Californian cyclist Denise Mueller flew 147mph to set a new women’s world speed record at the weekend, drafting behind the world’s fastest production SUV on a bizarre-looking custom-built bike.
The bike was built by Chris Garcia of SD Wheel Works, with help from DaVinci Bikes and KHS Bicycles. It’s designed to provide extra stability at high speeds far beyond any regular bicycle, and features two 60t chainrings for double-reduction gearing.
One full revolution of the pedals equals 125 feet. When Mueller is travelling at 140mph, her cadence is 100 rotations per minute.
The bike is a fixed gear, with no coasting or shifting for Mueller, who requires towed up to speed with the enormous gear. It looks like some sort of cross between a Brompton, a downhill bike and a space buggy designed for riding on the moon.
