The CydeKick is a bicycle accessory system that charges your phone by generating power while you pedal. It is the only fully integrated, self-powered, add-on system that can do this without introducing additional friction, meaning less resistance than other add-on devices. Hub Dynamos are another type of generator on the market which technically add no friction either. Standalone, these generators cannot charge USB devices without aftermarket electronics to condition/clean the power. Additionally, Hub Dynamos require rebuilding or replacing your entire wheel. All said and done, the cost of the Hub Dynamo, the conditioning equipment, and the assembly labor (assuming you don’t buy an entire new wheel) can add up very quickly! The CydeKick is a fully integrated system that includes everything required to accomplish charging your USB devices. It’s also easy to install and compatible with almost all conventional bicycles.
