ok so i did a lot of reserch and read through a lot of this forum. i figure im just going to get a generic motor and slowly upgrade everything. i will be using this ebike to ride to work about 9 miles from home. i can charge at work so i dont need juce for a round trip. i want speed but i also want the distance i need. what wattage motor should i go with? i had my mind set on a 48v 1000w front wheel hub. but i have no clue what kind of millage i can get on a decent battery with that motor. any tips?
