Bicycle charging speaker horn compact 110-120db 3-mode USB rechargeable with rubber strap mount

This electronic horn replaces a standard bicycle bell with a significantly louder sound output and multiple alert tones. At 110-120db, it provides clear audible warnings in traffic, on shared paths, or in busy urban settings. The separate wired switch keeps the controls within easy reach while the horn itself mounts forward on the handlebar, reducing clutter. A Li-polymer 280mAh battery powers the unit, charged via the included USB cable, supporting up to 2000 horn rings per full charge. Water splash proof construction offers basic weather protection for everyday riding, though the unit should not be submerged.

Features and Construction

The TWOOC T-002 combines a loud electronic horn with a practical wired switch setup, offering three sound modes for different alerting needs. Its compact, lightweight build clips onto the handlebar tube using a rubber strap, requiring no tools to install or remove.

Material and Build

The horn body is constructed from durable plastic with a water splash proof rating, meaning it can handle light rain and road spray but should not be immersed. The switch wire is spiral-shaped with a range of 15-30cm, providing flexibility in switch placement on the handlebars. Total weight is approximately 40 grams, adding negligible mass to the bike.

Size and Practical Fit

The horn fits handlebar tube diameters of 22-31.8mm, covering most standard bicycle handlebars. The wired switch mounts separately and fits tube diameters of 18-24mm, such as thinner bars or stem sections. The forward-facing horn mounting minimises handlebar space usage, leaving room for other accessories.

Uses and Placement

This electronic horn is suited for cyclists who need a louder, more distinctive alert than a traditional bell. It works well on commuter bikes, city bikes, and touring setups where traffic awareness is critical.

Event or Professional Use

Cycle couriers, security patrols, or event marshals can use the siren mode to attract attention in noisy environments. The trumpet mode offers a short, sharp blast for quick alerts, while the whistle mode provides a sustained tone. The 2000-ring battery capacity supports multiple rides before recharging is needed.

Everyday Home Use

For daily commuters, the horn provides a louder warning than a bell, useful for alerting pedestrians, other cyclists, or vehicle drivers. The USB rechargeable battery eliminates the need for disposable batteries, and the tool-free rubber strap mount makes it easy to swap between bikes or store when not in use.

Benefits and Buying Value

The key advantage of this product is its combination of loud output, multiple sound modes, and rechargeable battery in a compact, easy-to-mount package. It offers practical safety functionality without needing tools or permanent installation.

Reuse and Low Maintenance

The Li-polymer battery can be recharged hundreds of times via USB, and the splash-proof construction reduces the need for drying or special care. No batteries to replace, and the rubber strap mount is simple to clean and maintain.
