On the other hand, when during an experiment to see how low I could pressurize balloons I had an instantaneous blowout at just under 50kph on a bump or a pothole at the bottom of a hill, I was at the top of the next hill from pure momentum before I thought it wise to apply brakes. Wrecked the tube and tyre, of course, but the rim was good as new after a fairy pass with a piece of sandpaper. Andre Jute Not that I actually know what a short ton is, but it has to be less than a long ton, which leads to an inconvenient fraction |

A short ton is 2,000 pounds and the standard in the U.S. The long ton is 20 hundredweight (2240 pounds). Just to confuse us, the metric tonne is 2204 pounds.

He wasn't too happy, so I had to point out that he can't just pick and choose which laws he could be bothered enforcing - If he CBA enforcing the laws that keep the roads safe; he'll have to put up with cyclists on the footpath. |

I like my bicycles and I enjoy riding them, bereft of modern 'features' though they remain. A lily gilded is no longer a lily at all IMHO. I believe we've had this discussion once before. I don't think there are any readers of rec.bicycles.tech that would be considered customers for the strange concept bicycles, weird accessories, and odd ideas which I have been excavating from obscurity or contriving for the occasion. The most likely audience are those that want something different, unique, weird, ostentatious, or which solves a specific problem. While bolt on accessories might be considered gilding, they do constitute a substantial part of the bicycle business and are unlikely to disappear at the mere mention of minimalist cycling. Besides, we've already experienced a minimalist reaction to excessive bicycle features in the form of the fixie. Like all such pendulum swings towards any extreme, they tend to overshoot, such as bicycles without brakes: https://www.theguardian.com/travel/2008/mar/09/green Gyro stabilized bicycles are certainly not going to take over the cycling market. I had hoped they would become an expansion of the Segway "personal transporter", where a gyro and reversible electric power might make a bicycle do some rather useful tricks. For example, following the walking owner while standing on its rear wheel, or operating safely in reverse. I'm also watching a slow creep of motorcycle technology find its way into bicycles, mostly via eBikes. For example: https://techcrunch.com/2011/02/11/segway-2-0-german-bicycle-on-steriods-comes-to-the-us/ http://www.maketechx.com/erockit-green-bike-project/ I've suggested this before, but might as well try again. Put a modern concept bicycle or the most atrocious example of a stylistic bicycle-like machine in your showroom. https://www.google.com/search?tbm=isch&q=concept+bicycles https://www.google.com/search?tbm=isch&q=molded+plastic+bicycle If that's too much, maybe a life size poster hanging from the wall. You might sell one to someone with more money than common sense, but you will get into many conversations with gawkers and loafers, whom you can then steer in the direction of a more conventional bicycle. That's why auto dealers have red convertibles in their show rooms. Nobody buys them, but they attract quite a bit of attention from middle aged drivers wanting to relive their youth. Gadgetry is a customer magnet. -- 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 may have known once, but I'm very efficient about uncluttering my mind, not letting irrelevant facts interfere with essentials; I have no problem admitting to not knowing something, including something I may have known last week or last decade. There's always someone who has reason to know and is happy to share. but I'll spell it out for the audience at home. I admire that. My mother was a teacher, from a family of teachers and preachers. A short ton is 2,000 pounds and the standard in the U.S. The long ton is 20 hundredweight (2240 pounds). Just to confuse us, the metric tonne is 2204 pounds. Aha! it must have been the metric tonne I was thinking of which leaves an inconvenient fraction. Thanks for taking the time to straighten me out. Andre Jute Profundity enabled by the net |

THE CONCEPT advanced to fruition is a for sale transportation system covering a small city area.
The Company selling electric vehicles (Topo, linked Topo ), road equipment and computers/software to the small city. So, you would have a commuter plan in the system, get in Topo, press a button n wait for a spot then zooom zooom zooom off to the place of work. |
