Lexus release $10,000 bike.
The hand-built Lexus F Sport Roadbike will soon go on sale in Japan, with a limited run of only 100 bikes being sold through Lexus dealers as “a way of demonstrating the company’s knowledge of carbon fiber construction and advanced electronics”.
The bike weighs 15 lb and uses an electronically controlled derailleur, said to be the bike’s biggest advancement.
Shimano’s Di2 9070 electronic shifting system includes a microcontroller, network device, and battery inside an enclosure about the size of a conventional 9V battery, mounted at the base of the handlebar stem. A thin wire inside the frame enables the unit to “talk” to the derailleur, commanding it to upshift or downshift at the will of the rider. “We rely on the rider to decide when to upshift or downshift,” Williamsen told us. “You could think of it as a contemporary manual transmission, like the one in the LFA (supercar).”
