I was on a short trip on the weekend and wanted to have my luggage on the bike instead of carrying it on my back. (Unfortunately, I don't have a front bag yet.)
Some detailed shots of the attachment:
During my trip I realized that my legs are hitting the rod a little. I repositioned it a little further back during the tour.
To increase the stability, you can wrap the rubber straps around the rack (behind the wheel) which will increase the tension of the straps.
The idea was taken from Gianni who has a lot of great tips around Bromptons touring: https://piped.video/watch?v=vfQe4f0jbZs
Yeah, things are sometimes complicated with the rack. ๐ However, some hacks exist to increase the cargo capabilities of it.
Additional nice thing about the backpack-technique is, you can attach some bigger items vertically to the backside of the pack (between the shoulder straps). This can give a convenient location for something like a tent or a sleeping bag without interfering too much with your heels while paddling.
