About Adrienalin Limited
Adrienalin Limited is a UK company at the start of building something genuinely new at the intersection of live-service gaming and real-world fitness. We incorporated in May 2026 and are currently in the R&D phase.
The problem we are solving
Home fitness has a motivation problem. Pre-recorded classes solved the scheduling problem. They did not solve the reason people actually show up to a spin class: a room full of people, an instructor who knows your name, and a shared experience that only exists in that moment.
We are building a platform designed around live sessions — classes that only exist while they are running, hosted by real instructors, experienced inside a multiplayer game world that reacts to your effort. If you miss the class, you missed it.
What we are building
The platform connects FTMS-compatible smart bikes to a live-service multiplayer world built in Unreal Engine 5. Freelance spin instructors host classes. Participants join from home and ride alongside each other inside the world. Cadence, power, and resistance all stream live.
Mobile is the primary target platform. The product will also run on PC and console. Because FTMS is an open Bluetooth standard, any certified smart bike works without proprietary hardware.
Where we are now
We are at the beginning. Adrienalin Limited was incorporated in May 2026. The team is currently in the R&D phase, scoping the technical architecture and preparing grant applications to fund the initial development. No product exists yet.
This website exists to establish the company's presence, share our thinking as we build, and make it easy for press, investors, and future instructors to find us.
Why Unreal Engine 5
UE5 gives us the rendering quality and real-time networking infrastructure to build a world that responds to live data from many FTMS devices simultaneously — and ship it to mobile without compromising the experience. The Nanite and Lumen systems in UE5 make the visual fidelity achievable on hardware that previously could not support it.
The business model
The platform will run on a SaaS model. Riders pay to access live classes. Instructors earn per session with the platform taking a fee. There is no hardware lock-in, no pre-recorded content library to maintain, and no studio overhead. The product lives or dies on the quality of live sessions.
