Bulk Universal Handlebar Mount Bicycle Speedometer

This unit attaches to the handlebar via a adjustable clamp and measures speed by counting pulses from a magnet mounted on the front wheel. Its design allows a single part number to accommodate handlebar diameters from 22 mm to 32 mm and various mounting angles, reducing inventory complexity for high‑volume OEM orders.

Technical Specifications

Applications

Original equipment manufacturers benefit from a universal mount because it eliminates the need for multiple bracket variants across different bike models, streamlining assembly lines and reducing spare‑part overhead. Aftermarket distributors can stock a single SKU that fits city, mountain, and e‑bike handlebars, simplifying logistics. Fleet operators use the device for speed monitoring in maintenance programs, where reliable, low‑maintenance sensors lower total cost of ownership.

Material Options

• Housing: UV‑stabilized ABS, impact resistance > 30 kJ/m²
• Clamp bracket: Stainless steel 304, tensile strength ≥ 520 MPa
• Sensor shaft: Hardened steel, surface hardness HRC 55
• Gasket: EPDM rubber, compression set ≤ 5 %
• Lens: Polycarbonate, UV‑stabilized, V‑0 flame rating

Customization

Cable length between sensor and display can be adjusted from 150 mm to 500 mm to accommodate varying frame geometries. Laser‑etched logos or part numbers are available on the housing surface. Firmware calibration can be set to specific wheel circumferences (range 1500 mm–2500 mm) for precise speed read‑outs without user adjustment.

Quality Control

Each unit undergoes a functional test where speed pulses are simulated at 5 km/h, 20 km/h, and 40 km/h to verify display accuracy within ±0.5 km/h. Ingress protection is validated by spraying water at 12.5 L/min from a nozzle for 3 minutes while checking for moisture ingress. Vibration resistance is assessed per IEC 60068‑2‑6, sweeping 10 Hz–500 Hz at 2 g for 30 minutes per axis. Final inspection includes a visual check for clamp surface defects and LCD uniformity.

Packaging

Bulk shipments are packed in anti‑static trays holding 50 units each, stacked in double‑wall corrugated cartons measuring 400 mm × 300 mm × 200 mm. Cartons are sealed with pressure‑sensitive tape and marked with handling symbols for fragility and moisture protection. Palletized loads receive stretch‑film wrapping and corner boards to prevent shifting during transit.

Frequently Asked Questions

• Can the handlebar clamp be adapted for non‑standard diameters? Yes, custom inserts can be machined to fit diameters outside the 22 mm–32 mm range; please provide the exact measurement for a quotation.
• What information is required before a price quote? Required details include order quantity, desired cable length, any branding or marking specifications, and preferred delivery schedule.
• Which materials are available for the housing? Standard is UV‑stabilized ABS; alternatives such as polycarbonate or glass‑filled nylon are available upon request for higher temperature or impact requirements.
• How is product quality verified before shipment? Each batch undergoes functional, ingress protection, vibration, and visual inspection as outlined in the quality control section.
• What packaging options exist for smaller orders? For quantities under 500 units, units are packed in recyclable cardboard boxes with internal foam dividers; larger orders use the bulk tray system described above.
• How are export shipments protected against corrosion? All metal components are passivated, and the entire package includes a desiccant pouch and a vapor‑corrosion inhibitor liner inside the carton.
