I call these hurdy-gurdies because they are stringed instruments played by wheels (thus producing a continuous sound) and nobody seems to have given such instruments a generic name.
Some of the wheel-played instruments of Anarchestra.
Wheely-Wheely Chilmark 03
This wheel is covered with felt and plays a single string.
Bite My Crank Santa Fe 04
The uncoated aluminum wheel plays two strings, whose pitches can be altered by the two small pulleys hanging at the right.
Gurd Santa Fe 06
Four aluminum wheels driven by bike pedals play eight strings, four of which are played by a slide.
The aluminum wheeled instruments tended to screech.

One day Kino School shop-teacher Ed Davis brought his class to visit. One of the students asked what a crank and shaft arrangement was for and I told him it was for a hurdy-gurdy. He asked Ed what a hudry-gurdy was and Ed answered that it was a stringed instrument played by a leather wheel. I had read everything I could find on hurdy-gurdies and had never come across anyone using leather (traditional hurdy-gurdies have wooden wheels). Ed’s innate mechanical common sense prompted me to try leather for my wheels and I have been using it ever since. Basok was the first of these. It plays a single string and has a set of adjustable keys to effect the pitch.
Gurdiad Tucson 11
A leather wheel driven by a for pedal with two strings played by sets of keys.
Turd Tucson 11
Similar to Gurdiad, but with fretted neck.
