TLDR, WTF, we need better designed ebikes or more efficient motors. I was just curious as the EV craze is pretty hype at this moment with major automakers adopting into the game. The way the EV YT channels talk and companies talk about performance and how I like to talk about it is a bit different as those channels are consumers and we are actually building the EV.
But, anyways, I found a graph of Tesla power consumption versus speed for its three flag ship cars the S, 3, and X. I then plotted my understanding of the most efficient ebike motors performance up to 100kmh (60mph) and then use the ebike calculator for the rest of the speeds (120,140,160). Note, that the Model 3 weighs on average (range variants) 3800lbs. My ebike weighs 100lbs and that is heavy.
So... At low speeds, we dont even register on the graph (see orange dots) when compared to Tesla. But, as our speed increases, our power consumption rise is not proportional to weight. I know when we ride we are like a giant flag in the wind, but even with that I mean look at this damn graph. At 100 kmh, a 3800lb Tesla is half as efficient as a 100lb~ ebike, LOL. And, its gets worse from there.
What can I say? I mean this just isnt Tesla. The EV (car) is making huge technological and design gains while electric bikes both high and modest power are in the dirt. HUH, am I doing this wrong? Am I missing something?
