I think my favourite is two cyclists riding in parallel, holding a wooden pole at shoulder height with a third person hanging by their feet from said pole.

That one's not in this selection of photos http://www.theguardian.com/environment/bike-blog/gallery/2013/jun/13/edwardian-stunt-bikers-in-pictures?picture=410604207#/?picture=410604848&index=16 but some of the others are.

I quite like the idea of the jousting though!
