Bicycle Electronic Horn with 110dB Sound for 50-Metre Visibility

This bicycle electronic horn delivers a 110dB sound that carries up to 50 metres, ensuring cyclists are heard in urban environments where traditional bells often go unnoticed. The compact 94mm by 44mm by 33mm black PC plastic unit mounts easily to standard handlebars, providing reliable auditory alerts without adding significant weight or bulk. Unlike mechanical bells that depend on proximity, this electronic horn maintains consistent volume regardless of distance from the listener, making it particularly effective on busy roads, shared pathways, and during group rides where multiple sounds compete for attention.

Features and Construction Quality

The bicycle horn incorporates several specific design elements that contribute to its performance and durability. From the impact-resistant housing to the consistent sound output mechanism, each component has been selected based on measurable performance criteria relevant to cycling safety applications.

Compact Handlebar Design

Measuring 94mm in length, 44mm in width, and 33mm in height, the horn maintains a low profile that doesn't interfere with brake levers, gear shifters, or cycling computers. The symmetrical shape allows installation on either side of the handlebar, while the black finish blends with most bicycle components. This specific dimension ensures compatibility with handlebars ranging from 22mm to 32mm diameter without requiring additional spacers or adapters.

110dB Sound Output

The electronic mechanism produces a consistent 110dB sound measured at 1 metre distance, which translates to approximately 90dB at 10 metres and 70dB at 50 metres - sufficient to be heard over typical urban background noise of 60-70dB. Unlike mechanical bells whose volume decreases with distance, this electronic horn maintains its acoustic characteristics throughout its effective range. The sound frequency of 2.8kHz falls within the range where human hearing is most sensitive, ensuring maximum perceptibility.

PC Plastic Durability

Constructed from polycarbonate plastic with an impact resistance rating of 125J/m at 23°C, the housing withstands accidental drops from handlebar height without cracking. The material maintains dimensional stability between -20°C and 80°C, preventing warping during seasonal temperature changes. Black pigment is integrated throughout the material rather than applied as a surface coating, ensuring the colour remains consistent even if the surface becomes scratched through regular use.

Practical Cycling Applications

This electronic horn serves multiple specific purposes across different cycling scenarios, from daily commuting to recreational riding. Its consistent performance addresses particular safety challenges cyclists encounter in various environments.

Urban Commuting Use

During morning and evening commutes through city centres, the 110dB sound alerts pedestrians stepping into cycle lanes, drivers opening car doors without checking mirrors, and other cyclists approaching from blind spots. The consistent volume proves particularly valuable at traffic lights where engine noise masks traditional bell sounds, and in construction zones where background machinery creates high ambient noise levels exceeding 80dB.

Recreational Path Riding

On shared recreational paths where pedestrians, dogs, and children may move unpredictably, the horn provides advance warning from up to 50 metres away - approximately 10-15 seconds at typical cycling speeds. This allows ample time for others to acknowledge your approach and move aside safely. The distinct electronic sound differentiates from natural environmental noises more effectively than mechanical bells that can blend with other metallic sounds in park settings.

Group Cycling Versatility

During group rides where multiple cyclists need to communicate hazards or intentions, the consistent 110dB output ensures messages reach all riders regardless of their position in the peloton. The sound carries effectively through wind noise that often masks voice communication at speeds above 25km/h. Riders at the back of a 20-person group approximately 50 metres from the front can still hear alerts clearly enough to respond appropriately to changing conditions.

Measurable Safety Benefits

The bicycle horn provides specific advantages that contribute directly to cycling safety and convenience. These benefits translate into practical improvements for regular cyclists across different riding disciplines and environments.

Long-Term Value Proposition

With no moving mechanical parts to wear out and weather-resistant PC plastic construction, the horn maintains consistent performance through years of daily use without requiring maintenance beyond occasional cleaning. Compared to mechanical bells that often lose volume as springs fatigue or mechanisms clog with dirt, the electronic design provides reliable operation throughout its lifespan. The initial investment translates to approximately 0.5p per day over three years of daily commuting use.

Enhanced Riding Satisfaction

The confidence of knowing your presence will be acknowledged reduces the mental load of constantly anticipating whether others have noticed you. This allows greater focus on traffic conditions, road surfaces, and navigation rather than worrying about being overlooked at intersections or pedestrian crossings. The simple button activation requires minimal thumb movement, maintaining hand position on handlebars for better control during alert situations.

Immediate Safety Upgrade

Installing this horn provides an immediate measurable improvement in auditory visibility, increasing the distance at which others become aware of your presence from the typical 5-10 metres of mechanical bells to the full 50-metre range. This additional warning time proves particularly valuable when approaching blind corners, cresting hills, or navigating areas with limited sight lines where early auditory signals prevent collisions before visual contact is established.
