I'm currently interning for these guys.

Haven't gone public with anything yet though.

e: Also I think the sound of an electric bike could be just as enticing as a motor powered one. Though nothing can replace a proper backfire, but maybe future bikes will shoot lightning as in Akira.

Bumping this thread.

Had a hell of an experience at my internship today test riding the project electric motorcycle to find its range. Tooling around NYC to determine the range of a prototype machine was inexplicably awesome. The sound, the feel, the stares it got, everything felt amazing. I can't disclose much else but safe to say the experience was just as thrilling as my SV650S. Will hopefully be logging more miles on the machine as we move closer to production.

Nah, definitely can't post pictures. It's amazing how competitive the market is, and the number of players in it. The technology is out there in little pieces. Everyone's just racing to put them together in the right way to make a viable electric motorcycle.

You'd be amazed at how inconspicuous an electric motorcycle is. Hardly anyone pays attention, few glance but those that do always do a double take. Especially taking off from a light with a quiet woosh. Little kids in particular get a kick out of it. I passed by a Harley bar with chrome and 'Merican flags littering the front. The whole leather clad group was shocked and stared like crazy as I sat waiting for the light to change. Brought a big grin. The highlight was pulling up next to a man on a scooter and he just stared in disbelief, then woosh, I was gone.

Electric bikes are coming. If this generation doesn't want them, the next will; the ones who've grown up with electronics and rapidly changing technology. They'll put up with the faults and pitfalls of the tech until it surpasses ICE's. The group I work with is incredibly passionate about the project. We're foremost riders though, from many backgrounds, but we're adament that what the project is is a true motorcycle, not an appliance. Even as involved as I was, until actually riding the thing I didn't really see the appeal. Maybe it's just a novelty of the moment, but as far as I can tell the electric powertrain hits just as many of the sweetspots as the ICE powertrain, if not more.

A removable battery pack would be very handy indeed. But I suppose they are quite heavy, any guesses on the weight? 100 lbs in two units would be practical enough.

Weights one issue. Mechanical linkage, securing the connection, and user interaction are also big issues. It's definitely not as easy to implement as it seems.

Also making sure no ones kid or pet turns themselves into a smoking pool of goop when it inevitably gets hosed with is kind of difficult.

Flammable liquid is also pretty dangerous and hard to handle...

You don't have to pull the fuel tank out of your car and refill it for a few hours in your house though, nor does it kill you if you touch it the wrong way.

The bike is being shown in person at Long Beach if you make it there.


drat, I was just down there all last week interviewing at Art Centers design department regarding doing an electric motorcycle focus in their grad program. I've always meant to apply at Mission but it seems like engineers get to have all the fun. At least, that's how my internship at the electric bike company in Brooklyn was.

Congratulations on the SV. Riding from San Francisco to Los Angeles isn't painful until you get caught in the rain for the final 200 mile stretch. And for the love of god remember to charge your MP3 player.



P.S. European lower fairings also make it easier to nestle your feet against the engine for warmth.

I think the Uno would be much more appealing if they didn't try to skin it like a normal motorcycle. It's anything but and deserves it's own style of bodywork that compliments its small shape. As great as the technology is underneath, why oh why do they have to dress is like a deformed midget?

Just guessing from personal experience, but the throttle response lag has gotta be intentional.

At the electric bike startup I interned for we initially tested the bike with direct power and the thing bucked off even our most experienced test riders. Any accidental twist, especially without a clutch lever or engine sound, and the thing would lurch with every ounce of torque all at once. Scary as hell and always caught people off guard. Thankfully our electrical engineers sorted it out quick.

Nah, it basically sounds terrible. Not that the sound inherent to the technology is Mission Motors fault, it's an issue that all high-performance electric vehicles will have to resolve.

Love the way the number decal is painted on both the fairing and the frame. Anyone have any idea what kind of motor Honda is using? It's probably proprietary, which would make them and Moto Czysz the only ones not using an off the shelf power plant.

The company I work for is partnering with these guys to put wifi units on all of our bikes. For safety you can't access any of the social networking features while moving, but it'll notify you if anything comes in.

In case anybody missed it:

Asphalt and Rubber posted:

Launching last night in downtown Los Angeles, the 2012 Brammo Empulse R & 2013 Brammo Empulse broke their cover and officially debuted. Right off the bat from the designations, you can see that Brammo intends for the Empulse R to be a 2012 model, with the base model Emuplse coming out next year (more on that further down). As we expected, the Brammo Empulse R got quite the price bump after its 22-month marination, and will be $18,995 MSRP. Meanwhile when the Brammo Empulse becomes available next year, it will have a slightly more palatable $16,995 price tag.

Featuring a six-speed gearbox the Brammo Empulse R comes with a 54hp motor, 10.2 kWh battery pack (9.31 kWh nominal), and a bevy of brand-name components like Marchesini wheels, Brembo brakes, Marzocchi forks, a Sachs rear shock, and a few carbon pieces
(read the full technical specifications here). Getting a revised look, the basic Empulse design is still there with some subtle changes (some for the better, some of the worse, in our humble opinion). Touting 56 highway miles and 120 city miles, the Empulse is going to suffer from the same range-limiting use that other electric bikes on the market are facing, though Brammo has thought to include J1772 Level 2 capability on the bike, which should make for some more rapid charges away from the mothership. We like that.

There is no doubt that Brammo has raised the bar for electric motorcycles, as the 2012 Brammo Empulse R seems to best the Zero S ZF9 in virtually every category (build quality, horsepower, range, etc) — except price. Expected to be out in limited numbers in June 2012, and in volume in Q3 2012, we imagine the $18,995 MSRP cost will carry with it a bit of sticker shock (hey-oh!) for many buyers, especially after the Brammo Empulse debuted with a bargain basement $14,000 price tag roughly two years ago.

The hope from Brammo is clearly that the six-speed transmission, premium components, and comparable segment machines will make the added cost justifiable to consumers, though the reality is at the end of the day, you are paying premium motorcycle prices for a machine that most sport bike enthusiasts are going to experience a very limited range with. With Brammo one of the original manufacturers touting the lack of a need for a gearbox on an electric motorcycle (they make nearly maximum torque at 1 rpm, you know), CEO Craig Bramscher admitted the company’s previous statements at the launch, but retorted that the IET gearbox from SMRE provided an entirely different riding experience from before.

We will have to experience it for ourselves to believe the hype, though before we get too cynical, we do have to admit that many fossil-fuel riders will find their opinions about electrics changed once they experience the surreal “flying” effect that riding a fairly silent electric motorcycle at speed provides. Expect a ride review in the next couple months, with a strong focus on this gearbox technology.

With photos of the Empulse R leaking ahead of the launch, and Brammo already teasing us with the technical specifications, the real surprising news at the LA launch was the added year-long wait for the Brammo Empulse base model. Kitted with some more basic components, the differentiation between the two machines is surprisingly subtle, and we suspect there is good reason for that. With motorcycle riders used to two years or longer between model revisions, the ever-changing electric vehicle industry is experiencing substantial improvements and changes on an almost quarterly basis.

We know that Zero Motorcycles is already working on an “Empulse Killer” for the 2013 model year, which will benefit from cheaper, denser, and more powerful battery technology. Surely realizing that the standard product life periods are not applying to electric motorcycles, it would not surprise us to see the Brammo Empulse R updated for 2013 as well (think 12 kWh, and more hp), with its production line at the current specifications continuing under the 2013 Brammo Empulse banner.
Such a strategy would allow Brammo to keep pace with its competitors, as well as the changing technology in its industry sector, while at the same time allowing the Oregonian company to benefit from assembly line processes and economies of scale in component sourcing. Of course that is just speculation, but it’s what we would do in their situation. As always, time will tell.






I think it looks a bit pregnant. Still, the early adopters should be happy.

It's disappointing they didn't offer a version with the RR bodywork. You could at least look good on your painfully short ride.




Mission Motors still wins the good-looks contest of the EV bike world. God what I would give to work under the man who designed the Mission R.

The last company I interned at had the very issue of choosing between regenerative braking and a freewheel. In the end we decided to go with the freewheel, because you saved more energy coasting to a stop than forcing it to come sooner. Not sure if that still holds true with todays tech since this was three years ago.
