Introducing Flash a bike that can move in two ways, first you peddle like any normal bike, second you can turn the throttle and the bike will move on its own. If you are going up a steep hill just turn on the pedal assist, and fly up that hill. Flash is a modern bike with a rechargeable battery that can go up to 50 miles on a single charge. With a top speed of 28 MPH you can be on time anywhere. Flash even has an alarm mode to alert the owner if someone is taking it.
Flash relates to engineering because engineering is about failing a first, but then eventually getting it. The creators of Flash probably had to try many different rechargeable batteries, before finding one that fits and makes the Flash able to go up to 50 miles on a single charge. Flash comes equipped with lights in the front and back to alert any cars on the bikes presence.
