BMW's electric SS

https://www.topspeed.com/motorcycles...-ar180313.html






by Sagar, on The HP4 is an exemplary showcase of cutting-edge technology, exotic materials, skilled craftsmanship, design, and creativity. This tells us all about the experience, skillset and state-of-the-art know-how the folks at BMW have that make them rise above and beyond. But what if the same guys one day decide to power their machine with batteries and motors instead of pistons and shafts?
Donít bother, because they have already done that a couple of years ago. The experimental vehicle eRR, created as a project with the Technical University of Munich, envisioned a BMW badge on an electric supersport motorcycle back in 2015 when the whole idea of electric powertrains was still in the concept stages.

Re: BMW's electric SS

All of this is coming. Sure electric bikes are here but in the next decade the technology is going to evolve 10 fold. I might just last long enough to actually own one.

I really like quiet - electric quiet I'm not so sure - but one can never tell.

Re: BMW's electric SS

You like quiet? C'mon man.... You're right about the technology evolving and the costs are coming down for battery storage. We're looking at repowering a couple of our ferries with diesel electric with an energy storage system that can replace a generator.

Wow - be nice.

When riding I like the internal peace I achieve and don't want any distractions. Well I like some distraction - really love the sound of a high performance 4 cylinder motorcycle's induction system - especially when I'm leaning right on top of it at say 12K rpm's with the throttle pinned wide open.

I hear the music but the folks around me don't.

Re: BMW's electric SS

I rode the Harley Livewire demo bike. That thing was loud as hell. It was a high pitched noise of the motor and drive that I felt would require some good hearing protection even at speed were wind noise isn't much of a factor.

Re: BMW's electric SS

Battery range is the factor keeping my interest in the background for the time being. Both for cars and bikes. Charging time is naturally a factor as well. Changes on both fronts to come no doubt!

Re: BMW's electric SS

Interesting...

I, too, would enjoy a reduction in noise on a motorcycle. The noise tends to interfere/hinder my concentration and enjoyment.

Hearing (lol) that an electric motor makes an annoying whining is kinda disappointing to me.

Re: BMW's electric SS

I've never ridden one last summer at the track an Energica Ego was being tested by Ken Condon from Riding in the Zone. He said the bike did make a whine but nothing distracting.

Surprised to read the HD was really loud - I was under the assumption these electric bikes would be rather quiet.

Siemens has a super quick charge system set up for an all electric ferry in Norway. They're not at the dock very long and they get a significant charge in something like 8 minutes.

Right?

It was a prototype and the noise could have been mostly in the transfer case (hard to call it a transmission when there is only one "gear") to the final drive. Performance was good and bad. The good was that it was spunky enough to pooch up a loftie if you snapped the throttle open while on a slow roll. The bad was to get that kind of power out of the motor, it had a 40 mile range. That would get me about 1/3 of the way through my local afternoon fun ride.

Regarding the Harley Livewire, we all know that "loud motors save lives."
