Pannier rack for larger diameter seat post I have recently purchased an old, second-hand folding (or at least collapsable) bike, a Daewoo shuttle to be precise. In order to use it for commuting, I would like to fit a pannier rack onto it. It has very small wheels (16") and so I was thinking of a seatpost mounted rack, preferably with quick release. Unfortunately, the seatpost diameter is quite large (about 35mm, maybe a touch more) and the one rack I bought (https://www.amazon.co.uk/gp/product/B01DUAMLDA) didn't fit because of the seat post diameter being too large. 

I have searched everywhere for a pannier rack that fits large diameter seat posts, but have drawn a blank. Can anybody suggest any pannier rack that would fit or any tips or tricks to make a standard pannier rack fit onto a large diameter seatpost?
It's probably 36&nbsp;mm; that seems reasonably common. Most seatpost racks go up to 31.8&nbsp;mm

Taking 36&nbsp;mm as a guess makes searching much easier: it's an upper limit for some models:

It seems easier to find a trunk bag attachment for such a large post. There is such a thing as a Rixen &amp; Kaul KLICKfix Caddy Post and Bar Clamp 2016.  That would allow you to mount a handlebar bag on the seatpost, or this Vaude mount is designed for their trunk bags but could be used with other things.  None of these are of much help if you want to choose a pannier to suit you.

Traditional style racks do exist, such as this Atran Velo Luggage Carrier Active Seatpost (which seems to have curved sides, but many panniers would still fit, and it's quick release). The search that turned up that last one (and the Vaude) was seat post rack "36mm" -rixen
