Cadence works as soon as you push the pedal forward. Then the motor kicks in. Bear in mind you have 5 settings of power you have to be careful setting off in 5th from say a tight rural road junction or you'll overreach yourself. Sounds complicated but it isn't. Took me about half an hour on a quiet road to suss it all out. The 'manual' gears are pretty good to. Think cross between mini motorbike and cool looking bicycle. I can't wait for spring weather. And by the way, I am not a cyclist at all. This bikes changed all that. LolI'm not sure of the difference between cadence and torque if I'm honest. Yeah I'm semi rural atm so feel like it would be good for that plus I work in London so would be handy on a commute. Yeah I saw that video too, would just like a few more from different people to really get a feel for it. I'm usually trawling through YouTube and stuff before I buy anything
