What is Weasel Wes Cycling Simulator?
Weasel Wes is what happens when indoor training meets a 2D platformer: hook up your smart trainer or sensors and ride through a procedurally generated side-scrolling game world instead of a rendered French valley. It connects over ANT+ and Bluetooth, controls trainer resistance including proper ERG mode, and uploads finished sessions straight to Strava.
The economics are the point. It's a one-time $1.99 on Steam (the site's framing is "cheaper than a fancy coffee") in deliberate contrast to subscription platforms. Worth knowing that price is an Early Access price: the developer says on the Steam page that it will go up gradually as features land, so it's cheapest now. There's also a free demo on Steam, and the developer says any added hardware support goes into the demo too, though not all content and features do, so you can check your trainer connects before paying. It runs on genuinely modest hardware (integrated graphics, 2 GB RAM), works offline, and has been in Early Access since 27 October 2025, built by a solo developer under the name PzenQ.
Key Features
Real sensor support
Power meters, speed and cadence sensors, and heart rate monitors over ANT+ or Bluetooth, with trainer resistance control.
ERG and non-ERG workouts
Structured workout modes with resistance control; the developer's tested trainers so far are the Elite Suito and Wahoo Kickr Core. Patches have since added target power for Tacx Flux S trainers and untested support for Saris/CycleOps target watts and resistance modes, with broader hardware support planned through Early Access.
Custom workout editor
Build your own structured workouts and training progressions inside the game.
Platformer world
Sessions play out in a 2D platforming-inspired world with procedurally generated content and unlockables, driven by RNG seeds.
Strava upload
Completed rides and workouts upload directly to your Strava account, the only part of the game that needs an internet connection.
Who It's For
- Budget-minded indoor cyclists priced out of subscription platforms
- Riders with older laptops: the minimum spec is a decade-old i3 with integrated graphics
- Anyone who finds virtual-world realism less fun than an actual game
What platforms does it run on?
Windows only (Windows 10+, 64-bit), distributed through Steam. No Mac, mobile, or console versions.
Do I need internet to play?
No. It's fully offline single-player. Internet and a Strava account are only needed for the optional activity upload.
Which trainers work?
Any ANT+ or Bluetooth device providing power, cadence, speed, or heart rate should connect. Resistance control is supported; the Elite Suito and Wahoo Kickr Core are the developer-tested pairings so far. A January 2026 patch added untested support for Saris/CycleOps target watts and resistance modes. The free demo on Steam is the easy way to check your own setup.
What does Early Access mean here?
It launched into Steam Early Access on 27 October 2025, and the developer's estimate on the store page is "about 12 months or less". As of 13 October 2026 it is still in Early Access, still at $1.99. The roadmap includes expanded hardware support, artwork and music improvements, character customization, and more unlockables. The $1.99 is expected to rise as that work lands.
