'Frequently changing or removing the battery is inconvenient to the rider' – Giant Bicycles files patent for self-charging power meter
Giant's patent application looks to offer an interesting solution to cyclists' increasing frustration around electronics on bicycles
Giant Bicycles has filed a patent for a self-charging power meter, addressing the inconvenience of frequently changing or removing the battery in traditional power meters. The self-powered apparatus in the pedal consists of a generator and an energy storage element, which purportedly eliminates the need for a battery. The generator, featuring a stator and a rotor, creates torque as the cyclist pedals, generating DC power that charges the energy storage element.
The patent states that this self-charging system would provide a more convenient solution for powering low-voltage devices such as power meters. Although Giant has not yet confirmed the commercialization of this invention, the patent represents a potential step forward in reducing reliance on battery charging for bike electronics.
Giant's sponsorship of professional cycling teams suggests that this technology may be tested on future road bikes.
