Source export-ready acoustic warning devices, CNC machined components, and cockpit accessories engineered for urban fleets, sporting distributors, and European importers.
Impact-type resonant chime engineered with anodized rain-resistant alloy. Delivers 105dB crisp acoustic warning tuned to pierce European automotive cabin insulation.
IPX6 sealed housing with 360-degree rotation base. Features a quick flip latch designed for rainy commuter routes and cobblestone shock absorption.
Aerospace-grade CNC aluminum alloy construction. Eliminates chain drops across gravel pathways, pump tracks, and aggressive urban single-speed setups.
High-strength 45mm reach cockpit stem machined from 6061-T6 aluminum. Delivers maximum steering precision for heavy-duty trekking and cross-country cycling.
Infrared motion-sensor activation with dual-beam optical distribution. Ideal for nocturnal maintenance, commuter cycling visibility, and low-light winter riding.
Dual-rail clamp compatible with smart radar tail lights and action cameras. Secure structural rigidity engineered against pavé road vibrations.
6 sealed cartridge bearings, high-engagement 120T ratchet system, QR/thru-axle modular end caps. Built for torque transfer on demanding e-hybrid bikes.
Precision CNC anodized aluminum shell housing silicon nitride ceramic balls. Minimizes rotational drag while shielding internal bearings from road grit.
In-depth engineering analysis examining acoustic wave propagation, climate resilience, and compliance under French Traffic Code (Code de la Route R315-3) across Hauts-de-France.
The urban core of Lille presents unique acoustic challenges characterized by narrow historic corridors, cobblestone paving (such as Vieux-Lille), and mixed-traffic tramways alongside the Ilévia transit network. Traditional low-frequency brass bells often fall short of cutting through ambient traffic decibels exceeding 75 dBA.
Harke’s piezo-electric acoustic transducers generate sound frequencies in the critical 2.8 kHz to 3.5 kHz bracket. This frequency range triggers instantaneous auditory localization for pedestrians and motorists without exceeding French municipal sound limits or inducing panic in pedestrianised zones.
Operating in Hauts-de-France requires robust protection against prolonged oceanic moisture, high autumn humidity, and winter de-icing salt application along municipal cycling arterial highways (Vélopole). Inadequate sealing in standard horns leads to internal PCB oxidation and switch failures within six months.
Our bike horn assemblies employ double-chamber ultrasonic plastic welding and silicone gasket barriers rated to IPX6. Internal electronic switches are conformally coated against condensation, while external mechanical fasteners are fabricated using 304/316 marine-grade stainless steel or anodized 6061 aluminum alloy.
With the exponential expansion of speed pedelecs, long-tail cargo bikes (Vélos cargos), and corporate bike fleets across the Lille metropolitan hub, integration with onboard electrical systems has become paramount. Mechanical bells are legally required, yet electric horns are critical for heavier, faster micro-mobility vehicles.
Harke manufactures stand-alone rechargeable battery-powered horn systems as well as DC-DC step-down integrated units capable of wiring directly into 24V-60V e-bike central batteries (compatible with Bosch, Shimano, and Bafang drive protocols). Units strictly align with CE, RoHS, and French Code de la Route Article R315-3.

Founded in 2019 in Shenzhen, China's core electronics and lithium engineering hub, Harke Technology delivers factory-direct dependability with streamlined supply chains.
Every production run passes incoming component inspection, automated acoustic decibel verification, and rigorous waterproof submersion checks prior to export container loading.
Our dedicated European export division maintains a 97.41% response rate with documented technical feedback, CAD file reviews, and quote delivery within four working hours.
From custom acoustic circuit IC design to laser-etched European brand logos, Pantone silicone molds, and localized multilingual packaging for retail-ready shelf displays.
Lower entry barriers for specialized bike ateliers and regional French distributors: sample orders from single SKUs, trial batches from 10–50 pieces, and mixed-SKU container stuffing.
Offering comprehensive Incoterms including FOB, EXW, and door-to-door Delivered Duty Paid (DDP) into warehouse facilities across Hauts-de-France, handling customs duty, VAT clearance, and lithium battery declarations.
Direct answers addressing compliance, distribution logistics, and product customization for European wholesale buyers.
Yes. Under Article R315-3 of the French Traffic Code, cycles must be equipped with an acoustic warning device capable of being heard at at least 50 meters. Our devices deliver compliant tones in dual-mode configurations (a gentle warning chime for shared pedestrian-cycle lanes and a 120dB horn for automotive roadway encounters).
All Harke lithium-rechargeable electric horns and smart lights possess current UN38.3 test reports, MSDS documentation, and CE safety certificates. We routinely ship air cargo and maritime sea freight under DDP terms directly to warehouses across Lille, Roubaix, and Tourcoing with zero customs clearance delays.
For stock finished products, wholesale orders start at just 10 pieces. For custom laser engraving of brand logos or custom silicone strap colors, MOQs start as low as 200–500 units depending on the model. Bespoke injection-molded casings or customized circuit boards start at 1,000 units.
Yes. Our engineering and design team provides full dieline templates for customized cardboard retail boxes, eco-friendly blister-free packaging, French/English instruction booklets, and pre-printed European Article Numbers (EAN-13 / UPC) ready for scanning in retail chains.
