Train Horn For Bike

Engineered Performance & Practical Safety

BossHorn’s train horn for bike pairs a high-output air compressor with real metal train trumpets and a custom control PCB that delivers three selectable volume levels, motor overheat protection, and battery deep-discharge protection. The system works with 15+ major cordless tool brands, runs off a compatible battery, and includes a wireless remote that reaches up to 2,000 feet. Hand-assembled in the USA, it’s built to give unmistakable presence while protecting the motor and battery during repeated use.

Everyday Use Cases & Sensory Details

The train horn for bike brings a crisp, throaty blast that cuts through traffic noise—ideal for urban commuting, crowded bike lanes, or calling attention on mixed-use trails. No mounting or wiring: attach a compatible tool battery or buy a kit with one included and you’re ready. Expect instant responsiveness, a metallic trumpet tone, and the confidence of being heard during group rides or emergency stops.

Portability, Innovation, and Why It Matters

Want a train horn for bike that you can trigger from across the park?

We built the original cordless drill-powered train horn so you don’t have to compromise volume for portability.

Every unit uses genuine components from real cordless tools because durability matters on the road.

Our custom PCB gives selectable volume and protects the motor and battery—so it’s loud when you need it and safe when you don’t.

BossHorn products are hand-assembled in the U.S., and that hands-on approach shows in fit and finish.

We make it simple: no vehicle mods, just grab a battery and go.

Portability is the third key factor here—after audibility and reliability—so BossHorn focuses on a compact package, quick battery swapping, and a lightweight footprint that fits onto handlebars or stays stowed in a pack, while still delivering a bold, metal-trumpet tone.
