OEM Backlit Odometer Bicycle Speedometer – Custom Factory Solutions
This product line supplies OEM manufacturers with a compact, backlit speedometer that integrates speed sensing, distance accumulation, and optional cadence or pulse outputs. The unit is designed for direct installation on bicycle frames, e‑bike assemblies, or fitness equipment where reliable, low‑power measurement and clear visibility under varying lighting conditions are required.
Technical Overview
The speedometer uses a Hall‑effect sensor triggered by a magnet mounted on the wheel hub or crankshaft. Each pulse is processed by a low‑power MCU to calculate instantaneous speed (km/h or mph) and cumulative distance. A transmissive LCD with LED backlight provides readability in daylight and night‑time conditions without external illumination.
Key Specifications
| Parameter | Typical Value |
|---|---|
| Supply Voltage | 3.0 V – 5.5 V DC |
| Operating Current (backlight off) | <2 mA |
| Backlight Current (LED, white) | 5 mA – 15 mA (adjustable) |
| Speed Measurement Range | 0 – 120 km/h (0 – 75 mph) |
| Odometer Range | 0 – 99999 km (roll‑over) |
| Update Rate | 2 Hz (speed), 0.2 Hz (odometer) |
| Operating Temperature | ‑20 °C – +70 °C |
| Ingress Protection | IP65 (sealed housing, connector) |
| Display Type | Transmissive LCD, 7‑segment, 2‑line |
Design and Material Considerations
The housing is molded from UV‑stabilized ABS with a polycarbonate window to resist impact and scratching. Internal PCB uses FR‑4 with conformal coating for moisture resistance. The Hall‑effect sensor is sealed in a rubber grommet to prevent water ingress while maintaining accurate magnetic coupling. Cable options include PVC‑jacketed or TPE‑overmolded variants with strain‑relief boots.
Customization Options
- Backlight colour: white, amber, red, green (LED wavelength selectable)
- Display units: km/h, mph, or dual‑mode switchable via firmware
- Mounting styles: handlebar clamp, frame‑integrated bracket, or adhesive‑backed pod
- Cable length: 150 mm – 800 mm with optional coiled or straight configurations
- Connector types: JST‑PH, Molex Pico‑Lock, or custom over‑molded plug
- Firmware parameters: pulse‑per‑wheel‑rev scaling, odometer preset, sleep timeout, backlight intensity
- Optional outputs: analog voltage proportional to speed, reed‑switch pulse for external cadence sensor
Quality Control and Testing
Each unit undergoes functional verification at three temperature points (‑20 °C, 25 °C, 50 °C) to confirm speed accuracy within ±2 % and odometer drift <0.5 % over 10 km. Housing sealing is validated by IP65 spray testing and immersion cycling. PCB assemblies are inspected via AOI and functional ICT before final programming. A sample of each production lot is subjected to 500 h accelerated life testing (temperature humidity bias) to ensure long‑term reliability.
Typical Applications
OEMs integrate this speedometer into city‑bike, mountain‑bike, and e‑bike models where a low‑profile instrument cluster is preferred over larger digital dashboards. The same core is used in stationary fitness bikes and rehabilitation equipment because the Hall‑effect sensor tolerates high‑vibration environments while maintaining low power draw, extending battery life in sensor‑only configurations.
Frequently Asked Questions
| Question | Answer |
|---|---|
| Can the housing dimensions be altered? | Yes. The outer dimensions are defined by the mold; changes require a new tooling quote and are evaluated based on volume. |
| What information is needed for a quotation? | Required inputs: expected annual quantity, desired backlight colour, units, cable length/connector, mounting method, and any custom firmware settings (PPW, sleep timeout). |
| Which materials are available for the housing? | Standard is UV‑stabilized ABS with polycarbonate window. Alternatives include glass‑filled ABS for increased rigidity or PC‑ABS blend for higher impact resistance, subject to MOQ. |
| How is product quality verified before shipment? | Each batch receives 100 % functional test, 10 % visual inspection, and a statistical sample for environmental sealing and life‑cycle testing as described in the QC section. |
| What packaging options are offered for export? | Units are packed in anti‑static trays, placed in corrugated cartons with foam corner protection. Cartons are sealed with humidity‑indicating desiccants and labeled for CE/FCC compliance. Palletization available upon request. |
| What is the typical production lead time? | Lead time ranges from 4 weeks for standard configurations to 8–10 weeks for projects requiring new mold or custom firmware, assuming approved artwork and material readiness. |
