On electric bicycles, regenerative braking can be used in principle. However, as of 2024 it is rarely used on bicycles, mainly because it requires a direct-drive (while many bicycles use a mid-drive motor which drives the chain), and because it cannot be combined with a mechanism. Also, the amount of energy regenerated is typically too low to be worthwhile. Regenerative braking is also possible on a non-electric bicycle. The RBSs facilitate kinetic energy recuperation through vehicle braking processes, thus avoiding the usual dissipation of energy (heat) due to friction-based brake pads. [pdf]
