    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.

    The wobble probably has something to do with the geometry of the bike. If that's true there isn't much you can do beyond what you already know-- relax your hold on the handlebars if that works......

    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

    I am not a lawyer. For a proper interpretation of the law, speak to a lawyer.

    With that said, I do not think your bike is legal for ON ROAD use. You can sell it on craigslist but you should inform...

    I thought you are asking if you should buy a 48v motor even if you are set on a 36v battery. There is probably no benefit to using the 48v motor unless you match it up to a 48v battery.
