That's not a standard usage for "duty cycle". Normally duty cycle is supposed to mean the percentage of time that a PWM controller is in the "open" state. When the gate is open a lot you have a high percentage of the voltage passing through to the motor and it's said that you have a high percentage duty cycle number. In a hyper-simplified simulation with a fixed gear they are more or less related, but not on a geared bike.
The way you are using "duty cycle" you're thinking in terms of what percentage of time that "in operation" the rpms are at peak power or some other rpm. So you're creating a source of potential confusion. :?
What is the real name of the "operational duty cycle" if that phrase is incorrect?
Anyone?

There are two types of people on this forum. There are those that use hub motors and there are those that use chains along with some type of gearing. The "bottom line" is that for the same power output from a given motor the geared bike can span a range of roughly double it's fixed gear counterpart. So the "high low" of hill climb verses top speed means you get twice as much out of the same motor with gears. On the flip side, you can use a hub motor and then simply double the voltage (and power) and get more or less the same result. Both are illegal in most places (depending on your local laws for motor power and acceptable top speed) so it's up to you how you want to break the law if that's what you had in mind. (mine does 40 mph on the flat with a 1000 watt motor)
I like gears myself... it allows me to use a smaller motor and when it comes to a hill I simply slow down and gear down rather than go for the "Big Iron" hub motor and high voltage to force my way though. The police seem to like the idea of a small motor being used with gears. (at least they seemed to like it when I showed it to them)

I liked the oxymoron-ish "(actual paraphrase)" part -- I suppose that's like a verbatim paraphrase?
