I had a chance to ride a 2022 vado 4.0 back to back with my wife's current on exactly the same 2 mile ride (a mile up, a mile down). I am a little baffled about some of my experience. Let's start with some practical stuff.
The vado seemed more comfortable in almost every way. Vibration, position, hand fatigue/numbness, rough road. All of it. The only thing I didn't like more was the seat itself. It's a bit too sporty and I definitely prefer a more cushy feeling. These were not huge differences, but they added up to more than expected when taken together. The bike felt more planted going downhill at speed on rougher road.
The baffling part: The current clearly has more power most of the time. It's jumpier when in high pedal assist. Ready to take off like a rocket. *but*, I found the vado to be the more comfortable climber on this particular climb. Now, I road my current second, so maybe I was just tired. But when climbing hard I push my current into the easiest gear and pedal assist 5. And the vado, yes, I was in turbo, but I don't think I was in the granny gear, and it still felt easier somehow. My wife commented on this as well when she got the current. She said "the other one felt easier" based on the previous model vado 4 we had rented. By contrast, on flat land, the gear ratio of the current and it's comparatively higher power let's you blast up to speed. The vado seems to rely a bit more on me to get there. Interesting.
One thing I learned, I *really* prefer CVT. Like, really. It's not close.
I am a bit concerned the vado IGH will change this equation. And I really can't test that one directly.
Any explanations why a seemingly less powerful motor would *feel* better going uphill?
