       I invent "durable electric bicycle". The high function electric bicycle which was not possible. Its object from students to the elderly. People don't need power to pedal because it is entirely electric. So, it play an active part for elderly whose legs weaken, for students who have big loads after a closing ceremony, for homemakers who go to the supermarket to buy food. Its shape is bicycle, so it doesn't violate school regulations, and people don't need a license. People can use it semi permanent because it is durable. Variations of color are abundant, and price is not expensive. People charge in the middle of the night, people can use it next morning. IT will be a great hit!
