The Cyr wheel is an acrobatic device invented and popularized in the early 21st century. It consists of a single large, metal hoop, and is used in a similar manner to a German wheel, with the acrobat rolling the wheel around the stage from the inside.

The Cyr wheel was popularized by Daniel Cyr in 2003.

There are records of others using a similar apparatus during the 19th and 20th centuries, but Daniel Cyr is known to have popularized it, and claims he created it without any awareness of previous similar devices. It is now used in performance by hundreds of performers around the world.

Here is a rare picture of "Adalbert von Rekowski" dated around 1930 using a similar device.
