    Front Hub motor for Sun EZ-1?

    Hello everyone,

    I'm thinking of getting a front hub motor for my Sun EZ-1 SC.
    This is a 16" inch wheel.
    (a rear motor won't work because I plan to get an Extrawheel).
    How many volts and watts should I get?
    I'd like to be able to ride at least 6 hours per charge @ 20mph.
    Also, should I get a casted hub or a spoked hub? I'm thinking of a casted hub (with built in hub motor) because it will not need to be respoked or trued. (goldenmotor dot com sells one with a built in controller available with either a spoked or a casted rim [any experience with this model?]).
    Do you have any front rack battery mount suggestions (or will a front rack even be compatible with my bike)?

    Thank you so much. I look forward to hearing from you.

    No real knowledge but I had an EZ-1 sx and while killing time in a forum the 16 inch wheel was thought to be a real speed reducer.
    Good for torque but cutting top speed by a considerable amount..

    Something to consider.

    I did convert my EZ-1 to a 20 Inch front wheel using the fork off the EZ-Sport. To avoid cutting the Sports slightly longer neck I shimmed it.
    It worked well and did what I wanted, bending the fork to correct additional extreme wheel flop was simple. It was about a 3" ark placing the
    Axle point between 2 and three inches forward of the original pos...

    Many factors to consider doing this... A 'Mid Drive system' will let you use all the cassette gears for even MORE speed and power, Yes the Mid drive would be more complex and expensive, But as with most things In Life, 'You Get What You Pay For'
    Is Mid Drive worth the money ?
    For Flat land riding, probably not,
    For Hill climbing power, being able to down shift that power for a steep hill, also for all out performance/speed, possibly, speed cost money, Say 3 times the cost of a basic Hub drive system...

    Then I moved on to this:

    After applying the EZ-1 money to this like new used (50 miles IF that)Tour Easy LE model I was in the TE $450.....
    And Sold my like new 6 year old EZ-1 for more than I paid for it new
    They were only $500 back In 2007

    My EZ-3 stock and how I will go Electric with it one day:

    OP, Hang your batteries under the seat for better handling....

    20 MPH with the 16 Inch wheel,, gonna take more volts,, 48 I would think
    a 20" wheel hub motor combo could probably do 20 on 36 volts

    a geard motor right ?
    48 Volts and 600 watts In a 20 Inch wheel got this man 26 mph....

    So you could hit 20 with a 16 Inch wheel, maybe...

    Look Into this stuff below, lots of tech there..

    There is an Electric Bikes subforum here on BF. Might get some other useful feedback there.
