CycleOps PowerTap Speed or Cadence Sensor

Yes, but not simultaneously with a single unit. You can configure one sensor to track speed by mounting it to the wheel hub, or cadence by mounting it to the crank arm. If you want to track both metrics at once, you will need to purchase two separate sensors.

It likely will. The sensor features dual-band connectivity, meaning it broadcasts via both ANT+ and Bluetooth Smart. This allows it to pair with almost any modern cycling computer, GPS watch, or smartphone cycling app.

Instead of relying on a magnet passing a reed switch, this sensor uses an internal accelerometer. It detects the rotational movement of the crank arm or wheel hub to calculate your speed or cadence data with high precision.

Installation is straightforward and tool-free. The low-profile design includes flexible mounting options that allow it to strap securely to most crank arms or wheel hubs without interfering with your bike's frame or drivetrain.

The sensor provides approximately 200 hours of ride time on a standard CR2032 coin cell battery. Replacing the battery is simple and requires no special tools; you can easily pop the cover off to swap it out when needed.

Yes. The unit is rated IPX7 for water resistance, meaning it is fully protected against rain, road spray, and puddles. You can ride in wet conditions without worrying about damaging the internal electronics.
