I have found this information incorrect (I apologise!) Wahoo and Garmin both rely on the built in GPS if no other related sensors are present!Interestingly, both Garmin Edge and Wahoo Element bike computers rely on sensors. For example, a Wahoo speed sensor is a necessary buy for a traditional bike, with the Wahoo power meter as a nice extra. Specialized and Giant e-bikes with ANT+ already have the appropriate sensors.
