An electric scooter for the elderly with a long-lasting cycle endurance system includes: an electric scooter for the elderly； an interactive power supply system, wherein the interactive power supply system includes, a solar power source, a first voltage stabilization amplifier circuit, and an amplifier circuit , Which is mainly supplied to a second DC generator, a battery charging circuit, and a lithium iron battery charging source； a C-SW control circuit that controls a C-SW switch ON / OFF state, where the C-SW control circuit is in When V1 <；4.8V, the C-SW switch is in the ON state. At the same time, the lithium iron battery is started and the supply of a first DC generator to generate the V2 power source is started. The voltage is then stabilized by a second voltage stabilization amplifier circuit. The amplifier circuit continues to provide the second DC generator power source； if the C-SW control circuit is at V1>； 4.8V, the C-SW switch is OFF, and the battery charging circuit turns on the lithium iron again. Battery continuous charging mode； a charging base, which is continuously powered by the second DC generator to continuously supply circulating power for the elderly electric scooter.一種具長效循環續航系統之老人電動代步車，包括有：一老人電動代步車；一交互供電系統，其中該交互供電系統包括有，一太陽能電源，一第一穩壓放大電路、一放大電路，主要供應予一第二直流發電機及一電池充電電路、一鋰鐵電池之充電源；一C-SW控制電路，控制一C-SW開關ON/OFF狀態，其中該C-SW控制電路於V1<；4.8V時，該C-SW開關即處於ON狀態，同時啟動該鋰鐵電池並開啟供應一第一直流發電機產生V2電力來源，並藉一第二穩壓放大電路穩壓後，再由該放大電路持續提供該第二直流發電機電力來源；若該C-SW控制電路於V1>；4.8V時，該C-SW開關即處於OFF狀態，該電池充電電路即再次開啟該鋰鐵電池續行充電模式；一充電座，主要由該第二直流發電機不斷電循環電力持續供該老人電動代步車之循環電力。
