Proabably YouTube: https://www.google.com/search?q=bad+cycling+video&oq=bad+cycling+video https://www.youtube.com/results?search_query=bad+cycling Hopefully, his cameras have image stabilization. I suspect that you have the wrong idea about the real purpose of wearable bicycle cameras. They are not there to produce yet another spectacular cycling sports video as the folks at GoPro might suggest. They are also not suitable for post mortem cycling evidence suitable for playing at the funeral or in the courtroom. They are actually a talisman to ward away evil spirits and prevent cycling accidents. https://en.wikipedia.org/wiki/Talisman I can offer anecdotal tesimony as to the effectiveness of such cameras. Ever since I installed a front/rear dashboard camera in my Subaru, I have not experienced a single accident or near miss while driving either forward or backward. Obviously, the presence of a camera is all that is required to produce this highly desireable effect. Granted, this is with an automobile, but I presume that it's much the same with a bicycle. I have disposed of my former good luck charms (rabbits foot, railroad spike, four leaf clover, mojo bag, shark tooth, etc) http://www.thisisinsider.com/good-luck-charms-different-countries-2017-3 and currently rely solely on my dashboard camera talisman for my personal safety. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

Races have been won with less than 1% mechanical advantage. The amazing part to me is that the rear drive shaft pinion gear doesn't bend the rear sprocket inward. At the angle shown in the photos, the drive shaft bearings look like they can produce almost as much inward lateral force on the rear sprocket as they do making the wheel go round. The rear sprocket is supported by 12 thin radial spokes, that don't look strong enough to handle much lateral force. As long as the drive shaft bearings are sitting at the bottom of the rear sprocket teeth, there won't be much lateral force. However, when these bearings slide up the sides of the rear sprocket teeth, the lateral force will increase drastically and might either bend the rear sprocket, or shred the leading edge of the sprocket teeth. Using bearings instead of ordinary gear teeth will certainly help, but I don't know how much it will help. There's probably a similar problem with the front sprocket where the front drive shaft bearing is trying to bend the front chainring outward. Also, I wonder if the drive shaft uses a thrust bearing for shifting, and how much pressure is on this bearing. The market is starting to look like the late 1800s with steam powered nose-hair trimmers and other exotic Rube Goldberg contraptions. And then all the safety devices. What does it mean? -- Jay Beattie Where have you been the last few years? Kickstarter and other crowd funding sites are full of badly conceived great ideas that will never sell or work. It's been like that since the beginning of history, where someone designs a better product to save humanity from itself, or just to separate the customer from his money. The only difference is that todays great ideas can sometimes get funding for something that is clearly impossible, and no matter how original an idea, the patent sharks are lurking and ready to sue. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

If I decide to weaponize one of my bicycles, it might give me some ideas on what can be done. If my bookshelf collapses from being overloaded, it's your fault. Incidentally, one of my friends has recently morphed into a "prepper" and "zombie apocalypse" enthusiast. He's outfitting his ancient Stumpjumper with survival supplies in case the SHTF (s**t hits the fan) in case he needs to "bug out" quickly. (Sorry, but I'm just learning the lingo). https://www.google.com/search?q=prepper+bicycle&tbm=isch So far, I'm impressed with his thinking and suspect that my efforts to weaponize one of my bicycles will follow his example. Eventually, the bicycle manufacturers and custom builders will discover the prepper bicycle market, release similar products, and pollute the market with innovative but impractical designs. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

Oh, there's been a big uptick in the populist "bikes don't belong" brigade in the past couple of years hereabouts. Some of that is due to some high profile fatal bike-car collisions (three that I can think of offhand, two of which apparently involved the cyclist running a red light or stop sign and the other a hit-and-run drunk driver). Some of it is due to several thoroughfares getting badly designed bike lanes that also resulted in homeowners and businesses losing onstreet parking and/or the loss of a lane of traffic, resulting in backups many blocks long while drivers have plenty of time to contemplate the empty bike lanes (we have a Minneapolis Bike Coalition and a St. Paul Bike Coalition that have sprung into existence to push for these in the past few years, neither of which seem to have the foggiest notion of competent bike lane design). My favorite compliaints are the grousing based on the canard of "bikes don't pay taxes" and that we are therefore getting to use the roads for free. I wonder where all that money I send to the government goes, if I'm not paying my fair share of taxes. |
