Its true! Magnets are not required for power and cadence when on our RevUp .206 firmware. However, they are still needed when replacing the batteries. 

  1. Be sure you are using Silver Oxide SR44 or 357 batteries. Alkaline batteries do NOT work. 
  2. After installing NEW batteries in your InfoCrank, the green LED lights will begin to flash rapidly. In order to use your infoCrank you will need to swipe a magnet past the domed module cover on the inside of your crank arm to stop the flashing light. We recommend keeping a magnet handy with your other bike tools.
  3. Once the LED light has stopped flashing rapidly, your InfoCrank is ready for use without magnets.
