BRD electric motorcycle

I know people are going to shit all over this thing but they're starting to make this things lighter, faster, and longer run times. I like the fact that you can run both gas and electric. Says 100 miles between stopping which is pretty decent. Top speed isn't great and price is still high, but I'd love on off the street dirt bikes to commute to work through the city. Check the video. They've come a long way in 4 yeara and in acouple more years and it will only get better.

Well, Hybrid might be a better term.....It still has an engine.

From Here: http://www.popsci.com/article/cars/silent-hybrid-motorcycle-us-military
When not running on electric power, the bikes would use gasoline, JP 8 (a military jet fuel), diesel, and other fuels that could recharge the batteries as they propel the bike. The bike could also be used to charge electronic devices carried by the troops.

Pulliam says DARPA wants "military users to be able to scavenge fuel while on missions," so compatibility with a range of fuels is important. The bikes are also two-wheel drive, which gives them even greater ability to maneuver difficult terrain, such as narrow mountain paths and over fallen trees.

The hybrid off-road motorcycle has a strange parentage. The body comes from BRD's RedShift MX, an off-road all-electric motorcycle. The engine is based on a hybrid electric/fuel drone engine that Logos Technologies is currently developing. The point of the hybrid motorcycle is not fuel efficiency, though there could be some gains there. Instead, the military motorcycle would run electric-only for up to an hour straight, which is one hour of nearly silent use. This is less than the two hours of running time that the civilian RedShift MX gets per charge, but the DARPA-funded bike project isn't a direct modification of the RedShift; it's a new hybrid bike that borrows some features.

Like All electric bikes, this one has a 50 mile range on electric, and 50 on fuel.

An all electric MX bike is fun for the first hour, then you have a dead battery. You can easily carry a 5 gallon can of fuel for a gas MX bike, but a spare battery is around $7k and only gives an additional hour.

So the technology of an electric MX bikes works, but it isn;t practical for a day of fun....Not do electrics bikes have practical ranges. I can go pretty far on 2 gallons of gas on my CB360, fill it up in 2 minutes, and go pretty far again....Until electrics have a realistic range and recharge time, they aren't going to be really usuable except to people who only ride short distances.
 
Looks like one of the big Japanese manufactures has decided to get in the game now too. Yamaha has a street and a dirt bike built but no idea when and where they will be sold. Street bike is less than 220 lbs, I'd say it would be a blast to ride.

The range on these things are getting better. I commute into the city everyday and it's only a like a 32 mile round trip, so it would be pretty sweet for that. Can't justify the price but expect them to come down. I do like the rumble of my arrow two in to 1 pipe on my Scrambler so I'd miss that as well. The dirt bike version has me interested thou. The stealth of it might allow you to go places you normally wouldn't be allowed. The lack of maintenance is nice too.

Well, when you say lack of maintenance, are you including the 500 hour battery replacement at $7000....

The fifty mile range is 50 miles at low speeds. If you are going 35 miles at highway speeds, your chances of getting home are reduced quite a bit....If your company lets you plug in at work, then maybe feasible....

if you want to ride on a track all day, well 2 hours is all you get.... Unless you have a spare $7K battery on hand. The CRF205, well, just fill from the 5 gallon can of gas, and you are on your way.

the math doesn't work for me..... First cost too high, and the battery cost as much as a new honda....Does a CRF250 require a motor rebuild every 60 hours? Do people only keep their bikes 200 hours of riding? some odd numbers by BRD, if you ask me...If you go 501 hours, the BRD doesn't look so hot with the battery cost.

Where the hell does a 2200 dollar service come from at 60 hrs? That's just ridiculous.

I'd love an electric bike. Full torque the instant you hit the throttle would be a blast.
 
I'm all for electric motorcycles. There's a lot of potential in the technology, and they have been improving in leaps and bounds already. I know there's at least one owner on ADVRider that is doing a long term review (which I haven't kept up with.....).

Just read recently that one of Zero's bikes has a battery life of something like 385,000 miles. After that 3 rolls over on an odometer, I'd be more than happy to shell out the $ for a new battery.

That mileage on a battery wouldn't be too bad at all, but if its 500 hours that would be nuts.
 
the whole weakness of the technology lies in the battery life+charging system.
everything else is highly developed (e.g.motor).

i think there will be huge jump of practicability of the battery problem gets solved.
 
Maybe somebody here knows - I recall reading / hearing about the future of battery powered vehicles. They said one solution was to have battery stations instead of gas stations. Ride for an hour or two until your battery is low, pull in and swap out a fresh battery, and you're on your way. I think it was on TedTalks?

i´m from austria and here we already have this kind of model.only on a few stations,not nation wide.

there are a few different models how to deal with that problem.i hear dit on a radio show.

swapping out old batts bringin in new.this model really depends on the way the batts are built in the vehicle,could be dangerous,such a huge batt pack can turn into a bomb when used incorrectly.

there is another model (a german university is doing scientific research on that one):using the bat fluid like fuel-->batts get recharged by sucking out the old fluid and pouring in the freshly charged.

Tesla's Supercharger stations will soon have the capability to swap batteries. Allegedly the swap is completed in 90 seconds. I'm taking it with a grain of salt, though.

I would LOVE an electric bike. But I agree with Myd, the battery technology just isn't there yet, at least for me to make it financially feasible.

I am confident that science will find a solution soon and by the time I am old and gray, I will be tooling around on an electric bike.

Shit, I'm already old and gray. Hurry up science!
 
The BRD is a $7000 Battery. You really want to stop somewhere, exchange your new, but needing a charge, battery, for some used battery with who knows what kind of life left in it?

Not a model I am fond of.

There is other chemistry, like Zinc Air, that allow you to add fresh zinc plates and have a full charge immediately. But do you think the price of zinc is competitive to gasoline?

I am not against the technology, but it seems the Chevy Volt is the only viable type of electric car (hybrid) that is even close to viable....But ultimstely, it is still a fossil fuel engined car....and really expensive too...

The technology is still not ready to replace the ICE

No the technology isn't there yet.
But it will be soon. And without early adopters it will never get there.

I was thinking about the speed of technological advance yesterday on my way back from the meltdown.
In a single persons lifetime we have gone from zero electronic technology to walking around with the sum of all human knowledge instantly accessible at our fingertips in a tiny screen connected to billions of other tiny screens spanning the globe.
I'm pretty sure the electric motorcycle will be the norm pretty soon.

10 years ago I had one of the first commercial "palm pilot" pda's. Black and white and the most exciting thing it did was set an alarm for your meeting at 9am. And here I am 10 years later typing out a response to some guy a thousand miles away, wirelessly, from my tiny screen that has more computing power than the whole of creation did 20 years ago.
 
Electric cars started in the late 1800's, early 1900's but became surplanted by the ICE.

The difference in battery tech and electronics, is that the batteries didn't become a whole lot better (better, but not leaos and bounds), but the electronics themselves became leaps and bounds better, using less current to do the same function.

The problem is a mid sized sedan, even an aerodynamic one, still needs quite a bit of energy to propel itself at highway speeds. Power density from stable batteries has not improved much, and a HP is 776 watts whether from an engine or a battery.

The range of Electric vehicles in general, remains close to that of 1912.

Buffalo Electric Co. 400 Military Road, Buffalo NY.

1912-1915 Buffalo Electric Vehicle Co.

Founded by Francis A. Babcock, he then formed the Babcock Electric Carriage Co. in 1906. In 1912 his old and new companies merged, along with the Buffalo Automobile Station Co, and the Clark Motor Co. They had Diehl motors, Bevel drive, Philadelphia batteries, and a 100" WB.

1903 A 2 pass Stanhope @ $1,650. Said to go 17 MPH for 50 miles.
1913 A 2 seat roadster and a 4-seat coupe both at $2,600.

We can go alittle faster for 50 miles, but for a variety of reasons, unless you go very exotic in technol0gy both in the electrics and the chassis, 50 miles is still the average range.

The cost is also very high...Which can come down, but a Toyota Corolla basic model is 14K new out the door. Compare that the BRD motorcycle at about the same price.

A corolla has a lot further range, carries more people, cargo. 500 hours at 55 mph is 27500 miles. At $4.00/gal, at 30 mpg, that is $3,700, about half the price of the BRD battery. Sure there is oil changes and maintenance, but the BRD is a single rider machine. And requiring recharging every hour of use is a huge draw back...

Power density in the battery has to increase a huge amount to be viable for the US style of driving, and the recharge infrastructure is not there. Not the recharge station, but the capacity to use a high amp, hi volt recharge, as well as the elecdtric companies ability to provide it. Calif. has brownouts now. Add the extra load, and even if you could charge it quickly, you can't if the grid can't supply you.

Every one of these drawbacks has a good possibility of being addressed, but I don't see it in my lifetime. Just fixing the electric grid capacity is going to be a long time in developing.

Maybe I am pessimistic, but I work in a company that makes cogen products (Gas turbine, fuel cell, steam turbine) that use the waste heat to cool and heat abd being a little intimate with power in the northeast, I don't see it really working.

Places like Manhattan, which is a place the limited range would be ok, has limited power, not only from generating capacity, but infrastructure wiring. Even if capacity doubled in the plants, the underground wiring is old and not up to increased capacity.
I imagine most cities like Boston, Chicago, etc, are up against the same barriers.

I like electric vehicles from a technology, engineering standpoint, and if I had Jay Leno's money and garage, I
would own a few. Since I don't have that, I need the practical, fill it up in 5 minutes and go 3-400 miles on tank convenience. Electric isn't even close to that.
 
Agreed on all points for the current market.
My point was that we cannot anticipate how rapidly things can change ;D

If you aren't in a particular field, I agree....but if you are reading trade magazines and in the business, research articles and trends appear....So if you asked me about the next gen processor specs, I would have to be looking for that.

But I am in the power generation business, receive trade magazines and articals, so you get an idea where things are going.

For instance, Windmills and solar power are not the next great thing at this point. The cost of maintenance, the volume of land they need to work, has not only slowed the rate of growth, but in places of limited land, have actually reversed the growth trend. The problem, as in electric cars, is not that they don;t generate power, but do not generate on demand. So storage is needed, and that has become problematic. Like the electric car, large volumes of watt hours are difficult to store. Unlike a steam powered electric plant, you can't increase the output of solar or wind when you actually need it...Again, places like NYC have no land space to place wind mills, solar panels, and the storage of energy needed.

If and when high density energy storage at reasonable cost become available, it would not really be for cars, but for storing alternate source energy so it can be available on demand.

While you can't know when the next big thing may come, if it does, it will surprise a lot of people, as many are working on it with poor results.

What you really can't predict is disruptive technology. I suspect another technology will come around that will make electric cars seem like the 1890's invention they are. Tata Motors are building compressed air motors on vehicles. No pollution, air can be easily piped or compressed away or at home.... Stronger air tanks allow higher pressures and longer ranges . Maybe some other similar tech may prove electric to be a dead end...
 
Like you said it's actually a hybrid so you can go a distance of about 100 mile on charge and gas. That's not to bad. Only getting about 110 from my Scrambler. It's not a long distance touring bike. Battery life and charging times will only get better. Prices will drop as well.

Pretty cool article how the marines are using these in Afghanistan.
