Final Poster

The client has requested a device that can replace the battery of an electric derailleur (an electronic mechanism for shifting gears). The device should consist of a small battery and solar cell and be mounted onto the bike so that it will not be disruptive to riding or storing the bike. Ideally, this will eliminate the need to charge the battery. Existing charging solutions for these batteries are expensive and require removing the battery to charge it before a ride. Our solution will solve those problems by not requiring an expensive external charger and passively charging the battery while riding.
