Loud City Labs, Bike Research
Cars dominate our streets, making cycling dangerous. While better infrastructure is the best solution, cyclists need immediate ways to protect themselves. This site explores not only long term solutions but also short term solutions to dramatically improve bicycle safety until our cities catch up.
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.
