A project called Deck de France, built by sukolupo, maps live telemetry from standard Bluetooth bike trainers to a virtual gamepad, then pipes that input into a Steam Deck mounted directly to the handlebars.
The input surface of a bike trainer is narrow: cadence, resistance, and steering cover the basics, but sukolupo's mapping is functional enough to run Rocket League and the Tour de France game series. The full GitHub repository details which trainers are supported and how the virtual controller bridge is constructed, and that implementation is where the real technical weight of this piece sits.
This sits alongside prior esoteric controller builds like a functional trombone mapped to Trombone Champ and a purpose-built horse-riding controller. What makes the original worth reading is the specific data pipeline from trainer firmware to Steam Deck input layer, not just the novelty.
