Just one question - I have always used rim brakes (as on my current e-bike). From an engineering point of view, the rim seems the most appropriate place to apply the maximum braking force, rather than on a small disc in the wheel centre. Am I missing something? Are disc brakes as effective as rim brakes?
IANAE (I am not an engineer) but it seems to me that the larger swept area of a rim brake allows for more braking force for the amount of force applied on the brake lever and also that this allows for finer braking control.
I worked this out for myself when I saw a Buell motorcycle for the first time. These have a large diameter rim mounted disc but the same principles would apply.
