Born to be wild? But with a ring like this, how could it be anything else? 

1. The adjustable ring comes on a silver stainless steel base with a circumference of 3 cm.
2. The sphere covering the ring is made of smooth glass and reveals a miniature biker at its centre, dressed in a red helmet and black overalls, riding his vintage-style red and chrome motorbike. He seems to be driving at top speed, as can be seen from his position at the front of the car, braving the wind! What fantastic places can he be heading for on this smoky anthracite tarmac covered in fresh paint?  The rest of the story is up to you.
