What is one to do when stuck indoors due to bad weather or other circumstances, without the ability to ride your beloved bicycle? If you’re game designer Jelle Vermandere, you build your own cycling simulator as seen in the clip below. 

Vermandere not only created a computer simulation in Unity, but a custom Arduino Uno rig that allows him to use his actual bike as the controller.

The game features procedurally-generated maps, along with competitors using Vermandere’s own likeness scanned in as the model. When the racing begins, wheel speeds are sensed via a magnetic window sensor and steering is handled by a LEGO potentiometer rig. 

The game (without its unique interface) is playable now on your browser, while code is available on GitHub.
