Bicycle Horn DUNLOP 21 cm Chrome — Hand Pump Air Horn, Dunlop 147178

The DUNLOP 21 cm Chrome Hand Pump Air Horn is a handlebar-mounted audible warning device designed for urban and recreational cycling. Constructed with a chrome-finish metal horn and a rubber hand pump, it delivers a clear, strong sound that helps alert pedestrians and other road users. The horn mounts to most bicycle handlebars and is intended for commuter, city and leisure bikes where a compact, manually operated signaling device is preferred.

Advantages

The chrome housing offers corrosion resistance and a polished appearance while the rubber pump provides simple, reliable manual operation without batteries. Its 21 cm length produces a distinctly loud tone suitable for city streets and bike paths. The unit is lightweight and compact, enabling easy installation on standard handlebars and minimal interference with riding position. Maintenance is low: the mechanical design requires no electrical components and can be kept operational with routine cleaning and inspection.

Suitable for

• Commuter bicycles used in urban environments
• City bikes and hybrid bicycles for everyday riding
• Leisure and recreational cycling on paths and parks
• Situations where a manual, battery-free warning device is preferred

How to use

Mount the horn on the handlebar using the supplied clamp or mounting bracket, positioning it within easy reach of your hand while maintaining safe control of the bicycle. Squeeze the rubber pump firmly to force air into the horn and produce the warning tone; repeat as needed to gain attention. Inspect the mounting hardware periodically to ensure the clamp remains secure and check the rubber pump for cracks or wear that could reduce performance. Avoid directing the horn directly at people at very close range to prevent discomfort.

Usage recommendations

Use the horn as a short, clear audible signal to warn pedestrians and other road users. For safety and compliance with local regulations, combine the horn with appropriate visual awareness—ride predictably, use lights in low visibility, and signal changes of direction. Store the bicycle indoors when possible to minimize exposure to moisture and prolong the chrome finish and rubber pump life.
