The DUH dropout system looks awesome! Who can pull strings and get Surly to sell these to frame builders? Am I correct in thinking that they used to sell some small components to builders?

The new avinox launch with the cylindrical battery got me kinda excited since Iāve been thinking of doing an ebike version of the lugged frame, but have been waiting on a good cylindrical battery option.
I guess MOQ on those units could be quite high though and getting the 3D models might be impossible for small builders. If anyone has any info on that it would be appreciated.

You should post up if you find a cost/ supplier for those! I was thinkingā¦ it would be cool if someone released a structural battery that would work as a down tube. Could reduce size and weight even more. Something like z-couplers on the ends.

Go with MAHLE X20. Send me a message if you want more info.

Not a structural battery, but a fine solution I agree. Batteries inside tubes makes more sense with aluminium because the material properties lead towards a larger-diameter thicker-wall tube anyway. But Reynolds have made it work with steel and the Mahle batteries.
As for a āstructural batteryā Iām not sure thereās really any such thing. It would just be a battery inside its own piece of tubing. Batteries are naturally quite flimsy things.

In Reynolds, we have develop a DT and dropouts for MAHLE X20. In steel and Ti. As I said before, drop me a message for more information. So far the builders have given a good response and some beautiful bikes have been made.

More the idea that the battery itself has a case, and that case could be made structural, instead of batteries in thier case, wrapped in down tube.

You could of course. But there are some downsides. You would want to paint it the same colour as the bike, which means youād have to try and match the colour if you ever replaced the battery. I also wouldnāt like leaving my bike locked up outside my hotel without a downtube in case somebody bashed into it or sat on it or something and bent the unsupported main triangle.

Hereās a fun one.
My colleague got tasked with converting a wheelbarrow into a trailer. He settled on a BOB-style attachment method and whipped this up.

Some time ago I did a weekend hand lettering course with Jeff Marshallā¦ the control, experience, and confidence required to make good looking simple strokes is insanely high. Very unforgiving.
It was a great weekend! Itās good for the soul to learn new things and be humbled every now and then.

Absolutely. Some of the other crafts when you look into them have insanely skilled artisans. Blows me away at what some people can do.

Hey I did an interview with Art Trapotsis, host of the New England Endurance Podcast and itās ready for prime time! Hereās a YouTube link. Itās also on Spotify and Apple streaming. Note nearly everything in the reel is framebuilding-centric.
