It turns out cyclists actually should roll through stop signs. Here’s why
When it comes to greening up our transportation systems and reducing the massive carbon footprint left by our daily commutes, there’s a much better solution than trying to get everyone into an electric car. Encouraging increased cycling, whether on electric bikes or good old-fashioned acoustic bikes, has the biggest impact on reduced emissions and the health and well-being of our society. But with safety at the top of the list of concerns for those switching to a two-wheeled commute, more studies are showing that the best way to protect cyclists at the most dangerous point on their rides is to simply let them blow through stop signs in what is commonly known as an “Idaho stop”.
The Idaho stop gets its name from the state that first enacted it into law back in the 1980s. In an Idaho stop, cyclists are permitted to treat stop signs as yield signs, meaning they slow down and look for traffic before continuing through, no full stop required. In many states, the Idaho stop goes further, not just letting cyclists treat stop signs as yield signs but also treating red lights as stop signs.
There are few things more frustrating to anti-cyclist drivers than seeing a bike rider roll through a stop sign or red light (perhaps seeing them zip past traffic by using the bike lane could be one of them?), but studies are now showing that using an Idaho stop is actually safer than requiring cyclists to come to a full stop at stop signs.
As Alvin Holbrook pointed out in Velo, a recent study by the University of Oregon that put cyclists and drivers in over a dozen “live interaction” four-way intersection scenarios revealed results that may surprise some drivers.
The study found that cyclists preferred the Idaho stop method (which is pretty obvious for a vehicle that works largely by maintaining momentum), but also that when drivers received an education about the rolling stop sign law for cyclists, they approached intersections slower than before and created fewer dangerous scenarios for the cyclists.
Alvin explained, “The main takeaway from the study is that a rolling stop law allowed people biking to do an action they preferred in treating a stop sign as a yield. And once drivers were educated, intersection interactions between people biking and driving were no more dangerous than before introducing the law.”
In other words, safety increased instead of decreasing when an Idaho stop was permitted and when drivers were informed of the law.
That’s just one example, but many studies have confirmed the result that Idaho stops, or rolling stop laws, either increase the safety of road users or have no impact (i.e. are no more dangerous to cyclists than requiring a full stop).
Alvin also pointed to a study from Delaware, one of eight states in the US that has an Idaho stop law on the books, which found a 23% decrease in car/bike crashes at intersections after the Idaho stop law was enacted.
Another study performed in Tampa Bay, Florida, (a state infamous for its questionable drivers) and commissioned by the Florida Department of Transportation, “found that dangerous street design and motorists are what put cyclists at risk, not cyclist behavior.” That study found a nearly 90% traffic law compliance among cyclists, which might surprise drivers who tend to remember the few cases they witness of cyclists breaking traffic law, then projecting that onto all riders. But as the study shows, cyclists are generally incentivized to follow traffic law more than drivers since the risks of not doing so are higher.
The least flattering study on Idaho stops comes from Illinois, where the researchers found no difference in the proportion of crashes after the Idaho stop law was enacted. However, they did find that the severity of those crashes decreased. The result was that cyclists were able to move around more efficiently without increasing the rate of crashes and while decreasing serious crashes.
Even the National Highway and Traffic Safety Administration (NHTSA) highlights the fact that “there is no evidence showing bicyclist stop-as-yield laws have increased bike conflicts with other bikes or pedestrians.”
So why is it safer for cyclists to blow through stop signs or continue through a red light after stopping?
It likely comes down to a number of factors, but several of them lead back to the same underlying issue: intersections are the most dangerous location for cyclists since such intersections are designed for cars, not bikes. When stopped at an intersection, cyclists often disappear from the view of car drivers, blending into the background while drivers instinctively look for other cars. A moving bike is more visible to drivers due to millions of years of evolutionary pressure adapting humans to spot movement.
Rolling through stop signs also means cyclists ultimately spend less time in the most dangerous location for them, quickly moving out of intersections and back to the relative safety of bike lanes on straightaways.
And as studies show, cyclists generally don’t blow through stop signs in a dangerous fashion. They’re incentivized to slow down and check for traffic out of sheer self-preservation. They don’t have a 5,000 lb steel cocoon to protect them the way drivers do. This is despite there being a decent chance that the reader’s confirmation bias would argue differently, as it is easy to remember the last time we all saw a cyclist do something dangerous and forget the dozens of cyclists riding safely that we conveniently ignore every day.
But as Alvin points out, “The bottom line is every person on a bicycle has more to lose — and a greater incentive to yield — when entering an intersection than a driver does. A collision between a car and someone walking and biking will always be tilted against the person outside of the car.
Streets are safer when there is a common understanding of what to expect from everyone. Streets are safer when car drivers aren’t able to use stereotypes of cyclists breaking laws to threaten and harass them. And of course, streets are safer when people are biking.”
Kubota came to this year’s CES with a sprawling display filled with electric equipment, hydrogen gensets, and an onslaught of commercial robots ready to mow, farm, dig, and build. If you weren’t impressed by Kubota’s display this year, you weren’t paying attention.
Kubota gave us a sneak peek of its KATR farm robot – itself a smaller, updated version of last year’s New Agri Concept – before the doors officially opened last week. Kubota’s robotic farm buddies promise to be able to quietly and autonomously haul stuff from one end of the farm to another, or pull carts and specialized implements along predetermined paths.
KATR uses self-leveling technology and active suspension to ensure its cargo deck stays level when working on the sort of uneven terrain found on farms or construction sites.
That doesn’t mean the New Agri Concept is dead, though. Agri Concept 2.0 debuted as an electric tractor concept offering AI-powered automation and a fully electric powertrain. The new version features a Lite Brite-style “grille” that it uses to communicate its current mode, direction, and other important information with the people it shares a job site with.
On the more practical side, Kubota showed off its KX38-4e Electric compact excavator. First shown in overseas markets in 2022, the KX38-4e Electric features a 49.2 kWh lithium-ion battery that’s good for up to five hours of continuous operation. More than enough to complete a typical day of work on a construction site when you factor out idle time.
An onboard DC fast charger means it can be quickly recharged between shifts, too. But when there’s no grid power on the site, charging can be a challenge. That’s why Kubota has hydrogen genset for zero-emission on-site power generation.
Looked at individually, each of the new electric Kubota products on display might be impressive. The real magic, though, is in the way the Kubota machines work together as a holistic job site or farm solution.
“At Kubota, we believe that truly listening to our customers drives innovation in every aspect of what we call the ‘Work Loop’,” explains Brett McMickell, Chief Technology Officer of Kubota North America. “The Work Loop — an essential cycle of assessing, analyzing, and acting — has always been fundamental to effective task management. With the integration of advanced sensors, AI-driven analysis, networking protocols, automation, and robotics, we are enhancing this cycle to be more seamless and efficient than ever before.”
That was obvious in some of the more thoughtful implements and attachments on display, including a Smart Plant Imager that uses advanced robotics and “hyper-spectral imaging” cameras to capture real-time data and insights on a plant-by-plant level – as well as a Smart Autonomous Sprayer and Robotic Pruner that that classifies buds and canes based on position and fruiting potential, it optimizes production precision and accuracy.
The more you look, the more impressive Kubota’s farming solution gets. “We will continue to learn from many of our customers across segments to iterate the next product and technology solution that will help them manage tomorrow’s challenges and grow their businesses,” McMickell added. “This is how Kubota works to make a better quality of life for individuals and society.”
There was more, of course. Autonomous versions of the company’s electric zero-turn mower with GPS-powered route memory, fun accessory baskets for the robots, even a weird, jet engine looking thing that I forgot to ask about (below). I was genuinely impressed, in other words, and can’t wait to see what Kubota comes up with next year.

The e-bike industry has stalled a little bit in terms of features, and with harsh new legislation coming in from places like California, maybe it is time to start looking at e-bikes that are light, efficient, and smooth rather than how much wattage they can output. The Tenways CGO 600Pro, which comes in at just 37 pounds, is a model e-bike you should keep an eye on…
The CGO 600Pro comes in 2 flavors: a carbon belt single-speed version that Micah reviewed and this one, which is a chain and 8-speed Shimano gears. The belt drive is going to win out on simplicity and weight but if you are expecting to get close to the ‘class 1’ top speed of 20mph or need to go up some significant hills, you’ll want to opt for the chain/gear version here.
One thing I love about this bike is the tradeoff decisions. These keep the price low and weight down while still providing a great ride. The spec sheet overall is solid but not top-shelf.
Tenways CGO600 Pro tech specs (chain/geared version)
- Motor: 350 Watt rear hub motor with 45 Nm of torque
- Top speed: 20 mph (32 km/h)
- Range: Claimed up to 53 miles (85 km)
- Battery: 36V 10Ah (360 Wh)
- Weight: 37 lb (16.8 kg, over 40lbs with fenders, kickstand, etc)
- Frame: 6061 aluminum alloy
- Tires: CST Puncture-proof 700*45C-size Tires
- Brakes: Tektro dual-piston hydraulic disc brakes
- Gearing: Shimano 8-Speed Claris
- Extras: Compact LED display, 4 pedal assist levels, slim fender set, kickstand, internally routed cables, LED lighting, removable battery, Tenways app integration, torque sensor, four color options
No Throttle?
Note that as a class 1 e-bike, neither belt/chain version has a throttle. While this may be controversial to some, it not only simplifies the bike, it makes it a Class 1, which will be legal in the most places. I tend to think of no throttle as a “foot throttle” and for the commuter application, this will serve well. Would I appreciate a throttle on a hill start? Perhaps.
The idea of this bike is to just enhance your pedal bike experience. You are going to get some exercise on this bike versus a bike that is a glorified low-power moped that runs on throttle with vestigial pedals.
More importantly, the torque sensor here is phenomenal; I mean, it is probably the best torque sensor I’ve ridden connected to a rear hub motor. The acceleration is smooth and strangely powerful for the 350W/45nm motor. Significant hills are a breeze, and this is one of the few bikes where I forget that I’m using an e-bike sometimes (until I look down and I’m going 20mph with little effort). Hills are also where the gearing really helps.
The tires are also the perfect size for a commuter with puncture resistance and treads that will do OK in rain and snow.
The bike itself is also very stealthy in terms of showing that it is a powered e-bike. The small 36V, 10Ah battery is integrated magnificently into the narrow downtube of the bike. All of the cables are integrated into the bike frame for a super-clean look. The rear hub motor is small but packs a punch. Many people won’t even recognize this as an e-bike. While I’m proud to be riding an e-bike around, perhaps some people would like to keep that on the down-low.
Brakes are great with hydraulic Tektros clasping against 160mm rotors in front and back. It is such a light bike that stopping can be jarring.
Assembly was super easy and took about 30 minutes with the included tool set. The battery came about 40% charged but was ready to go within a few hours with the 3A charger. Shoutout to Tenways for using a water-resistant standardized barrel charger adapter and not some proprietary adapter so that I can use one from another bike when I inevitably lose it.
Electrek’s take
The Tenways CGO600 is a fantastic light, clean, stiff and smooth e-bike that I have 0 reservations about recommending. While the battery and motor are small, they power the light bike admirably and for around 50 miles (your mileage will vary).
Currently there is a $200 off promotion code “HAPPY2025TW” at checkout bringing the CGO600Pro down to $1399 which is an amazing price for this bike:

Earlier this month, California enacted new regulations for electric bikes that resulted in stricter speed limits on e-bikes with throttles. At the time, it was unclear how electric bike makers would respond to the new regulations, but we’re now starting to see at least one manufacturer pushing to bring its existing e-bikes owned by California residents into compliance.
The new laws remove ambiguity in the Class 2/Class 3 e-bike categorization. Formerly, many e-bikes were designed to operate in either category depending on the owner’s desires. Such bikes could operate as Class 2 e-bikes reaching max speeds of 20 mph (32 km/h) with a throttle, or as Class 3 e-bikes reaching higher speeds of 28 mph (45 km/h) on pedal assist-only.
In fact, the overwhelming majority of Class 3 e-bikes sold in the US used this design, offering hybrid compliance for functionality as both Class 2 and Class 3 e-bikes.
After California’s new laws removed any ambiguity between the classes, it is now clear that e-bikes in the state will need to function either only as Class 2 e-bikes (throttle up to 20 mph) OR Class 3 e-bikes (up to 28 mph but without any throttle).
It was unclear whether existing e-bikes already sold prior to the law’s enactment would receive an exemption, but bicycle manufacturer Specialized doesn’t seem to be taking any chances.
Specialized is the maker of the Globe line of cargo e-bikes, and recently sent out an update to owners that would help them bring their e-bikes into compliance with California’s new stricter regulations.
Like so many other electric bikes on the market, the Globe e-bikes came with throttles allowing 20 mph speeds without pedaling, but could also reach up to 28 mph on pedal assist.
A new firmware update promoted by the company will essentially restrict its e-bikes to purely Class 2 operation, removing the motor’s ability to assist the bike in going any faster, even when pedaling without throttle operation.
The update will also come with a Class 2 compliance sticker that replaces the previous Class 3 sticker.
To install the voluntary update, Globe owners are encouraged to visit their local Specialized dealer.
A copy of the update letter was shared on Reddit and can be seen below.
Electrek’s Take
This is an interesting approach, because it indicates an understanding by Specialized that it is responsible for any of its e-bikes already on the road that have now been made non-compliant by the new law.
There are basically two main options to “fix” these previously hybrid Class 2/3 e-bikes and bring them into compliance. One is to unplug and remove the throttle, turning the bike into a true Class 3 e-bike under CA regulations. The other is to remove the ability for the motor to assist at speeds over 20 mph, turning it into a Class 2 e-bike. That latter is what Specialized appears to have decided to go with, and it makes sense to me. If you asked most owners of these e-bikes about which they’d give up if they had to, they’d probably tell you “take my 21-28 mph speed but leave me my throttle”. Throttles are simply such a major part of e-bikes in North America that most riders would give up the whole bike if they were forced to give up the throttle.
The bigger question here is how many Globe riders will actually install this update. Since you need to not only opt-in to it, but also physically visit a dealer to do it, I have to imagine that the vast majority of riders will simply ignore the update altogether, keeping their faster non-compliant speed on an e-bike with a throttle. I’m not saying that’s the right thing to do, but I am saying it’s what will happen in the real world.
And if we are being honest, these Globes aren’t even the e-bikes that are at the heart of the issue. Most CA residents are more concerned with teenagers ripping down sidewalks on moped-style e-bikes, not the local moms and dads riding to Trader Joe’s on their sensible, upscale cargo e-bikes that just happen to have hybrid Class 2/3 performance.
