so it is possible, also how many ah do you think I need, and also could I use 36v instead of 48v as the rpm will be reduced and the ah will go up.
maybe I don't need 6kw but it would be nice to have more than the confencial 1200w max on the mp.
can I connect a controller that delivers about 50amps con, because 120a continious will empty an 12ah in 6 min. I need to go about 1 hour so if I get about 30ah orso then it could draw 30amps for an hour and 30amps on 36v is p =  u * I = 1080 watts and 4700 rpm.
with gear reduction of 10:1 it would go 470 rpm and that's on a 26 inch wheel a nice topspeed.

so a big motor
controller
servo tester to control speed
5v supply
big battery pack.

how much is this going to cost me

a bit off topic but what about a cyclone 1200w motor or the 1500 double motor for 75km/h or 75mp/h?
i already have a 48v 12ah so it woult just be about 400eur

Just going back to between MagicPie and the 1000W 48V, is it better to get the 1000W 48V? From what I read the MP still has bugs in it and I don't mind taking the extra time to install the 1000W. It's also cheaper. Is there any differences other than this? Also, I have a rear suspension bike. Where can I get one of those racks that just hold on to the seat and not have supports running down to the axle? Thanks!

That is not as sketchy as this one that I saw on a gas bike board though.

He wants speed on a flat, and dependability. Get A GM kit with the GM slide off lithium battery.
My 12V 500W goes 20 some MPH. I have had No problems. I have worn out the tire. I have left it outside in the snow and rain.
I get about 6 hours to kill battery. I will buy a larger kit. I can't go fast enough!

Sounds great! Can't wait to get mine but I think I'll order it once it starts to get warmer and I find a new place to live.

When propellers won't do you need the V2 version.

Talking about a V2...... This is a test I did together with a friend of mine (a blacksmith) Me being the artist with the bright Idears and him being the handy man with all the wright tools . Whe upsized some drawings we found on the net to make a pulsejet for a RC plane 400% and ended up with a giant engine that whe accually got working at a party 2007.

Mounted it on a small cart, hooked it up to a upside down propane tank (liquid propane straight into the engine) And modified an old car ignition to constantly spark to get the explosions going.

Then there is me with the leafblower trying to get some oxygen into the engine to get the explosions resonating  ....
Then 150 + Db and 260 explosions/min

Yes that guy with the wool sweater and leafblower burning his eyebrows is me.

LOL

Well that just reminded me that there are crazy people on all parts of the planet :D

Thanks for the link to Robert Maddox. I live in the same state as him although at the other end, but will have to make an effort to look him up. Maybe not for a test ride but he would be fun to talk to I'm sure.

And as far as you go Jerry that was quite the stunt and I am thinking that it took a while for your eyebrows to grow back after that party ;D

A bit on the tamer side but here is a vid I made of my gas bike, not rocket assist but it gets me where I want to go.

I like both gas and electric but when it comes to speed, efficiency, carrying capacity and range the gas bike wins hands down. Cost is way less also. But as they say, it's all good.
