Yep... here it is :bowdown:

:laugh: ... cool!
My favorite part is the range of up to 30 miles, riding economically. I'm not sure what "economically" means when the top speed is 50 mph!
(and as it stands now, electrical power generation almost always requires a fossil fuel of some sort; haven't gotten rid of the oil companies yet :icon_rolleyes:)
Here in PA Wind power is HUGE! My nephew works for a MASSIVE wind turbine co. Gamesa. The new house we are building will have a Windmill capable of generating enough power for 3 homes :thumb: No Oil for electricity here :thumb:
:o did you see the size of that rear sprocket.....
I like the old school rear suspension "down grade" :icon_mrgreen:
I love EVs but it's sad to see a GS turned lectric.
hey scott, what if no wind? does the home have/will have batteries to store generated electricity?, and meh if i wanted to go 50 id get a scooter. i like EV's as well, but not with a 30 mile cap ( riding economically ) as teh site suggested. lol i wonder what would need to be fabbed to fit a bicycle style derrailleur on the rear. aka ghetto-rigged tranny. or the day solar cells can be made small enough to cover a bike. and power it indefinately ( or until dark)

Its hooked to the grid as well as battery and solar :thumb:
Right now PA has some GREAT incentives and even grants to "build green" So we are putting everything we can into this house. Its all still in the planing stage. The land has been bought and house plans semi done.
The wind turbine will also be able to sell back enough electricity to the grid at peak times that it makes the down time free :thumb:

Sounds good!
Do you have lots of property, or will the turbine be near the home? How long do you figure it will take to recover the investment in a turbine?
the wind turbine...is it the old school kind that resemble an airplane prop. or is it some of the new kind that resemble a combine thrasher stood on end??
Ditch those lead acid batteries and DC controllers.
Go Lithium Ion and medium voltage polyphase AC. A lot of industrial VFD's have direct access DC busses now. Get into the box, ditch all the rectifier crap, add cooling, make a smaller box, install in bike. Then you have power ramping, dynamic braking, torque multiplication, and all kinds of other cool features. A little more work and you have traction control too!
Ditch the rear brake while you're at it and replace the master cylinder with a braking potentiometer. Oh, belt drive too!
Take a high efficiency three phase inverter duty motor and lighten it up. Make a new base, frame, end frames, etc out of aluminum. :icon_mrgreen:
How about 40-50 HP continuous and 300-400 HP when you let 'er rip eh? Plus 500%or more starting torque? No transmission to shift either.
I just want to be able to say to a Hayabusa rider. "I'm going to hand you your ass." and to his friend "Here, hold my extension cord." :laugh: :laugh: :laugh:
what?

kind of reminds me of the guy who posted using ammo boxes as saddle bags on his bike :cookoo: and what is it with that huge rear sprocket? i do like the paint scheme and think the gas tank could have been made smaller. but now lets give credit where credit is due. electric vehicles are still in the early stages and those who are brave enough to venture into this arena are making inroads that should benefit us all in the future. but it is fun making fun of them too :)

I have 10 acres. It will be split into (2) 5 acre lots though. Due to allot of new windmills springing up here, there are some new codes. So it has to be kinda far from the house. and by putting it on another lot its kinda a loop hole :icon_mrgreen: It costs about 10K including the footing, connections and install. we get about 1K back in federal taxes and have lined up grants to pay for nearly half the rest. Looking at our current heating and electrical bills we will have paid for it and the solar in less than 15 years. If I get some low cost electric vehicles and fuel stays as costly as it is, it will pay for itself in less than 10 :icon_mrgreen:

Speed reduction. He likely needs a decent reduction to get into the motor's sweet spot, much more important with DC motors.
Here ya go...

Speed reduction??????????????? Yeah.........that translates into whatever "mommy and daddy government" has dictated as to what you will "go" in miles per hour. "They" have it all figured out for you. Just relax and do what they say. Everything will be alright. "They know what's best". You'll see this take many forms over the years to come. I've seen a LOT since 1964. Precious little of it has been "for the people".

Correct me if I'm wrong, but don't DC and AC motors create ALL of their available torque @ 1 to infinity rpms ?
If so, then the big rear sprocket is for chain wrap, and I'd bet there was a largish front sprocket also. You know, 50% wrap or whatever to keep things working well.
A 'lectric gs would rock. Light bike, good handling, good ergos for commuting, and the cost per fillup (plus assuming a replacement battery at some point worked in) of around $.30 each ?
Someday, capacitors will have a major storage / charging bump, and we'll all enjoy the smooth immediate torque of electric motors. Imagine a leasing agreement with 'gas' stations where you pull in, and swap out your battery for a charged one in 2 minutes, for $10. Awesome. Never happen in the US though, sadly :(
IIRC, it said front sprocket was 11T :o

Wow, if that's -just- a 10 ft/lb torque motor, that thing is a freaking wheelie machine with those cogs ! Hope the variable pot is sensitive enough to NOT flip it every time you take off ! :D

DC motors generate peak torque at stall, yes. Torque falls off as speed increases, until net torque output is zero at no-load speed. Therefore, gearing is important. Too much of a reduction and it's a wheelie monster with little top speed. To little reduction and it's a fast bike, but slow to get there.
(http://lancet.mit.edu/motors/colorTS3.jpg)
AC motors are somewhat the opposite. An AC motor generates torque as a function of rotor slip. In other words, up to a point, the more the rotor lags behind the rotating field, the more torque is generated. That point is called the Break Down Torque. Increasing the load beyond that point will cause a rapid loss of rotor speed (and therefore power).
http://www.tpub.com/content/doe/h1011v4/css/h1011v4_27.htm
The interesting part about AC motors is that if you vary the frequency to the motor (thus regulating the slip) you can power a motor with a perfectly flat torque curve from nearly 0 to 120% rated output or beyond. The surge ratings can be significantly higher.
Locomotive manufacturers have known this for years. The best measure of locomotive traction efficiency is adhesion. In other words, how much of the locomotive's weight is turned into tractive effort. A 100,000 lb locomotive developing 20,000 lbs of tractive effort has a factor of adhesion of .2, or 20% of the locomotive's weight. 19% to 22% is common for DC traction. However, a locomotive operating with AC traction motors can have factors of adhesion of up to 40%, mainly due to the increased motor control afforded by AC control.
What does that mean for motorcycles? Imagine a bike with smooth, effortless power. ALL of that power is available ALL the time. In fact, the variable frequency drive will need to have a ramp time, otherwise the machine will wheelie instantly. Traction control could be incorporated very easily with existing industrial VFDs, regulating wheel slip even during cornering. Rear braking would be dynamic with traction control (no more locked rears, ever).
Oh, yeah. The motor and control should outlast the frame. Just grease the bearings every 10,000 hours of operation. :)
Nuts. The dude beat me to it. He is running the same motor I planned to put on my conversion.
After running numbers on weight and using one of the EMoto spreadsheet out in the EV community, I decided the GS was too heavy to get any range.
Weight, wind resistance, and system friction are the killers of EV performance. I am considering a composite GS chassis...but then it really wouldn't be a GS anymore would it?

I think it would be if the composite chassis was molded in the shape of the GS frame :icon_mrgreen:
