    I normally work from home. If I don't, my company's office is about 20 miles away. A train travels all but a few miles of that distance so the most convenient commute ends up being bike-train-bike.

    A 12v 250w system is not comparable to a 48v 500w system. but the watts are the important part.

    If you are using this on a tandem with two riders while going uphill, that will draw a lot of power. Would make sense if the battery is dropping below the "low voltage cutoff" in those conditions
