i dont quite get how it works.

can someone please explain it really slowly for me.

is the left crank not attached to the hub at all?


The hub is different than any other unicycle hub. The hub body is on
bearings and is able to rotate around the axle. In that sense the hub
is like a bicycle wheel hub that spins on an axle.

The cranks are attached to the axle. There is a jackshaft (the two
cogs above the hub). The chain from the cranks drive the jackshaft.
The second chain from the jackshaft then goes down and drives the hub.
So the hub is able to spin at a different RPM than the axle. That is
what allows for gearing. It can be geared up or down based on the size
of the cogs.

I hope that makes sense. It's hard to explain without pictures.
