★ Fan lore — unofficial & written for fun

Genie occupies a rarefied position in the RoboPacer lineup. At 3.7 W/kg she's only accessible to riders who have genuinely committed years to cycling — not just months of consistency, but the kind of training history that shows up in your power curve. Her group is small and quiet, mostly serious amateur racers and dedicated enthusiasts who treat the indoor trainer the same way a professional treats the velodrome. Genie doesn't welcome you. She tolerates you until you prove you belong.
