This Lexus bicycle has apparently been quietly making the rounds since the last year's Tokyo Motor Show, but the automaker has rolled it out again to coincide with the Great British Bike Ride, and it's taken the opportunity to dish some details on it. While it's still just a concept, it does exist in prototype form, and packs a 240-Watt electric motor that's powered by a 25.9-volt lithium battery pack, which promises to give you a little extra push when you're tired of pedaling. Being a Lexus, it also follows the "L-finesse" design language, and it relies on the same principles of the Lexus Hybrid Drive system found in the company's hybrid vehicles to recharge the battery through regenerative braking. Unfortunately, Lexus says it doesn't have any plans to put the bike into production -- but that may be for the best, we're pretty sure the future of transportation is one-wheeled anyway.
