    Dual Hub Motor Front and Back

    Was thinking about a bike with a hub motor in the front wheel and a hub motor in the back? Does this require 2 separate controllers and throttles? Could you use the motors regen as a front and back brake? By having two motors can you reduce the motor size like instead of one 96v you could use two 48v?
    Has anybody ever done this?

    I was googling and could only find dual Hub rear or dual Hub front.

    You can do it with a single throttle and two controllers.

    Yep, you can. You can dial the two controllers to have different levels of regen too.

    I'm not aware that anybody has done it no, but for pretty good reason - with 4 motors, I expect you'd like to be able to travel at a reasonable rate of knots yes?

    Such being the case you may wish to take a look into the effects of unsprung mass on the handling characteristics of motorcycles.
    [spoiler alert] - unless you're planning on going exclusively in a very straight line on a very smooth surface, I don't think you're going to like it.

    which isn't to say that the project won't be fun, merely that you needn't expect anything practical to come from it. ;-)
