The cyclist community needs to double-down on education and avoid compulsion. Gentle encouragement for helmets and lights, and setting an example, will have better results than advocating for mandates. Even though nearly everyone here understands that helmets and lights are a good idea; countering the false narrative of people like Frank is important but in a nice way. Passing out lights for free to those without them, whatever the reason someone lacks them, is one productive effort that I've engaged in, using my discretionary money when I was the mayor of my city. Several organizations offer free helmets, at least for children. Note that the "education" alluded to by SMS seems to be teaching people to use add-on gimmicks. There's no mention of teaching people the actual causes of crashes, nor the riding behaviors that minimize crashing. -- - Frank Krygowski |

The only time I notice a bicyclist with a headlight or tail-light on during the day is if they are in deep shade or if it's heavy overcast. The VAST MAJORITY of bicyclists do NOT repeat, do NOT, need a DRL. Agreed! Also, if cyclists ride more prominently in the lane, they're even less likely to not be noticed by motorists. The problem is, when people who buy a DRL get noticed, they say "Oh, he noticed me because of my DRL" even if they would have been noticed anyway. Confirmation bias in action. But I have seen situations where a DRL was noticeable. The other day we were driving back from Bangkok and because of the holiday traffic started very early in the morning - sun just peeping over the horizon - and met a bloke on a bicycle and yes the DRL did make him much more noticeable. As I've said, you can sometimes spot a bicyclist farther away because of a DRL. But I've never observed an incident when the DRL made a _practical_ difference. A cyclist doesn't need to be seen at the horizon. I have. Twice. Each time it was cyclist riding the wrong way on the side of the street. Both times were very early in the morning and if he had some sort of light I would have seen him further enough away to have easily avoided him rather then an "OH MY GOD" situation. In my state, lights are required from sunset to sunrise. That's actually a bit more strict than the law was a few years ago, when lights were required from half an hour past sunset to half an hour before sunrise. (Not that the laws are adequately enforced, mind you.) DRLs are lights in use outside those times, or outside similar conditions. If you're talking about "very early in the morning," so early that the cyclist was not visible, he may well have been in violation of the law. But that's a separate issue from "DRLs always for safety!" Frank, whether or not the two bikes that I almost hit may or may not been in violation of the law is meaningless, at least to me. But, really, does that make a difference? Laying there with the broken leg does one really feel better knowing that the guy what done it broke the law? As for DRL's I did research the subject and I find studies dating back to the 1970's and which showed that the use of DRL's did reduce the frequency of vehicle accidents, although the level of decrease did vary from study to study. But, perhaps more to the point you blithely ignore the fact that a number of studied of bicycle accidents have shown that, in some cases more than 50% of the accidents are the fault of the cyclist. Wouldn't it be more productive, rather then rant and rave about DRL's, to advocate riding a bicycle safely? Taking your response from bottom to top: I have certainly NOT ignored that half of bike crashes are cyclists' fault. I've agreed many times. That's one reason I'm such a proponent of cycling education. About DRL studies: I'm aware of only one that applies to bicyclists, and it was ludicrously biased. As evidence of bias, its data claimed the DRLs reduced even solo bike crashes. I don't believe motor vehicle DRL studies have much applicability to bike crashes. And about the personal incidents you alluded to: I'm strongly in favor of headlights and taillights during darkness or other low visibility conditions. That's the pertinence of your crashes being caused by illegal behavior, rather than lack of a _Daytime_ Running Light. -- - Frank Krygowski |

I would love a dyno light with a solid 800 lumen output, a little more upward spew and a stand light that was stronger than the light on my give-away key chain from Wells Fargo -- and one with a battery so I could use the light off the bike. We transportational cyclists often need a light for use off the bike. A flasher would be nice for dusk and dawn, but not required. And while we're wishing, how about something lighter and more efficient than a bunch of magnets whirling around. There must be some other way of harvesting electrons. Such a light would be wonderful but it would be a stretch with a 6V/3W dynamo, even at higher speeds where you can get more than 3 watts out of it. Some LED makers are claiming 300 lumens per watt, at least in the lab, but 200-250 lumens per watt are what is available commercially at this time. A 12V/6W hub dynamo (or even a 9V/4.5W hub dynamo) would make dynamo lights with sufficient intensity more practical, including a beam pattern where some upward spew would be possible. DRL flash capability is trivial to add, as are internal batteries to be able to use it off the bicycle. But there is just not much of a market for any of this.. You seem to have it stuck in your head that the internal impedance of a hub generator is some immutable quantity and not a design parameter. Why not a 6V/12W hub dynamo? Hell, if you were willing to do frequency dependent series capacitor switching, you can get a lot more than 3W out of a 3W labelled hub. Not stuck at all. The problem with that approach, and it's already been done via lowering the impedance by putting two bulbs (or LEDs) in series is that you don't reach sufficient power at lower speeds. OK. First off, putting two LEDs in series raises the impedance, and it works by allowing the voltage from the generator to go up. If you had a bit of intelligent electronics (a frequency sensor with some hysteresis), you could short out the second LED at low speeds where there isn’t enough voltage to drive two in series. Back in the days I experimented with halogen dyno lamps, I had two wired in series with a switch that would short either one or the other for low speed work, but have both in series at higher speeds. Series being the electricity goes first to one LED and then to the second LED after the first is full. Parallel being the electricity goes simultaneously to both LED at the same time. Is parallel bad? I have my two B&M LED lights in parallel from the Shimano dynohub. Seems to work just fine. I'm surprised that seems to work fine. Series is normally considered correct. It seems two identical lamps in parallel would each get 1/4 amp. LED headlights do better than halogen, etc. at low current levels, but I'd have thought those would still be dim. If they're not, that's interesting. If I were you, I'd wire it with switches so I could change between the two systems (series vs. parallel) while riding. Compare and report back! -- - Frank Krygowski I am not an electrician. Never claimed to be. Except with house wiring. 110/220 switches, plugs, lights, outlets. On that I consider myself very competent in the practical work. Maybe not on the theory part. Never had any need to learn about 3 phase inverters since all my tools are single phase getting supply from single phase breakers. My bike had old halogen bulbs on PBP 2007. I believe one of those two lights was a special series light so the dyno would send power to one of the lights first and then only send power to the second after getting up to speed.. I think B&M or whoever made the lights specifically made those second lights to use in that way. But with my newer B&M LED lights I just wired them parallel. No one bothered to make that special second light for LED because everyone thought LED was good enough with just one bulb. No need for two lights with LED unlike with halogen where the second bulb in series was kind of necessary. Equal full power to both lights simultaneously. Now at lower speed both lights are weak. But since LED lights up at fairly low speeds, it only takes about 7-8 mph to get both LED lit up to full brightness. So no real downside because I never ride slow enough to not get both lights going full brightness. |

I think "safety inflation" is real. It applies not only to bicycles, it's pervasive in modern American society; I can probably give dozens of examples. I own books on related topics. But it certainly does apply to bicycles and bicycling, in many ways that have nothing to do with making it easier to ride. Again, I can give examples, although you can certainly think of them yourself. I don't know why this observation is so distasteful to you. In spite of the safety inflation of chilumen bike lights, the rampant policing of bicycle helmet wearing (in Melbourne/Australia) and shaming of people for not wearing hi vis clothing, wearing earbuds, or riding a little too fast in a shared pedestrian/cycling zone; Fatalities in the state of Victoria/Australia show an increasing trend (which is difficult to see where the annual fatality rate was approximately 8 a decade ago, but is now closer to 10), and the reported injury count has changed from about 300 annually to 500 over the same period, _and_ according to the National Cycling Participation Survey, regular cycling has lost about 200,000 people over a similar period.. So safety inflation, targeted policing and fewer people cycling regularly has resulted in more deaths and injuries. Yay! You need to take the long view. The trend is good, in that when bicycling drops to ever lower numbers and bike injuries climb ever higher, people will finally accept that riding is incurably dangerous. It will become much easier to outlaw it entirely, thereby preventing those ten deaths per year. (And people must not be allowed to bring up comparative numbers of deaths or injuries due to motoring, pedestrian travel, cardio-vascular problems, etc. Those are off-topic!) Yes, soon you'll be driven underground and will have to ride a Peloton bike! Did you ever wonder why indoor bicycling is as popular as it is? No -- but if you're saying its because people are cowering in fear because of safety inflation, then you're out of touch with the gym scene. Let me interject that you seem a bit confused about what "safety inflation" is intended to mean. It's more complicated than simply labeling something as dangerous. It's a demand for ever more safety precautions, with the implication that what was recently considered adequately safe is now considered dangerous. If you want to discuss this, you might keep that in mind. There have always been people who feel riding a bike on a road is dangerous. Most of them are demonstrably wrong (although most probably wouldn't understand the demonstration). I'm sure that a large number of indoor cyclists (a group comprising much more than the "gym scene") are part of that fearful group. But that in itself is not necessarily evidence of safety _inflation_. Perhaps the charitable way to describe it is timidity caused by lack of knowledge. And a lot of what you call safety inflation is people just not wanting to deal with traffic. You're definitely missing the concept. Let's try a non-cycling example. I just borrowed a friend's new car to get takeout food for a shared dinner. Some of its features, compared to cars deemed safe enough 15 years ago: Instead of two airbags (once considered plenty) it has a constellation of airbags. Pretty much the entire interior inflates in case of a crash. It's safer than before. Instead of simple side view mirrors (once considered sufficient) it has mirrors with internal turn signal lights and a sensor system to tell if there's a car in a blind spot. It also has lights in the mirrors that come on any time a door is cracked. They're safer than before. Of course it has anti-lock brakes. Those were on some cars 15 years ago, but now they're on all cars. Because it's safer. It has "lane departure assist" or something like that. It nudges the car back in the lane if it "sees" you getting too close to a lane line. Somehow, we used to be safe enough without that. It has all wheel drive, even though it's not an off-road vehicle and never will be. I've always felt safe enough being driven by just two of the four wheels. But all wheel is now promoted, for "safety" reasons, on regular roads. It has a backup camera. Once upon a time, we used mirrors to back up. The camera is easier, of course - but it's also safer. I could probably go on, but here's my major point: There was a time when nobody thought a car was dangerous because it had only belts instead of air bags, simple mirrors without cameras, ordinary brakes, two wheel drive and steering that you had to operate yourself to stay in a highway lane. But now, at least for many people, that's just not safe enough. It's possible to give a myriad of other examples, not just cars or bicycles. Safety inflation is a fact. Again, I don't know why pointing this out offends you. -- - Frank Krygowski I'm going to argue with you Frank. About your car safety, convenience, improvement features you mention. Money. Most folks would say more is better when it comes to money. More money better. Safer cars better. Safer bicycle rides better. More lighting better. Is it inflation or better? Isn't making bicycling safer better? Kind of like more money is always better than less money? I know some folks say they have enough money. But if they could have more money wouldn't that be more enough? And better? |

Riding with a cycling cap or no cap at all was once plenty safe, but now draws finger wagging, taunts and lectures from intolerant people, even ones who should be allies. It's an example of "safety inflation." In fact, there are many who think it's better to never ride a bike, than to ride one without a helmet. That's flagrantly stupid and contrary to all research I've been able to find. We don't need to duplicate that stupidity with DRLs, no matter how much some may love the gimmickry. -- - Frank Krygowski Funny, in all my years of riding without a helmet, I've never been told that I should be wearing one. That amazes me. IIRC, you live in Ontario, where a mandatory helmet law for adult cyclists was barely avoided. (One of the leaders of the successful opposition was a man who used to post here frequently.) There is no statewide MHL here in Ohio for kids or adults. But I've been yelled at by passing motorists, including one who was blaring her horn and yelling at me to ride on a sidewalk. I had a car of young girls deliberately brush-pass me then slow way down as one yelled "Wear your F*** helmet!" I had a bicyclist cuss me out long and loud for not wearing one. And I've had many milder "Where's your helmet?" remarks delivered in scolding tones, from everyone from fellow club members to pedestrians on the sidewalk. Move! Get out of that 'hell hole'. Rode alone today and according to my 'helmet wear algorithm' I didn't wear a helmet. No one yelled or honked at me. It was cold for the time of the year (5C) but it was a pleasant ride after a rainy day yesterday. We just now got back from a ride for groceries. Nobody yelled, which is normal. But as I've said, unlike Sir, it has happened to me many times over the years, and not just here. I was yelled at in a Portland suburb. (I was also yelled at to "get in a bike lane" there, on a street that had none.) Idiots abound. We don't need to give them more ammunition. Regarding bicycling, this is the opposite of a hell hole. As I've said, we have hundreds of pleasant, small country roads to explore. On Friday's ride with a friend from the other side of town, I chose the route; but about halfway through the ride I said "I forget where that little road goes. Do you mind if we explore?" Nobody did, so we poked around for an extra 5 or 10 miles on roads with almost zero traffic. I did eventually have to check the GPS to refresh my memory; but it was a perfect cycling day, with beautiful skies and trilling toads serenading us the whole way. People yell at you in Portland because you just don't fit in. Next time try a little arson of Federal property, they'll take you for a local: https://nypost.com/2021/04/11/portla...lent-protests/ (Safety note: Wear a Che Guevara or Biden or BLM (CCP) tee shirt as protection from indictment) These dopes are being rounded up slowly -- often out of state. We have protest tourists. https://www.wfyi.org/news/articles/i...tland-protests "tourists" Is that what they are called. Wisconsin, Andy's state, had Kyle Rittenhouse from Illinois kill two people and shoot a third person while he was a "tourist" in Wisconsin. https://www.usnews.com/news/us/artic...onsin-protests Of course those being murdered were "protesters" at a Black Lives Matter rally, or some protest about a black man being gunned down by police. So obviously the protesters needed to be shot down dead by a 17 year old white boy visiting from across state lines. And the protesters are not even on the radar from a cycling standpoint. IMO, the right-thinking conservative PU drivers are worse than all of the Antifa hooligans put together. Poor Frank got yelled at and told to get in a bike lane. Riding way out in Clackamas, Yamhill and Washington counties, I've had much more dire encounters with MAGA idiots with Trump flags and bumper stickers -- for just riding on a f****** road. -- Jay Beattie. |
