Package Contents

Before you begin, please check the contents of your package:

• 1 x CYCPLUS C3 Sensor (can be configured for speed or cadence)

2. Setup and Installation

Battery Activation

The sensor comes with a pre-installed battery, but it needs to be activated:

1. Locate the protrusion on the battery cover. Push it towards the center position and then gently open the battery cover.
2. Remove the transparent insulation spacer from the battery compartment.
3. Reinstall the battery cover, ensuring the protrusion aligns with the center position.
4. Press the battery cover firmly until it clicks into place.

Mode Switching (Speed or Cadence)

The CYCPLUS C3 sensor can operate in two modes: Speed or Cadence. You can switch between modes by rotating the battery cover:

• Speed Mode: Rotate the battery cover until the sensor emits a blue light.
• Cadence Mode: Rotate the battery cover until the sensor emits a green light.

Important: One sensor cannot measure both speed and cadence simultaneously. If you need both metrics, two sensors are required.

Installation for Speed Measurement

To measure speed, install the sensor on your bicycle's wheel hub:

1. Ensure the sensor is set to Speed Mode (blue light).
2. Attach the curved rubber pad to the bottom of the sensor.
3. Securely attach the sensor to the front or rear wheel hub using one of the provided rubber bands. Ensure it is firmly in place and does not interfere with other bike components.

Figure 3: Installation of the sensor for speed measurement on the wheel hub.

Installation for Cadence Measurement

To measure cadence, install the sensor on the inside of your bicycle's crank arm:

1. Ensure the sensor is set to Cadence Mode (green light).
2. Attach the flat rubber pad to the bottom of the sensor.
3. Securely attach the sensor to the inside of your bicycle's crank arm using one of the provided rubber bands. Ensure it is firmly in place and does not interfere with pedaling.

3. Operating Instructions

Sensor Activation

After installation, rotate the wheel (for speed mode) or the crank (for cadence mode) a few times. The sensor's indicator light will flash for 10 seconds, indicating it is active and ready for pairing.

Pairing with Devices

The CYCPLUS C3 sensor supports both Bluetooth and ANT+ protocols for versatile connectivity.

Bluetooth Connection

To connect to a smartphone app or Bluetooth-enabled device:

1. Ensure your smartphone's Bluetooth is turned on.
2. Activate the sensor by rotating the wheel or crank until the indicator light is on.
3. Open your preferred cycling application (e.g., Zwift, Wahoo Fitness, Strava).
4. Within the app's sensor settings, search for and connect to the sensor.

• The Bluetooth name for Cadence mode is CYCPLUS C3.
• The Bluetooth name for Speed mode is CYCPLUS S3.
• The sensor can only be connected to one Bluetooth device or app at a time. To switch devices, disconnect from the current one first.
• When using a smartphone app, search for the sensor within the app itself; searching via your phone's system Bluetooth settings is usually ineffective.

ANT+ Connection

To connect to an ANT+-compatible bike computer or device:

1. Activate the sensor by rotating the wheel or crank.
2. On your ANT+-compatible bike computer, navigate to the sensor pairing menu.
3. Search for new sensors and select the CYCPLUS C3 when it appears.

• The sensor can be connected to multiple ANT+ devices simultaneously.

Indicator Light Meanings

• Blue Light Flash: Sensor is in Speed measurement mode.
• Green Light Flash: Sensor is in Cadence measurement mode.
• Red Light Flash: Battery power is less than 20%.

4. Maintenance

Battery Replacement

The CYCPLUS C3 uses a standard CR2032 coin cell battery. When the red indicator light flashes, it's time to replace the battery:

1. Push the battery cover's protrusion to the center position and open the cover.
2. Carefully remove the old CR2032 battery.
3. Insert a new CR2032 battery with the positive (+) side facing up.
4. Reinstall the battery cover, ensuring the protrusion aligns with the center position, and press firmly to seal.

Cleaning

Wipe the sensor with a soft, damp cloth to remove dirt or sweat. Do not use abrasive cleaners or solvents.

Water Resistance

The sensor has an IP67 waterproof rating, meaning it is protected from dust and can withstand immersion in water up to 1 meter for 30 minutes. It is suitable for riding in rainy conditions, but avoid prolonged submersion.

5. Troubleshooting

• Sensor not connecting or dropping out:
  • Check the battery level (red light indicates low battery).
  • Ensure the sensor is active by rotating the wheel or crank.
  • Verify the sensor is in the correct mode (speed or cadence) for your intended use.
  • For Bluetooth connections, ensure no other device is currently paired with the sensor.
  • When using smartphone apps, always search for the sensor within the app's settings, not your phone's general Bluetooth settings.
• Inaccurate speed readings:
  • Ensure your bicycle wheel size is manually entered correctly into your bike computer or cycling application. The sensor does not auto-detect wheel dimensions.
• Brief disconnections during rides:
  • Some users report brief, infrequent disconnections, but the sensor typically reconnects quickly without significant impact on data. Ensure the sensor is securely mounted and free from obstructions.

7. User Tips

• The CYCPLUS C3 sensor is highly accurate and easy to pair, significantly enhancing your cycling workout by providing reliable speed or cadence data.
• It offers quicker response to accelerations compared to GPS-based speed measurements.
• Users report excellent battery life, often lasting for months of daily rides on the factory battery.
• The dedicated mode selector (rotating battery cover) helps prevent confusion between speed and cadence functions, unlike some models that rely on button presses and LED colors.
• It pairs smoothly and reliably with a wide range of devices and apps, including Garmin Edge series, Apple Watch, Wahoo, Strava, MyWhoosh, and Zwift.
• The sensor works effectively with indoor trainers, connecting reliably to popular training applications.
• For accurate speed readings, always remember to manually enter your bicycle's wheel size into your bike computer or cycling application.
