BMW eRR Electric Super Bike Might Become Reality


Dead Dinosaurs vs. Electrons: BMW may pit its ultra elite 215 horsepower HP4 Race against its own electric S1KRR-based “eRR”

With both Harley-Davidson and Royal Enfield poised to release electric bikes in the near future, it’s become abundantly clear that the electric bike movement is here to stay. With several electric car and scooter models currently on the market, BMW has recently turned its attention to the development of its electric powertrain vehicles. Now, what started as a simple demonstration exercise from three years ago has become something markedly cooler.


Back in 2015, a collaborative project was hatched between BMW Motorrad and the Technical University of Munich to create a high-performance electric two-wheeler worthy of wearing the Roundel. BMW intentionally refers to the eBike as an “experimental vehicle”, removing some of the liability involved with attaching its name to the project. The “eRR” was built around the previously developed chassis from the S1000RR, given an electric powertrain, and then wrapped in carbon fiber S1KRR bodywork.

BMW’s stake in the collaboration was motivated by the desire for info on low-speed performance; an area in which electric motors excel. Because eMotors offer full torque on tap at any given time, electric motors almost always have the upper hand on internal combustion engines below 30 miles per hour. This is the reason why many modern “supercars” are hybrids, not to save gas, but because the electric motor is used at lower speeds, and then the gas engine kicks in at higher speeds allowing for the best of both worlds.

The manufacturer has yet to release any specific specs or info on the eRR. However, rumor is that BMW wants to pit the eRR against its own ultra elite, $90K, 215 horsepower HP4 Race in a sub-30 miles per hour drag race. This alone speaks volumes about the electric super bike’s performance, because not only is the HP4 Race’s engine insanely powerful, but the bike’s frame, wheels, swing-arm, and bodywork are all made from carbon fiber. This all resuls in a wildly impressive claimed power/weight ratio of: 1.472.

Once BMW reveals more information on the situation, we’ll be sure to check back in with you, but personally, I’m really hoping this all BMW battle will be more than a hypothetical thing.

    This is just Business. If you don’t make product that BEATS your current line, someone else will.

    BWM getting smart.

    Below 30 MPH, almost every bike over 500cc can lift the front wheels, which is the limiting factor on motorcycle acceleration. If electric was quicker, it’s probably due to other reasons like lower center of mass that prevented wheelie than power/weight ratio.

    1. Adrian Mullett says:

      Wow man… U have no clue how modern bikes work… Are you familiar with launch control, wheelie control, ABS, real lift mitigation or active suspension? Cause you sound like you rode a dirt bike once in middle school and thaaaaats about it.

      1. mxs says:

        Not speaking about the benefits of ultra smooth power delivery from the EV power-train vs. the always present power pulses from the gas engine.

      2. SparkEV says:

        If you think electronic controls will make it quicker, you obviously have no idea how Physics work. Best acceleration is at the threshold of wheelie, and if a bike is capable of wheelie at 30 MPH, they have more than enough power. Billion more horsepower or any amount of electronic control will not make them accelerate any quicker.

        And your argument of dirt bike clearly illustrate my point. What gets quicker acceleration is center of mass in most cases (bike more than 500cc), not the power. Apparently, you haven ridden anything with power, dirt bike or otherwise.

        1. Djoni says:

          I’ve ridden both and it’s true that the main factor, once you master the slipping clucth, is to keeep the front wheel barely on the ground.
          Except that heavier bike and swing arm length make various wheelie sensitivity.
          In short I use to have a sub 2 secon 0-30 mph Titan Suzuki 500 cc two strokes that was impossible to wheelie unless you pull with all your strengh the handlebar while releasing all the power.
          I had a Can-Am that was a lot easier to wheelie and still much more stable that just about any MX in the field.
          Some guy just hang on one wheel as much they will.

          So in short, E racer bike could pretty much accelerate faster, weight, length, balance and the electric torque delivery can do a lot better for sure.
          I bet it would be no contest.

        2. Will Davis says:

          Electronic assists try to prevent a wheelie by reducing power when the front wheel begins to lift off the ground, which theoretically makes a bike faster in the hands of a less experienced Rider who is more cautious about trying to avoid lifting the front wheel, as all they have to do is pin the throttle.

          The thing limiting motorcycle acceleration is always the weakest link. It could be traction, it could be power to weight. It could be many things. Front wheel lift is just one facet and solutions include a wider wheelbase, shifting weight forward, etc

      I’d love to see a Sofa Glide do a wheelie.

      I’d pay money to see that.

  3. Bolt driver says:

    0-30 is maybe the first 30 or 40 ft of a launch. Sport bikes are 200hp and 400lbs. So maybe 550-600 lbs with rider. That is still 3lbs/hp. That would be like a 2000hp tmS. You probably are not shifting to second until 70-80mph. The limiting factor is flipping over and now with electronic controls and flyby wire the bike does all the work. You just pin the throttle and go.

    they are 2.6 sec 0-60 and high 9’s for quarter mile. So if you compare that to a tmS you can see that the extra traction of the car gives faster low speed acceleration and then the lighter weight and higher hp takes over at higher speeds.

    Silly question; would two-wheel drive allow for more power transmission to the ground? Thus better balance & less chance of wheelies?
