"she switched to the local park, Flatwoods, near her home in Tampa, Florida, to complete a 7-mile loop over and over again" "as Amanda had suffered a serious brain injury whilst cycling in 2011 when a car hit her at 50mph. Flatwoods wasn’t the only place she cycled, but it helped the family keep an eye on her, as even in Flatwoods she was being pestered by men while on her bike." "After my crash, I wasn’t sure that I would ever cycle again (Amanda was left with a broken leg, a back injury that eventually led to surgery, cartilage and tissue damage, deep bone bruising, hip, knee, ankle and foot injuries and a Traumatic Brain Injury)." Her riding was done between May 2016 and mid 2017. "pestered by men while on her bike". I am sure glad Trump was in charge during part of her ride to Make America Great Again. We need American men to harass, molest, assault, twenty something age girls on bikes. Trump won Florida electoral votes in 2016 and 2020. |

It's fine for her occasional use. Correct, a Sanyo Dynapower. I bought it for the Peugeot PR 60/L shown in the link above with an Union bottle generator. At that time I used the Peugeot for commuting during sommer and winter, with various lights. I tried almost everything, and broke almost everything available at that time. I'm retired for more than three years now and mostly don't ride in the dark anymore. But as a backup and because it's the law, I carry an b&m Ixon Core in my bag and an Sigma Blaze mounted at the seat post. https://www.bumm.de/en/products/akku-scheinwerfer/produkt/180l%20.html https://www.sigmasport.com/en/images/sigma_website/produkte/slider/slider_blaze/slider/01_slider_blaze_black.jpg I tried one of those Sanyo Dynahub roller generators and did NOT like the beam pattern with the included light/ That beam pattern was a long T with both portions of the T being very narrow. Maybe with a different light it would have been better. It was. German law (StVO) made a lot of detailed and very specific technical requirements for biycle lights mandatory, including a mandatory generator to provide exactly 3 W at 6 V to the light in front and the taillight. Even the light bulbs needed a specific registration. For example, this bulb https://www.mystrobl.de/Plone/radfahren/technik/komponenten/licht/P1050738a.jpg has the registration number K16429. First hit with DuckDuckGo: https://www.amazon.de/K16429/s?k=K16429 These still are in use around here, on very old bikes having had no maintenance since thirty years or so. But most new utility cycles are sold with hub dynamos and led lights, for many years now. I initially used a Busch & Müller Lumotec lampe like this one: https://images.internetstores.de/products/364367[1920x1920].jpg Requiring registered bulbs in those lamps wasn't entierely moot, because it guaranteed the neccessary position and size and position of the the filament and so sensible beam pattern. Unfortunately, the very same law didn't allow anything else, neither 12 V, nor more than 2.4 W for the front bulb and 0.6 W taillight. That's not much with a non-halogen light, even with a good parabolic reflector. I also thought about cutting out a section of rear fender on my cantilever brakes touring bike and then mounting the dynamo to the brake bridge. However the lousy beam pattern meant I had no interest in doing that. I switched to an lead acid battery, already mentioned, plus a second lamp (Lumotec, too) using a different bulb as a full beam - essentially overvolting by using a compatible bulb having a lower nominal voltage. Illegal of course, but necessary for my commute. -- Wir danken für die Beachtung aller Sicherheitsbestimmungen |

I'm sure recent improvements are better. But not much better since there wasn't much to improve. Well, this is why I don't really like these ****ing contests wrt. innovations. Sometimes, progress comes in tiny steps, almost invisible. Anyway, there was a lot to improve. Modern brakes work better when the rim is wet and have a lot less hysteresis. I guess some of the disc brake hype comes from people switching from old rim brakes to new disc brakes. Awhile ago cars had drum brakes. Did cars ever have rim brakes? All cars have disc brakes now. Not yet. Our family car still has drum brakes on the rear wheels. It doesn't matter, cars aren't bicycles. The old drum brakes worked. Still do. I am sure disc brakes are better. An improvement. A necessary improvement. Yes. But I don't think it was like we went from rear end crashes on every single drive to rear end crashes once a decade when brakes changed from drum to disc. Disc brakes work better than drum brakes in cars. Perhaps. I believe that having drum brakes in the rear may have a slight advantage, in a car. But using a single technology has advantages to, so switching to disc brakes does make sense. New bicycle disc and sidepull and cantilever brakes work better than the much, much older centerpull and sidepull brakes on bicycles from long, long ago. But it ain't night and day, life or death different. Indeed. There is far too much fear mongering around bicycles, much of it driven by ignorance and hype. -- Wir danken für die Beachtung aller Sicherheitsbestimmungen |

I changed the brake calipers on my winter bike from cantilever to V-brakes (also changed the brake levers) because I found a HUGE difference when trying to stop in wet snow and/or slush. The V-brakes would stop almost instantly where the cantilever brakes would maybe slow the bike down a bit at first. Those cantilever brakes were properly set up too. I switched from hydraulic cantilever brakes (Magura) to a cheap V-brake on the bicycle used during winter for my commute, starting in '96, after the Magura got stuck now and then on one side. Didn't have any problems afterwards. Disc brakes may that good now, but they certainly weren't then, so this wasn't an option. I think another big advantage with disc brakes besides their stopping power when wet or snow, is that the wheel does not have to be perfectly true in order to prevent brake rub. I think that's a big part of why they're so popular on MTBs. Perhaps. But I don't own or ride a MTB, I don't even ride on anything that isn't paved with asphalt. On the other hand, I heared people taling about having damaged their disks on long descents. A disk has less heat capacity compared to a rim. Actually, disc brakes allow much less clearance between disc and pads than rim brake - that's the very reason for those differences, a larger ratio. So a slightly deformed disc is already unuseable, because it gets stuck, where a rim is not. I certainly watch the disc brake space, but IMHO there is much hype, partially from users and about use cases different from mine. So I remain slightly sceptical. -- Wir danken für die Beachtung aller Sicherheitsbestimmungen |

Instead of someone having to manually move the sewing head(actually the spread fabric), they can just feed commands into the X & Y motors and the thread quilting pattern can be made very decorative. In the 1960's and 70's, my fathers lingerie factory in Smog Angeles was near a factory that did "computerized" embroidery. The Swiss computer was in 7ft tall, 19" relay rack. Programming and storage was on rather large punched cards, very similar to the original 1800's Jacquard loom except that it used needles: https://www.google.com/search?tbm=isch&q=jacquard+punched+cards https://en.wikipedia.org/wiki/Jacquard_machine Basically, it was an automated version of the needle embroidery paper template. "Punching a 12 stitch repeat card on a 24 stitch repeat punch card" https://www.youtube.com/watch?v=JnwaKaMXSJA In other words, for 200 years, the improvements in mechanized embroidery were small evolutionary improvements and refinements of existing technology. During the 1980's, computers arrived and changed everything. While the older mechanical computerized machines operated at the speed of a mechanical ratchet, the computerized servo and stepper motor driven machine could go much faster. Suddenly, there was a reason to improve the underlying mechanical technology. For example, the switch from one needle, to over a hundred needles. (The most I've seen were was about 100 at a trade show about 20 years ago). For example, 15 needles and 2 heads: https://www.toolots.com/double-head-15-needles-embroidery-machine-with-pattern-design-system.html Notice that the above machine is controlled by a small tablet computah. Controlling such a machine with punched cards would have been impossible. It's much like the transition from steel frames, to aluminum frames, and now to carbon fiber. The requirements of each material established the limits of what could be done. For example, when aluminum tubing arrived, frame makers were building frames almost exactly the way steel frames had been previously built. With water, sand, or hydraulic fluid filled tubing benders, they could produce weird looking frames that resembled a pretzel. Add some shocks and these became the current standard for mountain bicycles. The odd geometry is not particularly revolutionary. The method of efficiently bending tubing is. -- Jeff Liebermann PO Box 272 http://www.LearnByDestroying.com Ben Lomond CA 95005-0272 Skype: JeffLiebermann AE6KS 831-336-2558 |
