Hi all, just joined the forum this evening hoping someone can help me out…
I am reasonably new to Zwift and have question regarding the speed and distance calculations that are occurring.
My setup is a road bike on a JetBlack M1 Pro (NON smart trainer).
I have the following sensors:
Wahoo Tickr arm/wrist HRM
Wahoo RPM Speed Sensor (mounted rear wheel hub)
Wahoo RPM Cadence Sensor (mounted left crank arm)
I am saving to buy myself a ‘smart’ trainer, but using my current rig to see if I’m going to enjoy this whole experience enough to justify the expense.
Now, I understand that I am riding a non-smart trainer so there is no feedback through my trainer regarding resistance or incline/decline information, but when Zwift is reporting that I’m riding a fairly flat road (2-4%), and I’m doing 70-80 rpm as reported by my cadence sensor (which I believe) on my big chainring, and my 11 tooth rear sprocket, Zwift is reporting that I’m doing no where near the speed that I would be on the open road.
As an experiment to see if my sensors are working properly, I collected data from a ride in the generic Wahoo Cycling app with the same bike, same sensors. It took me 2:30 to ride 2km’s at approx 88-90rpm which works out at an average pace of 47.4km/h - this relates to what I’d expect out in the real world.
So my question,
Why is Zwift changing my reported speed when I’m NOT on a smart trainer?
Why doesn’t it just report the actual speed that my sensors will be giving it?
It’s quite disheartening to be working so hard for so little ‘reported’ effort. 25mins to do 8km’s on my fastest gearing at 70-80rpm? Something not right there…
Any help on this would be greatly appreciated!
