    fun idea. bike lanes are usually next to curbs/sidewalks tho, which means they’re in the area firefighters use for their trucks and...

    i’m positive that it’s output - or at least an estimate thereof. the math aligns very closely with predicted speed and power...

    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)...

    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...

    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...

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