If the steps above do not work, you may need to update the software or use a different code depending on your manufacturer:

The implementation of an activation code aligns Speedplay with broader industry trends. We see similar mechanics with brands like Peloton (for app access), Garmin (for mapping updates), and Wahoo (for subscription features).

If you buy new from an authorized dealer, activation takes less than two minutes. If you buy used, always ask the seller to either provide the unused code or transfer the license before you pay.

The Powerlink Zero is Wahoo’s answer to the dual-sided power meter. Unlike traditional single-sided power meters, the Speedplay system measures wattage from both legs. To keep the pedal body sleek and lightweight, the "brains" of the power meter (the battery, accelerometer, and strain gauges) are housed in the spindle.
