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
