If you want it, the best thing to do is get a compatible bluetooth tracker and use that. As a treadmill user, the kilometres metric is always wildly inaccurate, and I imagine it''s even worse on an exercise bike (which is what we call a stationary bike in the UK ). It's hard to accurately track distance without a gps connection on a treadmill, and borderline impossible on an exercise bike because how would it know how far you've gone?
Mustang, when they say "cycles" in that headline, I think they mean menstrual cycles rather than bicycles lol.
