CCalcoaster replied to the thread Another new TQ motor: hpr40.If anyone hasn’t watched Yako’s canyon review with the hpr40 here’s a link. He has a couple more but this one is him testing it out on a...

CCalcoaster replied to the thread Another new TQ motor: hpr40.Yes, there has always been marketing hype involved in ratings of all kinds. That’s probably why we rarely see the actual test parameters...

CThe basic formula for torque in rotating systems is T = P / omega where, T = torque [Nm] P = power [W] omega = angular speed [radian/s]...

CCalcoaster replied to the thread Another new TQ motor: hpr40.They claim 40nm and 200 watts peak and nominal for the hpr40. The hpr50 claims 50nm and 300w peak, 250w nominal. It’s upgrade now being...

CAgain, just from press blurb, but TQ claim a system efficiency of 80% on the HPR50, and we know that the ‘40 has a few differences in...
-
COfficially it’s 90%. I’m still putting the data together from my rides, but it’s not seeming to be inefficient in terms of average...

Cwell, not really. we're talking about a specific bike - or at least a specific motor system which in a road bike means 23-30lb. not...
-
Cyes, and even 150w of assist is really quite a lot on a road bike, that's the difference between a spirited amateur and a pro in a lot...

CCalcoaster replied to the thread Another new TQ motor: hpr40.Yes, it’s logical that the hpr40 will prove to be at least as efficient as the HPR50, likely better. Besides evolving motors, there are...
