I was having a clean out and discovered an unused original Brompton saddle and a set of handlebars. These items are all you need for that shot, stuffed and mounted look, without some unfortunate creature suffering.
With the saddle facing downwards, all one has to do is to position the handlebars through, fasten it all together and then fix it to a suitable wall. I am going to put mine in my study/office at home. For mine I am going to get some wood - probably oak - and fashion some sort of plinth for the saddle to be mounted to. I have seen this done before (I think they even had one at the Brompton factory if memory serves me) and always thought that I would like one.
When I get it done I will let you know and post a photo or two. If you have already done this, please let me know and sent a photo or two.
Stay safe out there people!!
