2014 Empulse R

After introducing the 2014 Model Year of Empulse and Empulse R, Brammo now shows us a tech overview of the bike.

Brian Wismann describes the main components on the cutaway demonstrator – from battery cell to the drivetrain.

The 252-cell battery pack has 9.3 kWh and can be charged via 3.3 kW charger. The three-phase 40 kW motor is coupled with a six-speed gearbox.

“Curious about all of the inner workings of a high performance Electric Motorcycle? Ever wonder how many battery cells it takes to power the ultimate street-fighter? Now you can watch Brammo’s Brian Wismann dissect the high-tech inner workings of the award winning Brammo Empulse! From Battery cells to electronic controllers to a powerful electric motor, Brian breaks down these components and more, up close and personal. Check out this unique technical overview using a “cut-away” of our 2013 Empulse as seen at CES!”

Very trick.

I followed this thing from the git go and actually had an order in (but got a Volt instead). They were very late getting it to market because they decided to get rid of the single speed tranny.

So they went w/ the 6 speed and raised the price considerably.

I really like the level 2 charging capability. It makes the bike way more usable.

I don’t understand that 6 speed gear box anyway. One would do, two for better top speeds and better efficiency at high speed but six? I test drove the Inertia and liked how no gear shifts were needed.

Just wait for these electric bikes to get into a horsepower war.

I hope Brammo gets its battery cost under control someday so these bikes become more affordable because they are a blast to drive. Once Tesla’s gigafactory comes on line battery cost should be well below $200/KWh but I’m not sure if Tesla’s batteries have powerdensity that’s suitable for the sort of small packs that go into these bikes.

This bike in particular only has a 40kW motor driven by a 9.3kWh pack, as noted in the article. That’s only 20% higher of a C-rate than the Model S driving a 310kW motor with a 85kWh pack.

But for higher power models, I see your point. Bikes have less room per unit of drag than a car, so it’s a little harder for them to compete.

What helps is that electric motors have great torque which acts as a substitute for raw KWs so one can have great performance without putting unduly heavy strain on the batteries.
