Ok
Flat ground with headwind, same power;
There is a difference between Eco and Tour but interestingly there is virtually no difference between Tour eMTB and Turbo - it’s when I put the power down that I can differentiate.
Putting power down in Tour;
It responds.
OK .. but ........
Maybe better explained as ...
Ride in Eco .. What does that feel like - as in RIDE in eco (pedal meaning pedal to move the bike, rather than just turn your legs around)
Ride in Turbo .. What does that feel like.
Ride in EMTB mode .. what does that feel like.
At this point you should now feel like : pedal in Eco, I get assistance, though only about the same as a mouse running on my back wheel.
I ride in Turbo, I pedal - but don't have to pedal very hard and it feels like the mouse has been swapped for 1000 mice and there's a lump of cheese stuck up my arse they want.
I ride in EMTB mode, it feels like there's several mice, but when I pedal hard my shorts move and the cheese is exposed and dozen's more mice jump on the wheel and join in.
Now test Tour.
If it feels like there's several mice when you pedal and if you pedal hard, there's still just several mice - then you have "Tour".
If it feels like there's just one mouse, but when you pedal hard there's several hundred mice and you exposed your cheese again - you have Tour+
