Disc brakes are the best type of electric scooter brake because they are lightweight, easy to maintain, provide strong braking power, and perform well in wet/dry conditions. Disc brakes are mechanical (cable-controlled), semi-hydraulic, or hydraulic. When hydraulic, the brake lines are pressurized with fluid, which allows you to engage the brakes with minimal physical effort. Drum brakes are also effective and lower maintenance than disc brakes as they are completely enclosed in the wheel hub; however, they are less effective when overheated and their performance is subpar of disc brakes. Lastly, foot brakes tend to perform poorly, especially in wet conditions. They are becoming less and less common on modern electric scooters.
