Electric motors are not so different from gas engines. They suffer from overheating. They have torque curves etc. Most high tech gas engines are controlled by an electric ECU and if the motor/engine is electric this can be made super responsive.
Having been around electric driven stuff for years I know too well the weaknesses and strengths. For daily commutes, deliveries, and short trips the electric vehicle is very cool for many reasons. As for performance its relative to the application.

But something tells me once electric cars get good the cost of electricity will increase inline with the cost of Gasoline. Bastard capitalists!

torque curve is generally a torque flat line, but i see your point. The only major difference (once they sort the energy storage) is the lack of sound.

Just read this in the TT forums:

"RE: TTXGP

Well I have just witnessed the first TTXGP practice and it went well
102 on Sulby straight and and average of 80+ is a great start

and what a reception from spectators! "


Averaging almost 100mph around there would not be bad for an electric bike. Wonder how flat the batteries where after this practice. These things might have a bit more in the tank yet!

Practice results reports etc here:

Interesting Paul Dobbs is riding the 10th qualified bike.

To be fare a 80mph+ average is hardly exciting particularly when you consider Hugh Anderson averaged 96.82 mph back in 1966 on a 125.

just watched some ttxgp footage (would like some more if anyone else finds anything) from the main website http://www.ttxgp.com/index_nav.php?page=livecams, was quite impressed. Sure the power is down but technology will overcome that eventually, the bits i was impressed with was how similar it is to normal bikes, there is still the motor sound, albeit in a slighty different frequency, bikes look much the same, handling is much the same apparently (bikes slightly heavier though i think) and the team agni rider sounds like he had a blast.
I cant wait to have a go on a proper electric bike

And even worse when you consider Glen Curtis was doing 136.4 MPH in 1907 (Over one hundred years ago!).

Good thing they aren't solar powered aye!

Cool link. Interesting to read that one of these bikes is running Lithium Polymer Cells. That would be interesting if the pack decided to ignite itself due to high load or some other cause.

Hate to let the facts get in the way of a good story but 1907 results were

1907 results Charlie Collier 1st Matchless total time 4hr8min8secs avg speed 38.21mph in the single cylinder race 17 starters 8 finishers
and
Rem Fowler Norton 1st 4hr21min52secs avg speed 36.21 mph in the twin cylinder race 8 starters 4 finishers.

No mention of a Glen Curtis, assume you are talking IOM or otherwise a bit hard to see relevance?

huh??? why?

Sorry Rocketfish.

I was struggling to see the relevance of Hugh Anderson on a 125 in 1966. Like what speeds where the electric bikes doing around the TT circuit in 66?

Thanks for pointing out that the first petroleum propelled bikes where heaps slower when they first appeared at the TT.

[GSVR]

You do chemistry at school? Lithium burns like magnesium ribbon. Or just search for lithium fires somewhere.

Probably the biggest advantage the A123 cells (Lithium Nano Phosphate) have is they are very inert.

Or where you asking whats interesting about the page?

What gets me is Ok zero emissions, but with a world of battery powered just about everything, what the F**k do we do with the battery's when they come to there life's end, throw them in land fill's. Wheres the Green in that.

Interesting question. And theres many angles to this.The old battery technolgies where very bad for the inviroment. Heavy metals like lead and cadmium where bad but lithium is pretty safe.

One aspect of an electric car is no oil changes and waste oil. Not seen on these bikes but I'm sure eventually no brake pads to wear out and the engines wont wear out either so no where near as many wreckers filled with steel that needs to be resmeltered. Maybe manufacturers will make cars that last as long as other electrical appliances.

Only issue I see is the production of huge amounts of electrical energy. Coal fired power stations would defeat the whole purpose.

Would be nice to go to an electric race bike meet and not have to ever worry about a crash that leaves oil all over the track. And if these bikes can already do a lap at the TT they could do the average race in NZ easily already. And if the races where half as long the performance would alot higher as half the battery capacity could be used or twice the load on them could be achieved.

I think it was stated the winning bike cost $30000US to build. All the expense would be in batteries and drive.

find ways to recycle the batterys, most of the chemicals in them can be reused/revitalised again i believe

Zero emission when they are running but what about the emissions required to generate the power required to charge the batteries, make the batteries etc if everyone wants electric everything. Hmmm nuclear power required

The problem at the moment is two-fold and evs will solve at least one.
1) the petrol supply is running out, and if we dont have an alternative the human world will be seriously fucked.
2) human pollution is fucking up the nature world, and if that shits out we are done for too!

so even if they just move pollution somewhere else they are still saving the world, and localising the pollution sites will also make them easier to deal with, or just move them to the moon or summat.
