This Public Bike system looks like a hamster bike to me. This public bike system is meant to cater the address of problems faced by tourist visiting Berlin. It allows tourists to tour the parks and other tourist destination. This innovative rental bike runs on two wheels which turn independent of each other though the seat holds the wheels in position and the bike is propelled forward by pedals which are used in straight movement. The handles aid in braking and steering and a personal touch has been added by the designer by providing space for luggage. Overall the bike can be termed as a perfect companion for those who wish to explore the city !
