Loud City Labs, Bike Research
Cycling transforms cities and lives, yet our streets remain dominated by cars. We explore the science behind these stories from biomechanics to health and urban design.
About
I’m Jonathan Lansey, a data scientist, inventor, and founder of Loud Bicycle, where I’ve spent more than a decade working on car-horn-loud safety horns for bikes. My carreer connects road and traffic safety, human perception, and machine learning. This site is where I publish lightly edited, AI-generated essays that explore niche questions in safety, infrastructure, and behavior along with the occasional product review. The essays are usually drafted with OpenAI’s Deep Research or latest reasoning model. Everything here reflects my own opinions, not those of my employer Cambridge Mobile Telematics, React Neuro or Loud Bicycle.
