# Tricking A Bike Counter

**[Hackaday](https://daily.dev/sources/hackaday)** · 2 min read · 0 upvotes · 0 comments

## Summary

A hacker investigated how municipal bike counters work using inductive loop sensors, then experimented with ways to fool them. After failed attempts with metal pans, they discovered that wheeling a single bike wheel over the sensor and back could trick it. The final solution was a 'bike basket' — a bag containing a bike wheel — swung over the sensor twice to register a count. The post explains the physics behind inductive loop detection, including how eddy currents and inductance changes are used to identify specific objects like bicycles.
