mschwett replied to the thread the math of hill climbing.i’m positive that it’s output - or at least an estimate thereof. the math aligns very closely with predicted speed and power... -
mschwett replied to the thread the math of hill climbing.important distinction - 10 MPH, not 6. 6% grade. i don't know yet what it'll be at 6mph (which is more like a 10% grade, coincidentally)...

mschwett replied to the thread the math of hill climbing.here's an example with efficiency. i am missing a little motor power data at the end due to user error (the chart is a little shorter in...

I calculate motor output by seeing the terminal speed up a known grade on throttle alone. If I want to test PAS power, I ghost pedal...

mschwett replied to the thread the math of hill climbing.yep, that’s a good method if the bike goes by itself! if you need to pedal also, then of course you need to know how much work the rider...

mschwett replied to the thread the math of hill climbing.i was surprised to see (after you pointed both of them out to me) that bikecalculator seemed to diverge from gribble, but the real issue...

mschwett replied to the thread I got a big surprize.....you need a real ID or passport DOD ID card or a handful of other rare types. basically a real ID or passport. don’t bring any weapons...

mschwett replied to the thread the math of hill climbing.right, the question is are these small hub motors geared internally in a way to be efficient at, say, 6mph - which is around 75 rpm...

mschwett replied to the thread The transition.take a look at the ourworldindata link. the numbers aren’t quite that extreme, and it seems a well documented source. i agree that...

mschwett replied to the thread The transition.more questionable numbers. here are the real ones 3.2 trillion miles driven in the USA per year. this figure is widely available. a...

mschwett replied to the thread The transition.where do you get this? many different sources show wind and solar at around 15% of electricity generation, up from basically zero just...

mschwett replied to the thread Another new TQ motor: hpr40.but the bike already has BLE. it’s really just a need for / use of a standard profile for BLE. this already exists for many bluetooth...
