It had 2 bars out of 5. I rode it around 40 minutes and killed it dead.
This is a 350 watt direct drive, quite a bit less than the one I am proposing to build. it does assist OK, but is pretty meager on straight motor. I don't care about that except as a measure of what it can do.
My ride in to work is primarily downhill, it is the trip home that would leave me sweaty. |
If it was mostly depleted then the voltage and power were down too, so that's worth thinking about in terms of the power the motor could deliver.
If you go direct drive, get a motor controller and throttle that can do regen, then. You have long hills to work, so lots of your braking could be with regen during the commute in. Would be fun to see how well it works for you.
