The Beijing Great Wheel was a monument with a diameter of 198 m (650 ft) and equipped with 32 hydraulic motors and an automated boarding system.
If it had been completed, the wheel would have had a diameter of 198 m (650 ft), and each of its 48 air conditioned observation capsules would have been able to carry up to 40 passengers. Each of the 32 hydraulic motors was to have powered a planetary gearbox driving rubber tyres against the wheel's circumferential rim. An automated boarding system would have enabled the wheel to rotate continuously while passengers boarded and disembarked the capsules via electric feeder vehicles.
