I propose that the problem that all these solve is a better fit, not just for the rider, but for the road conditions, situation, and style of riding. Instead of owning individual bicycles for road, track, dirt, gravel, acrobatics, electric assist, comfort, and show, a fully adjustable geometry bicycle could rapidly be switched from one mode of travel to another. For example, you're plodding along on your daily commute in a rather conservative commuter configuration, when you are challenged to a race. Rather than ride home and return with your road bicycle, you punch a few commands on your BT connected smartphone, and instantly your frame geometery changes into something like a road racer. You win the race, punch a few buttons, and arrive back in the conservative commuter configuration. Such adjustable geometry can also be used to compensate for small limb length discrepancies. With a little imagination, making all the components adjustable will be revolutionary (or revolting). Anyone using a non-dropper seatpost is standing in the way of human progress. Ummm... it's bicycle progress, not human progress. It's the bicycle that is changing, not the rider. You left out electric charge reactive finish color control (like window tints).

It can be done with a camera, computah, and electrochromic or paramagnetic paint as active camouflage: https://www.google.com/search?tbm=isch&q=active+camouflage https://www.google.com/search?tbm=isch&q=electrochromic+paramagnetic+pain t https://www.google.com/search?tbm=isch&q=color+changing+car+paint It would be easier if the bike frame and components were made from glass or transparent plastic. However, that begs the question why would you want an invisible bicycle? Invisibility would make you an instant statistic and accident victim. A much better use for a computerized bicycle would be to improve the visibility of the bicycle and its rider using contrasting color changes and illumination: https://www.ebay.com/itm/Bike-Wheel-Lights-20-Bright-LED-String-for-Safe-Night-Rain-Cycling-Spoke-Attach-/162432780393 Ideally, it should also be possible for the rider to wear a color changing vest. If riding next to a dark black car, the camera would recognize that white would be a good contrasting color and light the vest with white LED's. If riding next to a white colored car, black might be useful, but I think a checkerboard pattern might be more visible. Note that the vest need not contain its own power source or computah. The camera, computah, and power system can all be part of the bicycle of the future. We return you now to the present reality, where the possibilities of a bright, safe, and entertaining future are limited only by the reactionary attitudes of those who perpetuate mediocrity through simplicity, conservative design, rules, tradition, and standardization. Were it not for these obstacles, bicycles would have long ago been upgraded to rocket powered jet backpacks and other futuristic transportation devices: https://www.google.com/search?q=rocketeer&tbm=isch -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

I recently read a news item that said young people were queried about how much they played computer games and it turned out that they were playing computer games 4 - 5 hours a day. Exercise is obviously a thing of the past for the younger generation :-( -- cheers, John B. |

Should pro road racers use dropper posts? https://www.yahoo.com/sports/worldto...11819293..html If they do, it won't be long before anyone who uses an ordinary seatpost will be scorned as a luddite. -- - Frank Krygowski I believe a dropper seatpost in professional road bicycle racing might be a safety benefit. Currently, racers descending a mountain will frequently put their groin and belly and chest onto the top of the toptube to become as aerodynamic as possible. This is a somewhat/definitely unsafe position to control a bicycle when descending. But with a dropper seatpost, the racer could get himself into the low aerodynamic position, AND remain seated on the saddle. Overall a much safer position to descend a mountain. So a dropper seatpost would be an easy safety enhancement for professional bicyclists. Who would be against increasing the safety aspect of professional bicycle racing? |
