    star delta switch for the brushless motor

    ever wonder what it would be like to have a two speed hubmotor.
    the idea works well for ac motors but over at endless sphere it was a idea. worth testing.
    doc and i have tested it and it works well.

    you should have put want to double your speed for pennies in the title
    you and doc have in a rather short time opened up a whole new idea to ebikers
    this will catch on just a matter of time
    you are a pioneer
    nice work on the tach as a automatic switch
    you are like tim the toolman taylor only without the accidents
    keep the great vids and info coming
