:2thumbsup:2thumbsup:2thumbsup
sounds like the rider skill level may have been a bit mismatched, and track was suited for electrics, but still, an awesome result.

some specs on the zero-mx
weight 71kg
power 23hp
torque 68Nm
range up to 2hrs40

[motocoorg]

interesting!

[fridayflash]

ok i voted before id read the articles...nawty nawty...now id say
when theyre sorted id be keen, be a bit of a shame not having the
sounds and feel of internal combustion engine power tho

[cheese]

I told you guys. Its not far away from being a realistic race machine. Zero have come a long way in a short time.

[EJK]

That's almost a Ducati 900 Monster equivalent amount of torque from a 71kg machine!

[FlangMasterJ]

They should include a built in amp which plays any bikes engine sound of your choice.

[secondfield]

haha, yeah, the adb test was favorable but dirt action magazine said they had a loong way to go especially with the suspension. Personally, i think they are for faggots.:banana:

[Ride it till the red]

I can't imagine suspension would be too much of a worry, thr technologys already there from current bikes just need a little tweaking. It would be battery life that I would be querying, and how long before this life starts to deteriorate?

Any bikes a good bike aint it Secondfield? Or are you just sour coz you can't ride over there? :crazy:

[flyingcr250]

can i plug my i-pod in to it??

[gazmascelle]

I don't care if my bike runs on petrol, electricity, or horse shit. As long as it goes when i want it to

[oldskool]

Electric Dirt Bikes will rule the earth

[cheese]

Electric Dirt Bikes will rule the earth

And the 4 stroke will die again.

Battery life I'd say would be about 1-2 years.

its a mountain bike you dont have to pedel.

[bogan]

4 strokes are gonna be killed by that new type of two stroke soon anyway arent they? Im hoping so cos two strokes are fucking epic, I think i shall program a two stoke powerband into an electric bike. Then these new two strokes will be killed by electrics, which will then be killed by something more awesome

[kezzafish]

going by that video it looks like it still lacks massively in the power stakes. And when they make it powerful enough the batteries their using now will last about 15 mins. But no doubt they'll get there

[tate35]

Interesting...I would give one a go :crazy:

[clmintie]

Western Springs could become a permanent MX/SX/endurocross facility.. :Punk::Punk:

[t595]

saw one riding round phillip island track last weekend... everybody was keen to see it go,until it went past .was the gayest thing ive ever seen,sounded like a sewing machine!! 90% off the crowd where we were couldnt stop laughing,i think the other 10% were alseep. But no thanks not for me!!!!

Might be nice for the ponsonby latt'e crowd tho???

[Crasherfromwayback]

that all we can have is an electric motorcycle...is the day I give them away.

Part of the love affair I have with bikes is the total feral response an internal combustion engine has when I wring it's neck. The sound...the smell...and knowing how it works. Stick to doing the vacuuming if you want to go electric.

people used to say the same thing about going from two stroke to four stroke <_<

[Crasherfromwayback]

people used to say the same thing about going from two stroke to four stroke <_<

Maybe so...but at least they both burn fuel

[McJim]

I never realised how many clunks the sound of the engine covered up.

If the world of bikes goes electric I certainly will miss the sound of my Ducati.

[GSVR]

Only real issues I see for electric bikes is the ACC levy going up once someone has fallen off one... and then the power companys complaining the "roadies" are using all the power and its cost will have to quadruple or they will turn it off mid winter.


Not enough options on your poll Bogan!

Heres KTMs electric :confused:

sweet, bout time one of the big manufacturers put something electric together, not surprising that it KTM.

[mattbishop]

Here's my electric:
http://bvt.co.nz/devlopmentlab_files/e-bike9.JPG

Had it out for the first time this weekend, got it up to 110 km/hr downwind. Acceleration was poor, maybe similar to a postie bike, but a good start. Can only go quicker and faster from here.

One of the great things about electric bikes is that they are accessible to DIY mechanics. I built an electric bike (well, converted) in about 10 weekends with off the shelf components. Try building an ICE system in that time... It gets to me that things like fuel injection and CDI's have taken away the ability for the average man to build or maintain a (competative) bike and have left us bound to the big manufacturers. Electric is a way to get that back.

[cheese]

Matt, if you want to dick about with EFI, have a look at micro squirt. that will do everything that you want to with EFI on a bike.

I had a read of your site. Cool stuff! I would love to do the same thing to a dirt bike. What motor are you using BLDC? Zero are using a 17kw one. Where did you get all the parts from?

[mattbishop]

micro squirt ... I'll have a look, sounds like a good thing alright.

I've got a BLDC motor, rated at 3kW continuous. No idea what it'll do max, but I'm aiming for 48 V x 300 A, so 15kW. Got most of the components when I was living in China last year, but they're all available over the net.

I did think about doing a dirt bike, but the space constraints are tighter. Would be good though. If you're gonna do it anytime soon, I'd suggest headway lithium cells (can build your own battery pack to suit space) and an agni motor or two. If you leave it for a month or two, there'll be a whole 'nother set of components you'd want, things are moving really quick with EV components at the mo.

[bogan]

I know of one project a guy did on a dirt-bike, he got two PERM-132s in to it, motors about 18kw each! Dont know where he put all the batterys but it sounds like its a bit of a weapon :eek: tried to get some more info on how it goes, but havent heard anything more.

[cheese]

Interesting info cheers. Be interesting to see the pricing on those batteries.

I spent a good amount of time in China this year also. We have a factory in ShenZhen. That place is a mad house.

Did you build your own motor controller?

I'm currently working on my own one, I wouldnt recomend it unless you want to learn how it all works etc. If you just want something to do the job, buy an already made one.

Got some info from electricmotorcycleforum


There is another option we are offering. If you need your Headway cells faster, we can ship them air freight from China at $95. The same prices on our website are valid.

Headway 38120S 10AH at $17 each
Headway 48v 10AH Battery Pack w/BMS at $349 each
Headway 48v 20AH Battery Pack w/BMS at $699 each

We also have two different Headway charger options available.
1) 48v 2a for $36
2) 48v 6a for $78

Contact travis@evcomponents.com to order.

Price breaks for loose cells are as follows:

1-100 cells = $17
101-200 cells = $16.75
201-500 cells = $16.50
500-1,000 cells = $16.25
1,000+ cells = $16.00

prices are usd and i doubt the shipping cost would apply to here, but gives an indication.

got a link for that dirtbike project, http://evdrive.com/Emoto_project/moto_project.html looks like its only 25hp, must have loads of torques though! cant figure out what motors its got.

[mattbishop]

I reckon they are perm 132 motors in the evdrive bike. At least, the shots of the back of the motors look right.

Looks like we're going to have to do at least a modification of the controller we have. It's a Kelly controller and is supposed to be 300 A, but we're not getting all of that at low speed. Apparently, that's well known for Kelly controllers and if you want a 300A controller, best to order a 400 or 500 A. On the positive, it is easy to configure and has a desktop interface and a fair few battery voltage/temperature protections built in. So, we will keep all of that and just upgrade the MOSFETs and capacitors (and maybe go to water cooling) and see if we can get more amps.

Interesting information on the headway battery prices, Bogan. Looks like about $2k NZ for a decent sized m/c battery pack.

[theblacksmith]

can i plug my i-pod in to it??
I think you'd have to -and a couple of speakers so we know you are coming.

[SPman]

They'd be great for around town.
Saw heaps of electric scooters and electric pushbikes in Beijing.
Otherwise.....where's the noise, the drama,........I think I'll stick to an explosion motor for now.........

[roy.nz]

I need the fumes !!

[bogan]

I need the fumes !!

it says you ride a a crf450, if you were really in it for the fumes you'd be on a two stroke:whistle:

[secondfield]

To get that authentic motor noise maybe you could just put cardboard held by clothespegs in the spokes of the wheel ....:whistle:

[kezzafish]

i don't think they could spare the drag on their power output at the moment

Or behind a 2 stroke maybe??:eek:

[bogan]

well if you are on a four stroke that goes without saying anyway dunnit :bleh:

[oldguy]

Will they last a 30min plus 2 lap moto, at full race pace.

All good and well its fast off the line, and into the first turn, still just a toy, couldn't see them doing a GNCC

[DELLORTO]

they wont take off........who wants a bike that makes a chain rattle noice.??...if no-one buys them they'll never take off. The only thing their good for is noise restrictions.......i could have a mx track in my garden and ride it at midnight...:Punk:

not sure on that, would be pretty close if not there though. There was a 24hr race, batteries were swapped out when depleted so im assuming they would last a decent amount, swapping batteries every 10 mins would kinda defeat the purpose of a 24hr race. Also worth noting, only one bike shat itself during the 24hrs (motor issues), one other didnt finish cos someone forgot to tighten the suspension bolt :doh:.

might i direct you to the poll, seems the majority would have one once thier performance is a good as petrol bikes.

LOL the haters....

You wait, electric technology is going to leap forwards massive amount in the next few years. Demand is there and I think that you will see the die hard petrol heads and then you will see a migration to electric.

With long races like a GNCC etc, you would probably have a battery swap out. The likes of the zero will run for 2 hours I think. My thoughts on a good set up would be a group of batteries under the seat. So say your bike runs on 56v, you have 4 56v batteries, so if you are doing a short race, you use only 3 batteries, long race use 4.

[tommorth]

could get rid of the chain noise by useing an enclosed belt drive

the thing I don't get is why do they all have to be so ugly

[oldskool]

If I had the luxury of room for an xtra battery I'd take xtra Volts and squeeze more outa my motor.

[klx kid]

i agree with everyone that says that electric bikes are GAY! as people have been saying, they need to look like desent bikes instead of how ugly they look now and they need the noise ect that real moto-cross bikes have. the only advantages i can see in those electric things is that they are light, and save on fuel money......(but you will have to buy batteries anyway). i just cant picture moto-cross races with the sounds of rattling chains and no other noises! :no:

[Kickaha]

How do you decide which capacity class an electric bike will race in if you wanted to run it against petrol powered bikes?

[Reckless]

Probably the way they do it in most motor racing using high amounts of technology and Calculations LOL!!! NOT!
Same old rule Kickaha,
If it wins to much restrict it or weigh it down, if it doesn't leave it alone!

[oldguy]

They are not that Eco friendly, what the F**K do you do with the spent battery's? land fill.

Oh yeh, charging the battery's, just another charger plugged into the power socket at home.

Transpower

Lithium batteries are recycled so is lead acid batteries (although lead acid is normally made into ammo....) Nickel metal ones were an issue, but everyone is now going to LiFe Lithium lead

Also the battery charger isn't as draining as you think and it cheaper than petrol.

[secondfield]

Maybe these batterys will get the nod ...

[dammad1]

Cant see me riding one, but there is some really cool kids ones around, I was watching two four year olds riding a couple from OSET and they were going really well, a great way for the kids to learn to ride and dead quiet, I'm going to get my little girl one for xmas.

[NordieBoy]

I'd get one in a heartbeat.
Regenerative braking for the downhills...
Quiet...
