I am not sure if anybody else has had the same problem? I have found that there is only one possibly suitable stand from a well-known manufacturer that works on the back axle only (and not braced with the a chainstay (that is non-existent on the Fujin and other similar lowracers). But it simply doesn't work because the torque is too great for the rather pathetic cogwheel arrangement they put in. I have written to the manufacturers for help (as I think it is actually a design fault as I can't see that it would ever work on any bike) to no avail.

However, a master-blacksmith has done a good job of making a plate to adapt the same stand - images, hopefully on the links below.  Now he has worked out how to do it he would be happy to supply others with the same thing. I said I would let interested parties know. If anybody is perhaps they could DM me (is that possible?) or respond to this
