“I am constantly looking for ways to naturally improve performance and overall enjoyment when riding my bike. The GO² device is not only backed by impressive data, but more importantly, I just feel better during and especially after my rides”


Third Place at Tour de France, Olympic Silver Medalist

"I used it on second half of my run leg, and my heart rate went down and pace got faster. It was pretty amazing!”


Professional Triathlete (taken from IM 70.3 race)

"I felt less out of breath and was able to catch my breath much quicker when I used the GO². I felt better, my average heart and max heart rate were lower during the periods where I used the GO². I was astonished by the initial results and am truly excited about the potential of this device.”
