At that time, 800 lumens will be reserved for purists and regulatory agencies.

Mortally afraid is more like "it would be stupid." I have enough lights. Yep, safety inflation is real. Since when is being able to see "safety inflation"? Let's go for a night ride sometime, you and your bottle dyno and light, and me and my whatever light I chose. I'll wait for you at the bottom. On flat roads and the bike path through South Waterfront I can get by with a little flea-watt flasher or a clip on flashlight from 1968 -- or my old Wonder Light. But that is not where I do (or did pre DST) most of my riding. Frank is not acquainted with Portland's exotic rain-forest, mountain-bunny routes. If you are interested in a regular contest, ask a local, like your son, to take the dyno lamp. Make sure you use Specialized's prototype Zn-C matrix battery fork for extra power! Everything involves a descent, often on old broken concrete roads. I've done those on dyno only, and its inadequate except at a creeping pace. When will you finally invite a few fixie-riding antifa for a blissful summer of subbotnik road repairs?! Oh, wait, repairing and recreating historic concrete plates is horrendously "CO2 emissions intensive." If you aren't Al Gore, you simply won't get a permit. They don't re-do concrete, at least not often in town -- it gets asphalt. One of my routes was repaved in the last year or so, but I think some of neighborhoods don't want repaving because the broken concrete roads act as natural speed bumps. Two, essentially parallel streets: https://tinyurl.com/4n2dfzp8 and next door: https://tinyurl.com/kdrfm2t8 Look out for the manhole down the street: https://tinyurl.com/8a8w383f I have no idea why they paved one and not the other. I rarely go down those roads -- they're part of the return route from anywhere east, and my pre-plague commute home. I creep up them, LUXOS B blazing the way. This is where I see people's feet before the people -- or their dogs with lighted dog vests. -- Jay Beattie. I would comment that those are appallingly poorly built roads. It appears that they simply laid concrete over an existing, probably, dirt road. I would guess that the residents bitched about a dirt road and so the highway department slapped some concrete down and said "There! A paved road". Apparently that happened here. Our County Engineering office always has a booth at the annual county fair. One year I asked about that - about the process by which farm roads that were once gravel on dirt got paved. The young engineers staffing the booth looked at each other, then explained that long ago (maybe the 1950s or 1960s?) the guy who was county engineer got re-elected by suddenly paving a huge number of roads. But the "paving" was just dropping asphalt on top of existing gravel, with no preparation at all. I know our county is notorious for potholes. It's not unusual to follow an ex farm road across our county line and see a huge difference in pavement smoothness and quality. -- - Frank Krygowski |

Where is the link to the forum post that has this image? It's in the "Welcher Dynamo Scheinwerfer?" thread inside the forum's Elektrik/Elektronik section, but there are no blueprints or schematics to look at -- or to send to CCP 1/10 Cost Corp. If you weren't too autistic to look a bit closer at the pcb, you would have found the search term for YT, and hence, Mr. Schadt's homepage. No offense, but I don't think his weekend microbusiness is set up to handle culturally incompatible inquiries or nerve-wrecking suggestions from India or Scharfie County. Hopefully they included thermal sensors to automatically reduce power to prevent overheating. Probably, but if you are prone to overheating it, you are not in the intended target group. It's an assembled conversion kit, the buyer won't even receive a real manual, not French, not German, not even Mandarin. It's an interesting concept but IMVAIO it's backward. Instead of adding an optional battery to a dynamo light, it would be more logical (and much less expensive) to add optional dynamo operating and charging to a battery powered light. You can get a much more capable fully-featured headlight, with internal Li-Ion batteries, for 1/3 to 1/4 the cost, and a circuit to charge the batteries from the dynamo is trivial (snip) You are entitled to your opinion. Why don't you ask PJW about a rough estimate on the total number of dynamo input adapter sets he has ever sold to fit an early Hella battery LED lamp he offered? A dozen or two? I might have seen one such adapter in the wild, in Europe, more than a decade ago. I also do not believe in significant demand for high-wattage dynamos, not even for ebikes: The moment a jurisdiction stops requiring a dynamo for pedelecs, hardly anyone bothers to fit one (or more). |

snip So safety inflation, targeted policing and fewer people cycling regularly has resulted in more deaths and injuries. You're using "F-Logic" of correlation not causation. Do you claim that the reason that cycling rates are down (assuming the survey is accurate) is because of helmet requirements and the availability of high-lumen lights? Are there Australians that say, "screw the helmet requirement, we'll own the libs by giving up cycling and eating junk food and drinking Fosters?" In terms of children cycling, Section 3.2 of the study states "A great deal of cycling participation occurs among children, for whom much of this riding occurs off public roads in parks and backyards. Such trips are unlikely to be measured by any automatic or manual counting program. A change in childhood cycling participation will have significant effects on overall cycling participation but may not be detected as part of counting programs." You also can't really conclude that increases in injuries and fatalities are due to changes in cycling rates. In the U.S. cycling participation increased from 39.69 million in 2006 to 48.88 million in 2019 (2020 will show an enormous increase but it's an outlier and it remains to be seen if the increases will hold). Death rates for each year vary but don't correlate with the increase in cycling rates. Some age groups had increases while some age groups had decreases. The statistics don't specify the number of cyclists in each age group. The fatality rates for younger riders fell while the rates for older riders went up. Speculation is that more helmet laws for those under 18 helped reduce fatality rates in those groups, but this study doesn't prove that one way or another. Transportational cycling rates vary greatly based on factors unrelated to safety equipment. I first visited China in 1987 and cycling rates were extremely high. But that was because the only affordable alternative to cycling was generally a public bus. Cycling rates are way down now because all the large cities have extensive subway systems and because the increase in wealth means more people have cars (generally not used for commuting, but used for things like trips to Costco). Climate change has also affected cycling rates in some locations. In urban areas of the U.S. where cycling rates have increased by substantial amounts it's because of the large increase in cycling infrastructure. A big push in my area is "Safe Routes to School." We have terrible traffic jams around schools and a Catch-22 of parents driving crazily, which makes parents reluctant to allow their children to walk or bike to school. When one 8th grader e-mailed me about a problem near his middle school (cars driving on the shoulder where cyclists want to ride) I called the sheriff and asked for some enforcement in that area and they came out and wrote a slew of tickets but we can't hire enough deputies to patrol all the schools at peak times you need to put in traffic calming that physically prevents the bad behavior. |

But you can be certain that there will be individuals that cherry-pick statistics and look at a decrease from 2020 to 2022 and proclaim that it's "Safety Inflation" that has caused the drop. I still recall one anti-helmet website that first claimed that cycling rates fell after a helmet law somewhere was adopted. When it was pointed out that cycling rates actually increased they changed their narrative to "well cycling rates increased slower than population increased so the rate as a percentage of the population decreased even though the absolute number increased." It's like dealing with Trump supporters, facts and logic are of no use. |

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. My brother went to spin classes with his wife, and he was a fearless three state old-guy DH champion and went to worlds. I've ridden many miles with him on the road. In fact, I rode with their spin instructor who placed in LoToJa. Strong guy -- one of the hardest centuries I've done in recent history. People have lots of social reasons for living the gym life . . . although some may be afraid of riding on the road. That has to be true statistically because some people were afraid of riding on the road even before flashers and helmets were even a thing. And a lot of what you call safety inflation is people just not wanting to deal with traffic. It sucks dealing with traffic, dangerous or not. When it comes to picking routes, I take the one with the least traffic. Who wants to breathe exhaust and deal with the homicidal PU maniacs in the 'burbs. No amount of lane-taking makes that pleasant. "Position one!" [cough, cough, gag . . . as diesel PU number four passes within an inch, leaving a cloud of smoke]. People may prefer Plan B, i.e., not riding on the road. https://cloudfront.traillink.com/pho..._148788_sc.jpg Or Plan C. https://i1.wp.com/buckyrides.com/wp-...00%2C900&ssl=1 That also includes Plan D, which is usually low traffic. https://farm1.staticflickr.com/280/2...85fc52d273.jpg That's a great ride. Which reminds me, I was riding on that road in the last picture (Marmot Rd.) with a friend of mine with whom I've been riding for 30 years. He now refuses to ride on Skyline because it is dangerous and refuses to ride the foot of SW Terwilliger -- preferring the adjacent path through the woods. https://tinyurl.com/85c27nx6 Totally reasonable fear. I now take the side path because climbing in the middle of a road with a blind turn and posted 45mph limit (actually 50) and twice the traffic of 20 years ago is objectively scary. Why bother. And to be honest, I usually skip the side path and go up a whole different road -- past the trestle house. https://tinyurl.com/vt3z3x3w Anyway, its not just a bunch of scared Nancies who want a facility or some option other than riding in traffic. -- Jay Beattie. |

True. The fastest routes for cycling around here are the expressways. Few lights, wide shoulder, safe, and very direct. But it's very unpleasant. In any case, cycling numbers continue to rise in the U.S. (even before the pre-Covid surge), helmets continue to improve with MIPS becoming standard even on lower-cost models https://www.costco.com/freetown-gear-%2526-gravel-lumiere-mips-helmet.product.100587455.html, lights continue to improve and get cheaper, bicycles continue to improve (at least in some ways that improve safety), new cycling infrastructure continues to be built. All much to the chagrin of those that would prefer fewer cyclists be out there and make up fantastic fictional stories to promote their personal agenda. How much of the 2020 surge in cycling can be maintained? Some of the surge was because of gyms being closed, some was because of a desire to avoid public transit.
