Great photo - I haven't seen that in my various travels thru Cuba. I've seen the occasional local riding a modern road bike, but they're very rare. Following are a few cycling related photos that I have from Cuba.
Just like their cars, old bikes never die.
This is the most common type of "tandem" bike you'll see in Cuba.
Then there's the typical chinese bike that you'll see thousands of throughout the country.
And the local bike "parking" lot & repair shop.
I never tire of visiting Cuba - it's a wonderful country with wonderful people.
