>>1324526>Modulation is mostly a concern for people who are racing through corners.Well, if you don't have Parkinson, I think you can modulate any brake relatively well.
>Shoes are a good backup in case of total failure.I had to use it not even once. It is way faster, than any sort of brake, since scooters have tiny wheels, tiny contact area, they just keep skidding.
I think scooters need something like pic related. At least ones with solid rubber wheels.
On bicycle it is different story though. Tires are air filled, and when you break, surface area on front wheel increases, which allows to brake fast without skidding.
