The first bike is formative for tho whole biker life. If the first experiences on a bike are to rumble on a knockmobile, hoping that bike not to fall to pieces and by the way learning to ride without crashing into trees or cars, than riding bikes won't be a pleasure at later times. But with a fancy bike to be proud of, equipped with front and coaster brake, a stabiliser for the first tries they have got all they need to learn riding and loving their bike.
