    Fun with AI

    Absolutely! Learned to deal with space-time rifts and subspace tachyon field vortices from Star Trek, but they had nothing on this stuff.

    Fun with AI

    Lots of sound advice there. Hate it when I trigger causality spasms — especially before I've had my morning coffee. And unleashing the wrong kind of unstable divine energy can ruin your whole day — or maybe even the whole planet's day!

    You've really outdone yourself on this one! I can imagine your mind constantly fighting back a flood of possible puns — even when you're trying to be serious. ;^}

    Probably shouldn't pick his nose, either.

    Hi Everyone

    Welcome aboard! We'd love to see your bike and the places you ride. My 3 favorite forum threads are the ones for sharing ride photos. https://forums.electricbikereview.com/threads/2025-our-rides-in-words-photos-maps-and-videos.57230/...

    Playing what-ifs with an interactive power vs. speed model

    If your rider power changes a lot over the course of a typical ride, or you're doing a lot of accelerations — say, due to traffic — normalized average power's a better metric than simple average power. Guessing that riding your regular bike is significantly easier than riding your ebike in OFF...

    Playing what-ifs with an interactive power vs. speed model

    If both data sets were from the same route ridden the same way, comparing the 2 bike's kcal per mile figures would be a good start. But one route is 8.6 mi, and the other is 8.15 mi. And I don't see any climbing info on the 2nd route. So I don't see a basis for a valid comparison based on the...

    Another new TQ motor: hpr40

    Setting segment assist levels like you did — higher than you'll likely use — is a good way to pad the range estimate in favor of getting home under power. We expect a full report with photos. ;^}

    Playing what-ifs with an interactive power vs. speed model

    I don't see it making the doing of cycling any harder. But it can make thinking about certain aspects of cycling easier. And that's the whole point. Guess it's a matter of personal taste. As with all my other hobbies, I enjoy thinking about my riding as a process sometimes. Only makes riding...

    That's a beauty! Corvids are sooooo cool. Deserving art subjects. Please show us all you find.

    Playing what-ifs with an interactive power vs. speed model

    Resistance to forward motion is an ever-present foe in cycling. In the spirit of know thine enemy, here's an interactive visualization of the 3 main power losses due to air, gravitational, and rolling resistance. It's made in the Desmos online graphing calculator...

    Fun with AI

    After successfully repainting my bike with AI, seemed time to work on the crusty old rider. Tried several prompts along the lines of "make the bike rider look like a pro racer in a yellow jersey". Even asked for Pogi specifically. Apparently, there are things too far-fetched even for AI.

    SoCal's totally out of the path of visibility this time around, but we had a 60% solar eclipse on April 8, 2024. The only (phone camera) photo I got that looked anything other than perfectly round was through my cheap paper eclipse glasses. Maybe your ND filter just wasn't dark enough?

    Fun with AI

    That's quite a paint job! This is a screenshot from the DogmaF product page. This is what Gemini AI came up with from "paint the bike frame like a Pinarello DogmaF in Molten Sand color". It'd probably take a much more complicated prompt than that to get anywhere close.

    Fun with AI

    Ever wonder what your bike would look like in a different frame color? Original "brassy yellow". Loaded the yellow original above into my Samsung S25's image editor, hit the Gemini AI icon, then hit Create. Then entered the prompt "paint the bike frame red". Nothing else. Looks pretty good...

    Anyone good at math?

    Love those mechanical displays! San Francisco's Exploratorium and San Diego's Fleet Science Center are full of them. But totally impractical for educating millions of kids day to day. Math and science are useful and wondrous lenses on the world. They're also a useful style of careful thinking...

    Anyone good at math?

    To show how an interactive visualization can help with complicated mathematical relationships, I made an interactive graphical model of the main cycling power losses using the Desmos online graphing calculator. https://www.desmos.com/calculator/mzto8h9jho The model lets you manipulate the key...
