Terminology alert!

Direct drive is like a conventional unicycle, or penny farthing, where
the cranks are attached directly to ends of the hub spindle/axle.

Track race bikes are "fixed wheel" which is where there is no freewheel
mechanism, and the rider has to pedal all the time, but can use back
pressure to slow down.

"Direct gearing" might be used to describe a machine where the gear
ratio is 1:1 - i.e. front and back cogs are the smae size.

So, a unicycle, penny farthing or circus bike 9as sold by unicycle.com
is direct drive.

A giraffe unicycle or a track bike is usually fixed wheel.

Some giraffe unicycles and some rare bicycles are "direct geared".
