[Photo group] Norwegian extreme artists perform balancing stunts

Eskil, Norwegian extreme artist. Ronningsbakken uses his exquisite balancing skills to push human endurance and concentration step by step to the limit. Whether he is performing a near-naked "reverse cycling" on the steel wire on either side of the cliff, or standing upside down on a bicycle with a big front wheel and a small back wheel at the top of the cliff, Roningsbakken's technique is nothing less than walking on a knife edge.
