A self-charging electric bicycle integrates a regenerative system, allowing the battery to replenish during rider pedaling, especially during descents or braking. This contrasts with conventional electric bicycles that rely solely on external charging. Examples include prototypes and commercially available models incorporating hub motors or specialized generators linked to the drivetrain.
Such a configuration offers several advantages. It extends the range of the bicycle, reduces reliance on mains electricity for charging, and potentially contributes to a more sustainable transportation solution. Historically, the development of these systems has been hampered by efficiency losses and added weight, presenting engineering challenges in balancing energy generation with rider experience.
