Two bikes with similar watts can feel very different because of how they decide when to help.
Torque sensors follow effort
The controller interprets how hard you push the pedals. Many riders prefer the natural, proportional feel, especially when accelerating on hills.
Cadence sensors follow motion
The system senses crank rotation and applies assistance according to its programming. Some riders appreciate the easier, steady support.
The controller matters
Latency, power ramp-up and software tuning change the experience. There is no guarantee that every torque-sensor bike feels equally smooth.
What to test
Try a stop-and-go start, a gentle climb and a low-speed turn. Check whether the assistance arrives predictably and fades without surprises.
