Not long after Akiesha 1 was published by Migros, the artist ZeMial put this piece on his website:

"What is that? What is she riding?" I asked. "It's not in the book."
"It looks like a jet monocycle." David said.
"Cool."
"Yeah, I'm going to have to use that."
So, for you ZeMial, a big thanks.
Chapter 9, Akiesha 2: Symbols in the Field:
Magee donned her E-suit. She and Akiesha exited the Beast. Magee signed for
Akiesha to switch her suit-comm to crypto and low power transmission to keep
their adversaries from detecting them. They walked around the back and
Magee opened an external compartment on the left side. She punched a button
inside the compartment and machinery extended a rack that held a strange
orange and black contraption. The thing had two wheels and looked like half
of a miniature open rover.
“What is that thing?” Akiesha asked.
“Things,” Magee said, “Two jet monocycles. The orange one is yours.”
Magee released the monocycles from the rack. The orange one seemed in
fairly new condition, the black model was older with a few dings and
scratches, and a fine coating of red dust.
“Where did you get these?”
“Black one I’ve had for a few years, orange one I bought a fortnight
ago in Marbach. I use them to scoot around a site while I’m prospecting.
It’s a lot cheaper on fuel and oxidizer than firing up the Beast every
time I want to go just a few kilometers.”
Akiesha studied her monocycle, which rested upright on its wheel and a
skid in the back. “How do I make it go?”
“Hop on the seat. Center column has the controls. Push POWER ON, then
GYRO ON.”
Akiesha followed Magee’s instructions. Lights on the control column
illuminated as she turned the monocycle on. When she activated the gyro,
the cycle stood up and remained perfectly balanced on its wheel. Magee
mounted her monocycle and switched it on.
“Controls are simple. Grab the two control sticks with each hand. Push
forward to go, pull back to stop. Let up on one stick to turn,”
said Magee.
Akiesha found the cycle easy to maneuver and was soon turning circles
spraying sheets of dust and gravel from the monocycle’s wheel.
“Whoa cool!” she exclaimed, “This is fun!”
