A complete assembly that utilizes fluid pressure to actuate braking mechanisms on an electric bicycle. These systems typically include brake levers, calipers, hydraulic lines, and necessary mounting hardware for installation. Functionally, they transmit force applied at the lever through a non-compressible fluid to the caliper, which then presses brake pads against the rotor, thus slowing or stopping the ebike.
The adoption of this type of braking system offers enhanced stopping power, improved modulation, and reduced maintenance compared to traditional mechanical systems. The sealed nature of the hydraulic system minimizes the impact of environmental factors such as dirt and debris, contributing to consistent performance. Historically, hydraulic brakes were primarily found on high-end bicycles and motorcycles, but advancements in manufacturing have made them increasingly accessible for ebikes.
