    Electric trailer with drill brake?

    i found this pic,and i cant figure out what the drill is for.

    i though it could be for chainging gears on the left wheel or a brake system, but i dont see a derailleur or calipers for a brake.
    it has a battery,motor some sort of controller


    Any ideas?

    I think it's for a turbo boost.

    Maybe he's using the drill as a generator?
