Because of the many requests to build an accordion frame that I simply cannot fulfill, I have developed the frame into a kind of kit that requires very little DIY skills.
Since shipping longer frame components is very expensive, I have defined all of them in such a way that they should be procurable worldwide using the digital data available in the download.
With the new alternately arranged bar posts, the bars are held so securely that they can be held upside down. Nevertheless, they can be easily removed and replaced.
At one of the last gigs, I paid more for parking plus penalty fee, as I had exceeded the maximum parking time, than my share of the donation pot brought in. I have therefore extended my test version as a bicycle trailer. It's really fun to ride around on it. You are approached at every corner. It's definitely a good advertising medium for the gigs.
All data is available to everyone free of charge. The download link is in the video description.
By the way, the bar posts used can also be used as spare or replacement posts for wooden frames, as they can simply be mounted with two wood screws.

That is a great design…

That is a great design wyndorps. It looks very sturdy and the idea of making it bike "pullable" is very cool. In the city you could park your car in a lot somewhere close to the gig and use the bike to pull it the rest of the way.
2 questions: 1) have you pulled it around enough to experience loosening of screws or bolts? and 2) I don't see the bike trailer in the video you created. Is that available as well?
I noticed that you have removed the low-end wheels from the frame to attach the bike wheels. Do you leave the bike wheels on while you play or do you take the bike wheels off and put on the regular wheels?
The only thing you are lacking is a cover with your website and phone number painted on each side for those stops at the intersections!
Excellent!

"... In the city you could park your car in a lot somewhere close to the gig and use the bike to pull it the rest of the way. ..."
That's exactly what I am doing.
"... 1) have you pulled it around enough to experience loosening of screws or bolts? ..."
Not with the bike version, but I have been using this type of frame since 2015 and push it very often over our campus with cobblestones without anything ever coming loose. I also only have a low pressure of approx. 1.5 bar in the tires. This dampens vibrations from the road very well. I have no worries about losing screws.
"... 2) I don't see the bike trailer in the video you created. Is that available as well? ..."
I used the rear axle and the drawbar from an old children's bicycle trailer. I made matching mounts for each (see photo attached). I think there are many different trailer systems, so it makes little sense to define a fixed construction for them.
The important thing is that you should not use a coupling on the seat post due to the weight with resonance tubes and bars. This could break when braking.
"... Do you leave the bike wheels on while you play or do you take the bike wheels off and put on the regular wheels? ..."
I leave the bike wheels on when playing, as these also fix the frame well crosswise, in fact the one braked front wheel is then sufficient to fix the frame securely.
"... The only thing you are lacking is a cover with your website and phone number painted on each side for those stops at the intersections! ..."
I bought a cover, but I only use it in wet weather, because then you can't see the beautiful instrument very well.
Last week, the police stopped me and asked me if I was transporting a child's coffin. After a thorough inspection and some musical support, I was only told that I should attach a few reflectors to the sides. The proof photo then convinced me. :)
I'm glad the police let you…

I'm glad the police let you go on that one! Thanks for your answers, this is really interesting and I'll be looking at it some more.
