Sure, Specialized may have turned a few heads with their overpowered-for-the-US e-bike a couple months ago, but this prototype by Audi puts it to shame.

Following the car manufacturer’s purchase of Ducati, they’ve released this carbon fiber monster built with carbon-thermoplastic wheels that weigh in at a claimed 600g each. The effect of the lightweight wheels is enhanced with an inverted single crown fork (less unsprung mass), and the whole thing is driven by 2.3 kilowatt-max (3.1hp) motor with 250Nm (184 ft-lbs)of torque. As Stuff points out, that’s more torque than a Mazda 6 or VW Jetta.

Max speed is claimed at 80km/h (~50mph), but delivery is metered out only up to 50km/h in full electric, the rest of that speed needs to come from you. Consider this the human-assist electric bike if you wanna go really fast. Otherwise, there’s a pedelec (pedal electric assist) mode that simply bolsters your efforts, a pedal only mode with no assist and -wait for it- a Wheelie Mode that balances power while the front wheel is airborne.

From the gee-whiz features list, this bike appears to be more about tricks and street performance than commuting. There’s integration with your smart phone, a remote immobilizer and the ability to track the number of successful tricks you pull off and rank them with your Facebook friends. Video above is motorcycle trials pro Julien Dupont putting it through its paces.

Audi Ducati concept e-bike electric bicycle with lightweight carbon fiber frame and wheels

Range is claimed between 30 and 45 miles per charge, and it’ll fully recharge in about 2.5 hours. Word is it has a hydraulically shifted 9-speed rear cog and full hydraulic disc brakes.


  1. I am going to guess 25k if it ever hits production, looks awesome but don’t think I can ever fit that in my budget .

    I have been planning a e-bike conversion myself for my 2003 Yeti ASX. 8in. of of pure freeride travel and about 36lb. not bad for an old freeride bike that keeps on going and going. It can take any downhill trail and gap jump like nobody business and I can pedal up with it too. But a motor would be nice to get up those hills.

    Been getting the shocks rebuilt and doing some basic maintenance in preparation for my new electric motor add-on. I will be ordering an Ego-Kit ( ) for it. Bolt on HD downhill ready Electric motor etc. Here are the specs:

    70km / h (43.5 MPH )
    40km ( 25 mile range )
    1.5 hours charging time
    1500 load cycles
    80% slope (approximately 38 ° slope angle) under ideal conditions
    Rated power 1200W, 2400W maximum power
    Engine Weight 3.1 kg, 4.4 kg complete (9.7 lb)
    Mid-engine design provides good handling with low center of gravity
    good response to the same suspension as opposed to hub motors

    This thing is awesome and bulit to take a beating. My Yeti ASX plus the kit is under 46lbs The Audi e-bike above weights in at 46.29lbs. My Yeti is a full fledged freeride / downhill bike, no carbon fiber anywhere.

    Cost of the Ego-Kit about $3000 USD plus a decent mountain bike 3-5k
    Cost of the Audi bike unknown. But its got to be way up there! 20k+ for sure

    Watch these video on youtube:

  2. Looking at the link spezilight gave shows wheel weight @ ~1200g.

    In terms of handling the torque worth considering that the drive shaft on the new AMG is carbon and weighs only 2.5kg! If you can put 600+bhp through that and spin out 20″ fat rubber then the torque produced by a small electric motor should not be a problem with a well designed system.

  3. @SteveM: did you read the article? 600 grams each. 1,200 grams for the set. With the full carbon construction, that doesn’t seem unreasonable to have a wheel set that light but very strong…

  4. @KJR
    whats the lighest bicycle rear wheel? 1000 grams for a fraction a horsepower? so how is a 600 gram wheel going to hold up with 184ft/lbs of torque?

    So unless the thing is two wheel drive the back wheel is taking the drive torque all by its lonesome.
