Having had motor wear problems before, and reading blog posts previously about the need to
not start the motor in too high a gear,
to not stress it in high assist settings (especially up hills),
being kinder to the motor on hot summer days, cold ones too,
Put some leg into it to assist the motor!
I've come to just keep my eye on the wattage reading on the display (+ along with the above), trying to not run it too much above 300-350 watts, when I can. I'm on the heavier side, and carry loads on the bikes, so yeah, there's that.
My question is how much does the wattage read-out directly correlate to the (inevitable) motor wear? Direct correlation? Or Not? And, am I on the right track? How high a wattage is "safe risk" for a BBS02 (or) BBSHD? I know inevitably I'll need to re-grease the motor too. Thanks JNO community for any thoughts you could offer on this.
Hello, no its not a simple correlation to wattage, many more factors go into motor longevity. for example, biggest is user awareness-do they use the motor optimally (always in the correct gear, not overtorqueing, low power, use throttle sparingly, efficient use, not overheating as well so using low power on hot days and allowing cool down, keeping all gears lubricated over time). Those are the biggest factors. frankly, the wattage doesn't matter, you can run these motors. At their maximum nominal wattage and as long as they don't overheat or are damaged from misuse, they will run like a tank, bafangs anyways. With aftermarket controllers you can pump 2500 to 3000 watts+ through a BBSHD for example for 72v 'ludicrous' setups, for advanced users only. It comes down to does the user operate and maintain the motor optimally. It's worth getting to know how to program the controller as well as service the motor yourself to fine-tune performance.
