KillaCycle builder nearly kills himself

**Roj** · 15th September 2007, 19:21

Ignoring the idiotic stunt, quite a machine he has built, the are vids and stuff on the website: http://www.killacycle.com/

it does prove that electric vehicles can be fast and powerful, but I think he would have been better off making something more practical as it would be cheap to run

Feck I would never buy one. Dont care how fast or how 'kind to the planet' it is.

Half the point of a bike is the sound... having an internal combustion engine between your legs with more horses than a flipping stable.

You cant even "start" it ! Wheres the fun in that??

No way.. would be heaps of damage.. and he surely would have been bleeding from his head at least.. that would have smacked the ground with no lid.. being the weight of a bowling ball.

Um! Too many questions! Why this stunt? What kind of interest would they be wanting to stage something so dumb?

Looked to me like it was genuine and he just didn't expect it to grip and go! Not smart, I agree, but can't see it being staged.

Somewhere there's a story on 500hp MotoGP electric bikes under development...

See your point... but... have any of us heard of this 'bike' before the crash vid was splashed all over the internet??

Yup! It's been around a while, was doing demo runs at a drag strip in the States and has been posted on the net on other bike forums. Very impressive times around 10sec 1/4's. It's the genuine article. Main problem has been traction due to the max torque at zero revs nature of electric motors.

Though of course lack of traction wasn't the problem in this vid...

Hoax. Guy lies on his back and complains that it hurts...Gimme some blood and guts and I believe the guy.

Do electric bikes have clutches? Or are they direct drive like most electric cars?

Might explain why the poor guy didn't just pull in the clutch.

Right! Electric motors don't need clutches. Apparently he was compaining afterwards that the "throttle" stuck and he couldn't kill it, so he was literally taken for a ride! With acceleration like that thing has there's no time to react!

Big issue with electrics where the circuit contacts are constantly being opened and closed is "sticking" and burning, so if there is any corrosion or "gumming-up" this can occur.

Go look at his website, he said he managed to slow it down to about20mph before it hit the car. He said in the interview he doesn't pilot it down the strip, so to my mind it just looked like a fuck up by a nooB.

Watching the youtube vid on his site, it looks like they do run a clutch, so the princaple is the same as a normal bike, wind it up, and launch the bastard. There are serious advantages in electric power for the drag strip, with a perfect torque curve, (or lack there of), and a theoreticle no limit of revs on demand. If you can keep increasing the current, a perfectly balanced motor will just keep pulling untill you run out of balls.
