How much of the time are ebikes run at full throttle?
It's a serious question, not asked frivolously.
Every data sheet I've seen, lists the power, amps, torque, RPM, efficiency etc. only with full throttle applied. And they only list data at the motor's highest RPM range, usually 300-400 RPM or more for direct-drive hubmotors.
I've only ridden an ebike for a few minutes at a dealer here in San Diego, so I have little real experience as a commuter or whatever. My own ebike project is stalled, awaiting delivery of the 48V 20Ah battery from China.
Those of you who commute regularly on your ebikes, once you get started, do you just hold the throttle wide open (mostly on flat ground) and let the ebike run at its max speed? Or do you back off on the throttle a little, and run at maybe 20mph even though your ebike can do 30 on flat ground?
For people who back off a little, the motor's performance at full throttle might not be as important as its performance at part throttle. How efficient is it at, say, 20mph at part throttle? If that's where you do most of your riding, that becomes the most important question, doesn't it?
Do most ebikes in real usage, do most of their running at full throttle? Or at part throttle?
