This was The World's Largest Working K'nex Ferris Wheel from 2008 to 2011. It measures 12 feet in diameter and 13 feet tall. It has 128 spokes, 32 carts and about 12,000 pieces. It was designed by myself (Austin Granger) and was built in 3 weeks (including repairs made after wind damage) by myself, Renee Bergeron, Sam Ihlenfeldt, Stephen Walker, Simon Olson and Paul Davis. The wheel is supported by a quarter-inch steel axle and powered by a 12 volt DC motor. The wheel was completed thanks to the generous donations of over 4,000 pieces from people in my neighborhood.

Includes a POV shot of a camera riding in one of the carts.

Interesting side-note, this wheel is so heavy, yet so perfectly balanced that removing even a single gondola will throw the center of gravity off to the extent that the 12v motor can no longer power the wheel.
