It's friggen HUGE
West U. Cycles, Inc., owner Jeff Nielsen (5'8") presents Houston Rockets center Yao Ming (7'6") with a custom-made Gunnar Rockhound 29" wheeled mountain bike Friday morning, Feb. 25, 2005, in the Toyota Center training room in Houston. Rockets players and staff bought Yao Ming his former form of transportation for a Lunar New Year gift. Yao Ming went on to joke that he would put his car up for auction on eBay.
This frame, built with custom True Temper OX Platinum tubing, not only has 29" wheels but is actually a 29" mountain bike - possibly the largest ever built! Thanks also go to Vicious Cycles of New York for building a similarly ambitious front fork.
