or what motor you have (important as some are much more forgiving than others).
It's a BAFANG M600
I have not considered the temperature of the motor. Why isn't there a temperature gauge like in my car? Where do I buy such a gauge so I don't accidently melt my motor gears?
I do think it has a thermal sensor to protect the motor, but it's nothing I would gamble on.
The M600's have made a lot of friends as a pretty durable motor, even in off road applications where they are great for their smaller size and weight, while still making reasonably good power (more than enough).
Just keep in mind the earlier warning about heating it up over a long distances at a high power setting (like 600w).
If you want to go on a longer run, slow down, keep it under 400w and you should be fine.
Most, once they get a better feel for riding an e-bike, will figure out the bike will go plenty fast enough in PAS 1 or PAS 2, while pulling well under 400w. Battery charges will start lasting quite a bit longer as well....
The M-600 I have will pull nearly 1000w at full throttle, awesome for crossing a busy road, catching up with a riding buddy, or climbing a short hill. As mentioned though, that kind of power should never be used for more than a few seconds..... -Al
