No, Equilab uses the GPS and sensors in your mobile device to track your trainings, including your gaits while riding. (For Premium users riding with their Apple Watch standalone without a phone, gaits are not recorded given the watch does not have the necessary sensors to detect gait.)
You can learn more about how Equilab works by reading the articles How does Equilab measure the gait? and Where should I keep the phone while riding?
Additionally, Equilab does not offer any physical sensors and is not associated with any company that offers them.
