Although, as you will see upthread, they also made "fixed" versions which did have to cope with torque in both directions. Point is not that the production model would be suitable for a unicycle, but that the concept is theoretically possible.
My first novel, Bridge of Otherwhere, Michael Wilkinson, on Kindle. A tale of subtle magic, mystery, friendship and love. For US$ page:
