Fisker Karma

way back, at that time, the battery technology was still not where we wanted it to be, which is why we chose a

plug-in hybrid

. I think today we are now far enough that we can get, like I say, that range that at least I would want. I think battery electric cars will be the future.”

And because the number of cars on the road is going to increase, they need to be environmentally friendly, Fisker said. Carsharing, ride-hailing,

autonomous vehicles

, these all transfer usage from public transportation ro smaller vehicles with fewer people in them (but on a more direct route). “We will probably have even more driven miles in the future than we have today,” Fisker said. And a lot of those miles will be in cars, whether we’re the ones controlling them or not.

That’s why electric cars are increasingly necessary for a clean environment. “But I also think,” Fisker said, “that electric cars need to be fun and cool and desirable.” And that’s where Fisker Inc. sees itself. The company wants to “make a cleaner environment, but [do] it while having fun. We’ll let other people make the boring cars, because I’m sure they’re going to be there as well.”

WHAT ABOUT VLF AUTOMOTIVE?

Fisker thinks about

VLF

as a “hobby shop,” or a “kid’s dream.” He told us, “We no aspirations of being a giant car company or anything. It’s kind of three guys —

Bob Lutz

, and Gilbert [Villarreal], and myself — having fun. We don’t have any marketing department, you know. We just make the car we think will be cool, and we hope somebody’s going to buy it.

He sees the VLF product — low-volume, high-performance, internal-combustion

supercars

— as “almost like a mechanical watch that nobody really needs anymore, but they’re still fun and cool.”

“I actually think that in the future, the boring gasoline cars are going to be unnecessary, because you might as well be driven, or drive an electric car when you do your daily commute. But, just like it’s fun to have a mechanical watch, it still will be fun to have a

sports car

where you really interact with the mechanics of the vehicle, and you may only do it on the weekend, for fun. And that’s kind of what we do at VLF.”

“It’s like when you go out and just have a steak without even a salad.”

AMERICA FIRST

Henrik Fisker left us with some parting words at the end of our conversation. He told us he believes that “America is leading in electric vehicle development,” and points to startups in California as evidence of that. “Once the electric car takes off in the mass market, we want America to be the leader in that, because that’s going to be the most important technology going forward.”

Tesla developing self-driving tech for semi-truck, wants to test in Nevada

Tesla

Inc is developing a long-haul, electric semi-truck that can drive itself and move in “platoons” that automatically follow a lead vehicle, and is getting closer to testing a prototype, according to an email discussion of potential road tests between the car company and the Nevada Department of Motor Vehicles (

DMV

), seen by Reuters.

Meanwhile, California officials are meeting with Tesla on Wednesday “to talk about Tesla’s efforts with autonomous trucks,” state DMV spokeswoman Jessica Gonzalez told Reuters.

The correspondence and meeting show that Tesla is putting self-driving technology into the electric truck it has said it plans to unveil in September, and is advancing toward real-life tests, potentially moving it forward in a highly competitive area of commercial transport also being pursued by

Uber

Technologies Inc and Alphabet Inc’s Waymo.

After announcing intentions a year ago to produce a heavy-duty electric truck, Musk tweeted in April that the semi-truck would be revealed in September, and repeated that commitment at the company’s annual shareholder meeting in June, but he has never mentioned any autonomous-driving capabilities. Tesla has been a leader in developing self-driving technology for its

luxury cars

, including the lower-priced Model 3, which it is beginning to manufacture.

Several Silicon Valley companies developing autonomous driving technology are working on long-haul trucks. They see the industry as a prime early market for the technology, citing the relatively consistent speeds and little cross-traffic trucks face on interstate highways and the benefits of allowing drivers to rest while trucks travel.

Some companies also are working on technology for “platooning,” a driving formation where trucks follow one another closely. If trucks at the back of the formation were able to automatically follow a lead vehicle, that could cut the need for drivers.

Silicon Valley startup Peloton Technology, for example, is working with several truck makers including

Volvo

on its platooning system, which it sees as a precursor to autonomy.

Tesla’s high-flying shares, up almost 70 percent this year, closed down 0.5 percent at $363.53 on Nasdaq, but rose slightly after hours.

An email exchange in May and June between Tesla and Nevada DMV representatives included an agenda for a June 16 meeting, along with the Nevada Department of Transportation, to discuss testing of two prototype trucks in Nevada, according to the exchange seen by Reuters.

“To

insure

we are on the same page, our primary goal is the ability to operate our prototype test trucks in a continuous manner across the state line and within the States of Nevada and California in a platooning and/or Autonomous mode without having a person in the vehicle,” Tesla regulatory official Nasser Zamani wrote to Nevada DMV official April Sanborn. He made no reference to any dates for potential road tests.

No companies yet have tested self-driving trucks in Nevada without a person in the cab. On July 10, Zamani inquired further to the Nevada DMV about terms for a testing license, an email seen by Reuters shows.

California DMV spokeswoman Gonzalez said that Tesla had requested a meeting on Wednesday to introduce new staff and talk about Tesla’s efforts with autonomous trucks. She said that the DMV was not aware of the level of autonomy in the trucks.

Tesla declined to comment on the matter, referring Reuters to the previous statements by Musk, who has discussed the truck in tweets and at the annual shareholder meeting.

Nevada officials confirmed the meeting with Tesla had occurred and said that Tesla had not applied for a license so far. They declined to comment further.

Musk has said that potential customers are eager to get a Tesla electric long-haul truck, but he faces doubt that the company can deliver.

While established trucking companies and truck manufacturing startups have poured resources into electrifying local package delivery fleets, battery range limitations have largely kept the industry from making electric trucks that travel across swaths of the country.

Lithium ion battery researcher Venkat Viswanathan of Carnegie Mellon University said electric long-haul trucking is not economically feasible yet.

“Your cargo essentially becomes the battery,” Viswanathan said of the massive batteries that would be needed to make range competitive with

diesel

.

Diesel trucks used for cross-country hauls by United Parcel Service Inc can travel up to 500 miles (800 km) on a single tank, according to UPS’s director of maintenance and engineering, international operations, Scott Phillippi. By comparison, the company’s electric local package

delivery trucks

travel up to 80 miles on a full charge.

How art could help encourage kids to study science

Mixing art and science started very early for Kari Byron. “I remember distinctly sitting there with a Cheerio box and a roll of tape, and trying to recreate a human skull, like a little sculpture,” she says, recalling her earliest memory of tinkering with something in her childhood.

That fascination never went away. Byron is most well known for her science-facing roles as a member of the build team on Mythbusters, and her recent role in Netflix’s The White Rabbit Project, but she has been a creator for as long as she can remember. Trained in film and sculpture, but with over a decade of experience diving head-first into wacky televised experiments, Byron also embodies a recent push towards STEAM education.

STEAM includes arts in the traditional STEM cluster of science, technology, engineering and math. The move is controversial to many in both STEM and arts fields for distracting from the primary purposes of each discipline, whether it be the master of technical knowledge or divergent thinking and self-expression. Mixing the stereotypically “intuitive” with the “analytical” disciplines challenges conventional knowledge that the people have an aptitude for one or the other. But Byron, influenced from a young age by unconventional figures such as Ada Lovelace, has always believed in the happy marriage of the two. What she thinks is really important is getting kids excited about exploring their curiosity.

We hear a lot about STEM education being a key factor in spurring innovation and driving the national economy. But while the science and technology job market is increasing three times faster than the rest of the economy, U.S. enrollment in STEM undergraduate degrees is lower than in many other industrialized countries. The discrepancy between market demand and labor supply leaves many people worried about our ability to fill those jobs, and continue creating innovative technologies. Obama made STEM a priority under his administration, but limited interest in science, engineering, and technology amongst United States youth remains a concern.

In recent years some educators like the President of the Rhode Island School of Design and Mae Jemison (the first black woman in space) have embraced art under the umbrella of STEM. Pulling from historical examples of artist-scientists like Leonardo da Vinci, and contemporary examples like the beautiful designs of Apple technology, these advocates argue that art and science are deeply related, and we should be teaching them together. Entertainment groups like the Blue Man group and Sesame Street have also found value in bringing the two classically separate fields together. Byron is no exception, being of the perspective that, “Science is a creative field, it’s just more organized.” For her, science and art have always had a shared core of curiosity, creativity, and experimentation.

What Byron emphasizes is how infectiously exciting that core of curiosity can be. “When you take your creativity and you throw your energy into it, it almost works like a drop in a pond, it radiates outward, and creativity begets other creativity.” And in a moment when schools are criticized for not fostering creativity, perhaps the key to getting more students to pursue scientific and technical fields is by focusing on brainstorming and simply building things. Project-based learning at the intersection of STEM and art is a great way to engage kids this way through diving in with a “no wrong answers” attitude.

Byron said, “In my own personal journey, when I started to approach science like art, and get my hands messy, that’s when I started to love it.” After all, what does it matter if it’s called science or art, as long as kids are excited about it and learn something? Projects like building a camera from scratch and taking photographs, and working with 3D printers can fall into both categories comfortably.

Crucial to sustaining that infectious creativity is what Byron calls the ability to “Crash and Learn.” In simple terms, it’s the ability to learn from your mistakes, and it’s something Byron seems to have learned the hard way, “With Mythbusters, that was our daily business. We were given problems that were beyond my general knowledge, so we had to get things wrong over and over and over again.” She recalls a time when she had to build a flying guillotine, “I failed over and over and over and over, but I had so much fun in the mix, trying to come up with the right thing, was all part of the process. I feel like I learned so much about mechanics just from trying to create this gruesome device, that they just stayed with me. That was my class that day. Learning just how to do it.”

Although being able to “Crash and Learn” might seem obvious to those with experience in technical fields, for a lot of students it’s the very hardest thing to learn. The same message about learning to tolerate failure has circulated with under the names grit with educational psychologists, and bravery by the CEO of Girls Who Code. Being able to keep going after you fail is something that’s hard for many people. Byron’s solution? “If you’re excited about it, they’ll be excited about it. You’re the very best role model they can have just by being excited yourself. You don’t have to teach them anything, you just gotta get in there and do it,” she says. In other words, shared excitement can be the silver bullet that gets kids through the tougher moments of failure during experimentation.

Byron believes that whether it’s learning about the chemistry of color in paint, or the how to design a social robot to look friendly—STEAM might be exactly the movement schools need to bring students the raw joy of building, experimenting, and discovering science that defies expectations. She hopes that the new approach could help kids “crash and learn” their way to becoming the next generation of scientists. Byron’s latest projects bring together the artistic and scientific—like her most recent work with 4-H and their Incredible Wearables project for National Science Day. That’s where you’ll find Byron working to get kids just as thrilled about building as she was with that first cardboard skull. “When they see you getting excited about art and science,” she says, “it becomes part of their being, and they’re going to take that with them.”

General Motors employees get free self-driving car rides

Self-driving cars are already the primary mode of transportation for a small group in San Francisco.

Cruise, the self-driving arm of General Motors, has launched a private app for employees to request a free self-driving ride almost anywhere in the city.

The app, “Cruise Anywhere,” is available to 10% of the company’s more than 200 San Francisco-based employees. Cruise plans to expand the initiative to more employees soon.

Cruise’s test fleet of Chevy Bolts run 16 hours each day around most of San Francisco and has already given more than a 1,000 rides. A test driver is present to oversee the vehicle’s operation and guarantee safety.

Rides are requested on demand, similar to ridesharing services Uber and Lyft.

cruise automation 4

The move is a part of an effort to test and learn from operating its own ride service. The company hasn’t officially decided whether to deliver rides through its own app, or partner with another company.

Related: Lyft changes gears, decides to build self-driving tech

Cruise is among a handful of companies racing to deliver self-driving technology to consumers. Its rival Waymo, the self-driving entity of Google’s parent company, is launching a program in Phoenix to gives rides to the public. NuTonomy, another competitor, gives self-driving rides in Singapore.

Here’s Proof That Commuter Bikes Don’t Have to Suck

The perfect city bike would be comfy and safe to ride and it would look sharp. Bonus points if it’s super-low maintenance and doesn’t require you to constantly fiddle with the chain and the shifters.

Such bikes exist, but not if you’re on a budget. Bikes quickly get pricey once you start adding features that make them lighter, safer, and less fussy.

But I’ve got some good news: I think I’ve found the ideal city bike. The Priority Continuum Onyx offers all the features you want in an urban commuter, from disc brakes and fenders to a no-maintenance drivetrain, and the company brings it in at just under $1,000.

OK, $1,000 is still pretty steep, but you get a bevy of advanced features for your money. Priority offers so many city-friendly upgrades, in fact, that the price ends up being a real bargain.

The Continuum sports disc brakes, which provide greater stopping power than traditional caliper brakes—especially in the rain. You also get a Gates carbon belt instead of a chain. A belt drive offers greater durability and less mess, too. No need to worry about rolling in to work with a grease splotch on the cuff of your Levis.

Spin Control

But the thing that really stands out is the NuVinci Nfinity N330 hub. Within that metal shell at the center of the back wheel lies a CVT, or a continuously variable transmission. There are no discrete gears in a CVT, just a steady and smooth transition from the slowest, least efficient setting to the fastest, most efficient. It’s a lot like the transmission Subaru, Nissan, and others put in their cars. Now you can get one in your bike too.

To shift, just twist the grip-shifter on the handlebar and watch the little orange guy on the display next to your wrist. When he’s on the flats, you’re in high gear. When he’s struggling uphill, you’re in low gear. But it’s important to note you won’t find any “gears” in NuVinci’s CVT. If you want to compare the N330 to a traditional drivetrain, it gives you about the same gearing range as an 8-speed bike.

CVT hubs are starting to show up in other city bikes, and in bikeshare fleets in San Francisco and in New York. Their reliability and bomb-proof construction make them a good match for fleet bikes, which take no end of abuse. Imagine how much trauma those bikeshare hubs endure and you see the appeal of having one on your bike.

Roll With It

Put all of these great components—disc brakes, belt drive, the NuVinci hub—together and you’re typically looking at a bike closer to $2,000. But Priority keeps the Continuum Onyx relatively affordable by sourcing inexpensive but decent parts from Asia and selling directly to consumers online. Skipping the bike shop means you assemble your ride yourself, but Priority includes tools and instructions in the box. I found it no harder than wrangling a piece of Swedish flat-pack furniture. It took me 30 minutes to assemble the bike Priority sent me.

The Continuum Onyx is Priority’s top-of-the-line bike. The New York company also makes leisure models that cost between $400 and $800, but the Continuum Onyx is the one best suited to daily commuting. It includes fenders, the super-reflective decals and tires light up like Roman candles in in traffic, and the a headlight draws power from a Dynohub that generates electricity when the front wheel spins.

It’s nice to see quality city bikes getting cheaper even as they get better. It means there are more bike commuters on the roads, for one. More importantly, it makes people think of cycling not as something you do on weekends, but something you can do every day.
