Audi e-bike Wörthersee lets you pop wheelies eco-style, plays nice with your smartphone

We're no stranger to e-bikes here, but most of the examples we've seen so far have very much been meant for A-to-B rides. Audi's aiming to fix that with its e-bike Wörthersee prototype. The carbon fiber transport not only has a strong 2.3kW motor -- the most powerful ever in a bike, so says Audi -- but can use that power for tricks. You can flick the Wörthersee into a wheelie mode and either shift your weight around or leave it fully automatic, depending on the fierceness of your stunt skills. Not that it'll be a timid ride if you prefer to keep both wheels on the ground, as a motor-assisted pedaling mode will take you up to 50MPH, and you can still ride at 31MPH if you're not keen on using your legs. That's faster than the already speedy Grace One City we tried, folks. The vorsprung durch technik also comes through a smartphone tie-in, although in a much more stunt-savvy way than the app- and tuning-focused Ford E-Bike Concept: it tracks video and trick runs, both for its own game system and for bragging rights on Facebook.

With a very light 3.5-pound carbon fiber frame and a quick 2.5-hour charge-up time, the e-bike Wörthersee sounds like a wild ride that will charge quickly enough for a spin on your lunch break, but we wouldn't rush to put down a deposit. Audi is calling the prototype a "show bike," which is a sign than the design as-is won't show up at the local sports store. We'll let you know if the Wörthersee or a more pragmatic descendant makes the leap to a dealer.
