There’s a limit to how much BS one can say...
i tell you with 100% accuracy there’e no class 3 ebike that will go 45kmh STEADY (as in longer then 15seconds) on a slight uphill (as in >3% ).
Class 3 as in 750watts max. No Juiced Ccx , no no St5’s , not even my BH nitro....
Or maybe you mean 1 or 2 % incline with a 30mph tailwind with a 125-145lb rider ?
Try it on a 3-4%incline, with a normal 185-275LB rider weight, prefferably pothole filled as that’s how most of the Us road infrastructure is right now. Most you’ll get is 37-39kmh or in between 20- 24mph .
Come on man... are you just trolling?! Here's an ebike segment (attached image, not the link) that I ave 28mph for 1:24 on my Stromer ST2 that already had 10,000+++ miles on it at this point (I no longer commute this way). Yes, this is a 3%+ ave grade.You can go look yourself, it's a public segment.
You'll see the Stromer was easily the fastest of the 16 ebikes and I wasn't even really trying (my HR max is 202). I weigh 200+ lbs and always carry a full load (clothes, gear, multiple tubes and tools). I also did this many times on my Focus ebike with the mid drive, rated at 70nm torque (Aventura Impulse 2.0 with 350W motor). I looked up my Focus rides and the best it ran was 23.1mph for this segment, on this commute:

People seem very confused by how torque and power works, as I was when I first went to a Stromer. I foolishly thought it was going to be slower than my Focus, because I bought into the torque specs being absolute, and thoughts of a mid-drive being more efficient. However, the motor's torque and power gets dumbed down, via the drivetrain and is VERY gear dependent. These companies seem to rate their torque by its peak, which is quite extreme. The nominal power/torque is much lower. I was initially surprised the Stromer was clearly faster, as shown in my data of the commutes. The power is right there at the wheel and constant. The only advantage my Focus has is on a super steep hill, IF I were to go super slow (<2-3mph), because I could be in a really low gear and the motor would be fine. The direct drive motor (Stromer) needs the wheel to be spinning a decent rpm for the magnets to not be cogging.
Want more examples? I'll create some ebike segments on my commutes on the hills and I bet there are many more, even better examples.
