Showcasing the bike as a symbol of movement and freedom on two wheels is inked by many people who have embraced the biker lifestyle. The image of a biker with a flaming head wearing sunglasses and riding a chopper is a good tattoo idea. A cross with a snake coiled around and the words 'Die in Heaven' emblazoned on it, makes for a good design. Showcase the blueprint of an engine surround by interwoven long flowing lines across your shoulder. Another idea is to have the handle bars and head light of a bike done in dark shading on your back. If you want you can get your bike manufacturers logo done in a tribal theme on your body.
