Using the Wahoo RPM cycling speed sensor is a breeze. First, find the front wheel hub of your bike and attach the sensor to it. It's easy to do and doesn't require any special tools. Once it's attached, turn on the sensor and your smartphone or bike computer. Search for the sensor in the device's settings and pair them. Now you can start your cycling and watch the speed data on your paired device. When it comes to maintenance, keep the sensor clean by wiping it with a soft cloth. Avoid exposing it to extreme temperatures or getting it wet for a long time. If you're not using it for a while, store it in a dry place. Also, make sure to check the battery regularly and replace it when it runs low.
