So is it as strong as they say?

ELECTRIC BIKE HUB MOTOR REVIEW AND COMPARISON. BAFANG, DAPU SHENGYI AND HENGTAI

The reason we conduct such test is as market is full of false claimed electric bikes and motors and sorry to say there isn’t any exception to it. Before getting into further details I need to explain some basics here.

This is not new!
Exaggerating range and power/torque ratings is something that has been plaguing the industry for sometime. It erodes credibility but E-bikes are wonderful; so the customers are willing to turn a blind eye towards it.
 
I thought I would hear from people refuting the claim but guess it's true then. Wonder how far off they are on the torque of the m600 and m620 as being 120-160nm?!

Of course it’s true and no one is surprised that’s why their not refuting it. Bafang is notorious for doing this. But people still buy their products because they like cheap things.

The only way to get get the true stated numbers out of Bafang motors is to purchase an e-bike from a boutique high-end company like WattWagons for example. The owner of WW uses Bafang motors but uses super high end controllers and this tuning can handle the high torque and wattage that the motors were designed for but failingly execute in most other brand iterations.

But unfortunately companies like WW are the exception. Almost all other e-bikes with Bafang motors fall far short of the stated wattage and torque. Also most DIY e-bikes with Bafangs and Dapu are death traps waiting to happen or garbage. My educated guess on Bafangs claimed 120NM & 160NM for the m600 and m620 are 65NM and 95NM.

My own ongoing experience with my Bafang motor that supposedly has peak 1000w at 85NM torque has led me to the conclusion that it is in fact peak 750w and 55NM torque. Speaking from experience.
