I have the Crosscurrent, which is basically the same as the Ripcurrent but without fattys. I don't know about "switching" between the torque and cadence sensors, my understanding is that it has both and they both operate in tandem, not one or other. What I can tell you is that the torque sensor is VERY well tuned on my Crosscurrent. I recently got to compare it to an Aventon Level.2 and while Aventon has a very polished product, I prefer the power and performance of my Crosscurrent - Aventon's torque sensor is not nearly as "analog" feeling. Aventon's feels like it has "steps" of power addition based on pedal torque, while Crosscurrent is a smooth addition/removal of power on pedal torque.

EDIT: Though in terms of quality, Aventon is "higher end" - Juiced focuses on power and performance but their frames are very basic (e.g., the Level.2 has rear brake lights integrated into the frame and fender, the fender is metal not cheap polystyrene plastic that breaks the first time the bike flops over, etc.). I still prefer my Crosscurrent to the Aventon Level.2, even if it's a lower tier of frame.
