No, you can not compare torque numbers of a mid drive torque and hub directly to come to a conclusion because there is a translation between the motor and the rear wheel in the mid drives (the drivetrain). Power is what makes you move (and Stromer is significantly more powerful unless the speed, hence its rpm, drops too low at which point mid drive will shine) use it instead and you will not be confused. Let's not turn this into another hub vs mid drive. All these topics have been discussed many times on the forums. If you have further questions/comments you should continue in those threads.
Please your argument is like I am right let's not discuss it anymore!!! LOL! Stop it! Just stop! You are not right and I will not concede to your point! Granted I did say that
A. the Stromer would be faster on the flats than the Creo and HP.
B. Almost all hub motors would be faster than the equivalent mid drive motor.
C. It is a single gear ratio motor. It is meant to rotate up to a certain point. Stromer has the 44 newtons to do that.
D. A electric motor can rotate faster than a human pedaling. It works independently of the bike gearing and pedaling.
but we are discussing power as in torque not speed (quit confusing the two)
E. One
newton equals a force that produces an acceleration of one meter per second (s) per second on a one kilogram (kg) mass.
F. The Creo and HP have more newtons
G. Mid-drive motors are known for higher performance and torque when compared to a similarly powered traditional hub motor. One key reason why is that the mid-drive motor drives the crank, instead of the wheel itself, multiplying its power and allowing it to better take advantage of the bike's existing gears.
H. Small hub motors do not have the torque for inclines like mid drive motors. Those hub drive ebikes that you see plowing up the hills need massive battery packs and are much larger compared to a mid drive motor.
But lets make it simple, we can compare two of my FAVORITE cars to get a conception. The (Stromer) 2019 EcoBoost Mustang and (HP) 2015 VW Golf Sportswagen TDI. Both have 4 cyl,
the 2019 Ford Mustang EcoBoost 310 hp @ 5500 rpm / Torque 320 to 350 lb-ft / 0 to 60 - 5.1 seconds
2015 VW Golf Sportswagen TDI 150 hp @ 3500 rpm / Torque 236 / 0 to 60 - 9.0 seconds
If you want to say the Mustang is faster based on that criteria then you would be correct in thinking that the Mustang is more powerful but that is not the full picture and what is being discussed
When we are discussing power (
momentum,
gravitational force, speed and efficiency) lets use a hill and weight (towing). When towing a trailer of any size, you need enough engine torque to get it launched from a stop, including uphill, and enough power to keep it moving at reasonable speeds up long, steep grades and to safely pass on two-lane roads. You need sufficient engine and driveline cooling to avoid overheating coolant or lubricants up long hills and in hot weather and sufficient brake capacity and cooling to safely descend long downhill grades.
Manufacturer specification for the 2019 Ford Mustang EcoBoost towing capacity is 1000 pounds
Manufacturer specification for the 2015 VW Golf Sportswagen TDI towing capacity is 3500 pounds
Here is a truer picture of which car is more powerful if not based on purely speed!
Bottom line, a slim rider about 150 lbs on a Stromer will beat my 6ft 3in 222 fat ass pounds on a HP on a flat street to 28 mph all day long
But.....
Given as the incline become greater and you add the power of the pedaling and shifting in the right gears then the power of the mid drive shines through!
That Stromer is one impressive bike and is efficient! You pay so much for the technology, features and that sophisticated hub motor. For a commuter biker and /or bike touring, the HP and Creo pales in comparison in that regards but like the VW that is not where the strength lies! For riding up any hills where motor and human power acts as one is where it shines!
Now you can say the conversation is through
