Hi I'm making this post to discuss and ask questions about an electric kick scooter project I would like to research and build. Ever since I first saw electric gopeds (chain transmission) and small electric hub motors, I imagined making an electric kick scooter that was almost indistinguishable in looks/function from normal small kick scooters.
Since then, many electric kick scooters have been released similar to my idea, but I would like to take it a step further. This means completely hidden wires, twist-grip for hidden throttle/electric braking, no brake levers, no display, and most importantly thinner wheels (200x25mm) each hiding a thin cogless dd motor. Not only would these things give the same size and look as a normal kick scooter, it would function the same aswell, with completely free coasting from the thin wheels/zero cogging (whether on or off).
Seeing as I'm a noob with electric motors, I'm researching to learn more about the topic, and any help or advice as I go would be appreciated as there's a lot to learn and think about. My first step is deciding what kind of motor to use.
Edit: Title and post originally focused on coreless halbach but were edited to simply focus on cogless instead after considering more kinds of motors. Also shortened to be more concise.
