Mission One electric sportsbike

As long as it handles like my fossil drinker and produces the same feedback in terms of handling and sound I am happy!

Not 100% on the sound but the handling in theory shouldn't be too hard to get similar given the normal weight and distribution of engine/fuel etc...

Yeah I just had seen the vid.. actually does not look that painful.. hehe. Now, if they can get the bike running on earths free energy. That would be something special!

Meh, I'd be happy enough with it running off nuke plants but not so much at the moment, instead lets stick tonnes of wind turbines everywhere and let people deal with the horrible power-grid implications later...

No no no my son, "Earth Energy" is something the environmental hippies forget about when they started protesting against ugly poo wind farms.

Would ya wanna ride at night????? bugger that, i wouldnt even idicate. Opps never did lol.
But a great solar panel sitting on the garage roof charging it up over the week for a small saturday or sunday run would be a go for me.
Id be keen.

Interesting stuff, thanks for posting the numbers. Is the 5.3kW for 100km/hr a standard rule-of-thumb type value or has this been calculated for your specific application?

What are the motor and controller that you are using and roughly what are they worth? Is there a thread floating around with any of this info?

I'm doing my masters in electrical engineering on EV related stuff at the moment, but I've never really run the numbers on an electric bike before, makes a lot of sense and is a much easier target than a full EV.

Im designing my own motor controller, using an ETEK-R, they now have the ETEK-RT which is even better. The 5.3 was calculated with drag co-effs of a sportsbike, hayabusa i think it was + 1kw of rolling friction. Theres a discussion in the custom projects group on it, and ill chuck a thread up once shes going

This is kinda spooky, like someone edited out the howling exhaust noise. Good watch tho! Gonna order one in T.I.E?

the jozzbikes ducati sounds pretty cool i reckon, and handling wise, the center of mass can be lower, and all the mass grouped close together making it pretty nimble.

I reckon LED headlights and running lights are the way to go, less than a hundy watts all up.

Yeah I was thinking that too. The current draw for LED indicators would be next to nothing, the tail light could be a bunch of LEDs flashing at different rates, and the same in front with white ones for daytime use. Just need something a bit shinier for seeing where you are going at night.

Nice... id be allright out here in the desert if i had a few solar panels on the bike. ill take two (dont wanna be greedy.)

LED headlight is probably a waste. Quartz Halogens get a similar amount of light per watt than all but the most efficient (and expensive) LEDs and are a hell of a lot easier, no controller required or anything (you don't want to use a ballast resistor otherwise you'll use more power than a bulb by a long way).

For the indicators, LEDs are definitely the way to go.

Either way, it is going to be less than 100W all up, so barely a drop in the bucket...

They sound like the RC car I had when I was 14.

Very interesting....

DiD a bit of a looksee when me anD a mate lookeD into electric gocarts.

Still not sure i'D sit on those batterys..... if the go bang..they"ll really go bang.

As opposed to having a tin can full of petrol sitting on top of a hot piece of machinery sitting a few cm away from your crotch?

lifepo4 batteries used in the high power EV's are very different form the lithiums you find in laptops etc, in that they do not explode! Though i heard this from a guy selling the lifepo4's
