Battery-powered bicycles seem to be popping up everywhere these days. But none quite like this.

The Audi E-Bike Wörthersee, named after the town in Austria, has a 3.5-pound carbon fiber frame and boasts the same power-to-weight ratio as an A4. That’ll get you to 50 MPH via the motor-assisted pedaling mode, or 31 MPH on the motor alone. And 44 miles on a single charge with a 2.5-hour charge time means you’ll actually be able to drive the thing beyond your neighborhood.

There’s also a “wheelie mode” that uses an electronic control system to help the rider maintain their balance during stunts, while a smartphone hookup and a on-board touchscreen computer take video images recorded via an in-helmet camera, and upload them to the internet.

Still, as bad as you may want one, you can’t have it. The prototype is currently just a “show bike.”
