Iranian designer Mohammad Ghezel presented his unique vehicle concept that cross combine the principles of car and motorbike. Dubbed eRinGo, the vehicle moves on a large wheel running around its axis, with two medium sized wheels on either side to support the vehicle on sharp curves.
When idle, the wheels extend to provide balance and support to the vehicle. The eRinGo comes built-in with rotor/ gyro system, balancing the car on the single wheel with ease. What make this concept design unique is that it provides steering wheels for both passengers.
