What a research paper on bicycle stand design. You go into depth on any subject! Thoroughly enjoyed seeing the various designs and my favourite one is number 4 - the one with yellow paint. Thanks for sharing.@kus-knee.
Upvoted.
Update at my end is that I have started doing a Photospeak series on my Africa memories. Letting the picture speak instead of writing a lot of words. I would be honoured if you take a look at Photospeak #1 and #2 and provide your valuable comments. Thanks.
