" Here is a low cost alternative. I've used them on go karts before, they zip right along.
48V 1,800W brushless motor, controller & throttle ($135.00 delivered)

Here is a very "shaky" video with some good info on this motor.

It certainly does.

Another subject that has been on my mind lately is what are the proposed tariffs on just about everything imported from China into the U.S. going to do to electric motor parts, batteries, controllers and the occasional California electric motorcycle company prices? My guess is nothing good. Electric motorcycles and their parts are already too expensive for most of the general market to bear right now. Jacking up prices by 10%, or likely 25% (since the Chinese are not likely to want to "loose face" by caving into "our" demands any time soon) is really going to depress the electric motorcycle market - and likely related markets, too.

" Hi Frodus, thank you for your answer.

I start to think there is something wrong with my charger.

Last time when it jumped the way i described as soon i tapped lightly on charger housing with a rubber hammer charging amperage go higher, as soon it goes down again after next tap ig go up again until it stayed there. For me it sounds like some component at PCB are not very well connected or start to loose connection. Today when i charging again, there was no no jumping at all. It still overcharge according to chosen program. "

" It's a little more convoluted than that, but yeah, mostly. I pulled this section out of Mark Twain's "Roughing It" - his account of his exploits in the Wild West around the late 1800s:

So the thousand wild cat shafts burrowed deeper and deeper into the earth day
by day, and all men were beside themselves with hope and happiness. How they
labored, prophesied, exulted! Surely nothing like it was ever seen before since the
world began.

Every one of these wild cat mines -- not mines, but holes in the ground over
imaginary mines -- was incorporated and had handsomely engraved "stock" and the
stock was salable, too. It was bought and sold with a feverish avidity in the boards
every day. You could go up on the mountain side, scratch around and find a ledge
(there was no lack of them), put up a "notice" with a grandiloquent name in it, start
a shaft, get your stock printed, and with nothing whatever to prove that your mine
was worth a straw, you could put your stock on the market and sell out for
hundreds and even thousands of dollars. To make money, and make it fast, was as
easy as it was to eat your dinner.

Every man owned "feet" in fifty different wild cat mines and considered his
fortune made. Think of a city with not one solitary poor man in it! One would
suppose that when month after month went by and still not a wild cat mine [by wild
cat I mean, in general terms, any claim not located on the mother vein, i.e., the
"Comstock") yielded a ton of rock worth crushing, the people would begin to
wonder if they were not putting too much faith in their prospective riches; but there
was not a thought of such a thing. They burrowed away, bought and sold, and were
happy.

There was nothing in the shape of a mining claim that was not salable. We
received presents of "feet" every day. If we needed a hundred dollars or so, we sold
some; if not, we hoarded it away, satisfied that it would ultimately be worth a
thousand dollars a foot. I had a trunk about half full of "stock." When a claim made
a stir in the market and went up to a high figure, I searched through my pile to see if
I had any of its stock -- and generally found it.

" That Rollo-Ring is a pretty nifty invention, but I don't think applicable here. And gocart chain adjustment is not the same animal, without 6" suspension travel

What I really really need to find is a 520 sprocket adapter for the 7/8" keyed electric motor shaft. Nobody makes a solution AFAIK.
I was going to meet with my local machinist about prototyping one up. I ordered a JT sprocket for a BMW G450X... the inner diameter should fit over the shaft diameter no problem. They are available in 13, 14 and 15 tooth configs. "

" Thanks for throwing a wrench in my sales pitch, Ted!
45 minutes of ride time would need a big battery pack, even with the golden motor, IMO.
But Ted is right, the Golden will be much better than an old 0909 "

" Actually, what I like to call the PT Barnum Effect ("There's a sucker born every minute... you just happened along at the right time"*) is something I mention, though not specifically in the context of today's blossoming of funding prospecting, but certainly what started in around '07 and has continued today. See "Perspective and Context: The Gold Rush Phenomenon" starting on page 70. You may have missed it, because I talk about Mark Twain and stuff... y'know, not motorcycles.

" You certainly are bringing up EV history that I never knew, Ted. Unfortunately my EV knowledge, such as it is, started in 2009 with my purchase of a 2008 GPR-S. That was when my frustration with electric motorcycles started and when I started to wonder how I ended up in that particular quagmire - that I only got out of when I bought my first Zero.

On another subject, that has nothing to do with your book or the thread topic, I check out this site every morning to see what is new: https://electricmotorcycles.news/news/. And there is a lot of electric motorcycle/scooter/weird stuff news that has piled up in that site. It seems like almost every day there is a proposed new electric-powered two-wheel product that someone has dreamed up - and more often than not is trolling for investor dollars. Is the market really that large to make these ventures profitable? If not, what happens to that invested money and all of these people wandering around with more big ideas? Those are the kind of questions that wake me up (but do not put me to sleep) in the morning. "
