//TODO - demonstrate the Bicycle Class - you will need to create the Bicycle class
// Note the Bicycle class returns 2 and implements the getETA and getDirection
//TODO - demonstrate the Drive Class - - you will need to create the Drive class
// Note the Drive class returns 1 and implements the getETA and getDirection
