In all essence a KT controller is as close as one can get to a mid drive TS system, to me a TS crank for a hub makes little sense as it is acting as speed control.

KT has instant startup and instant stop.

The big pluses for me from it were a) start up when you are in the wrong gear / hill starts, the motor kicks in pretty instantaneously that you apply pressure to the pedal - this is the only time I would need a throttle b) you can ghost pedal to change down gears when coming to a stop without the motor kicking in - this is the only time I would need brake sensors c) simplicity of installation - don't need brake sensors or throttle ( and d) it is current control rather than speed control, which is unusual in UK based kits with UK support)

From customers point of view, torque systems help them lose weight. You will see average battery use per kph is lower with torque system because you can pedal as much or as little as you like, overtime you will probably pedal less not more.

It's simple physics: For any given journey, a certain amount of work needs to be done to complete it. That work comes from a combination of work from the rider and work from the electrical system. You can divide it up how you like, but if you use less energy from the battery, it's because you did more work yourself.

 

If you have a torque multiplying system, you can't pedal as much or little as you like. You have to pedal with torque to get the torque multiplied, and if you want to go up a hill, you have to increase your pedal force. It's the extra work you do on the pedals that causes the motor to not have to do as much work, which gives the illusion of those systems being more efficient, and why you're more likely to lose weight with such a system if you have a tendancy towards laziness.
