My dad is a biker through and through!
Approximate size is 3 ft. long by 18 inches high (see http://www.cakeswebake.com/photo/harley-cake-full-size?commentId=4635016%3AComment%3A975154&xg_source=msg_com_photo ). The entire body area of the bike (saddle bags, rear and front fender, engine area, headlight section, and tank) are all made of cake and edible. The seat was made of wood to screw into a central dowel for stability and support. The exhaust pipes and forks are PVC covered with fondant and painted with silver airbrush paint, the handlebars were made the same way, but with thinner copper tubing. Front tire is wood, windshield is plastic. The saddlebags are decorated with silver dragees for studs, the logo on the tank was freehand with buttercream, and the engine was painted on the black fondant by hand with edible silver airbrush paint.
