Ultrasport F-Bike 150 or 200B Workstation Accessory - Unused, Rare

Ultrasport F‑Bike Workstation Accessory – For F‑Bike 150 / 200B – Unused, Rare. I realised it doesn’t fit my Ultrasport F‑Bike 100, so it has not been used in actual training. Original Ultrasport accessory for turning the F‑Bike 150 / 200B into a workstation.
