Consider this a sort of antidote to the rain that's falling and the ice-rain that's soon to be calling.
A picnic bike.
I first saw this on the U.K.-based BuzzHunt , but you know how the internet is: nobody gives attribution!
To call it a "picnic bike," might be to narrowly define a picnic as a well-lubricated, but food-reduced, stoppage on a leisure ride.
And not to be overly critical, but I can imagine that some knees and sides of legs might be tapped or scraped while riding with this inner-frame attachment. All in favour of creative ways to stay hydrated -- just not sure this is the best way.
