Sonic bike_prototype by Darko Hanzic
"This is something that I have been working on in the last month . The first render took me about 6 hour to render the second one about 4 . It was rendered in mental ray . I wanted to do something diffrent with this one . The biker is sitting in the cabine with legs in front possition . The backwheel has a pneumatic system which flattens the back tire for better stabilization while standing . The back tire has special mechanical drive . The whole bike is designed for high speed that's why I made the back wheel larger for better grip on road"
