Acoustic-Triggered Smart E-Bike Chain Waxing System
This intelligent maintenance bot uses a piezo sensor to detect the specific vibration frequencies of a dry chain and automatically applies wax lubricant. It ensures peak drivetrain efficiency and silence without the rider ever needing to check a maintenance log.

Original prompt
Bike chain auto-luber. Mounted to your e-bike rear triangle, it senses chain noise via a piezo against the chainstay and meters a few drops of dry wax lube onto the chain when noise crosses a threshold. Reservoir holds two months of riding. Phone notif when low. ESP32 plus a peristaltic micropump.
