Heck, that's nothing. Think of the millions spent on drag racers that can't run at full power for more than five seconds. Think how many salaries that would pay!

No derailleur or IGH will perform well if you're not controlling power output during shifts, that is a fact. Even a Rohloff shifts like a piece of garbage if you don't cut power.
And you'll end up damaging it as well, from personal experience.

Re: Ivermectin/Covid info

I've been vaccinated and I am "pro-vaccine". That being said, Ivermectin doesn't hurt when added to any current treatment protocol. Agreed. Nor does zinc, or vitamin C. If people want to take those, great - in some cases they may even help people with those deficiencies. As long as such t...

Re: Ivermectin/Covid info

You are refusing to address the studies that have shown Ivermectin to have antiviral effects, specifically as a protease inhibitor. I agree it works in theory. I have seen no good evidence it works in practice. There have been several studies that have suggested it helps increase survival rate. All...

For those specs the Grin solution (All-Axle motor, Phaserunner and Cycle Analyst) would work well. The All-Axle is a bit lighter than most direct drive hub motors out there for the power they put out.

Re: Ivermectin/Covid info

Using Ivermectin for Covid-19 is not an unreasonable idea at all. It's neither reasonable nor unreasonable. It's like taking aspirin, or hydroxychloroquine, or zinc, or going on 100% oxygen, or prayer. All those things might work. None of them are unusually harmful. Heck, if you have worms. ivermec...

Re: Ivermectin/Covid info

Ivermectin didn't win a Nobel, Satoshi Ōmura did for co-discovering and developing the compound. And my point is that that means zero in terms of its effectiveness against COVID (or cancer, or strep throat, or infertility - or anything else it wasn't intended to treat.) It is, of course, very effec...

Re: Does my brand new hub motor have a bent axle? (4K video)

That's the part I don't understand. If the bending comes from the axle mount point, which is somewhere around the base of the cassette mount, nothing except making the axle perfectly parallel to the axle on the other side would take out the wobble. If the axle is bent, then you wouldn't get a cycli...

I'm not sure I understand what you mean. It seems like you are saying what the AKM "engineer" said,"finish building the wheel, it will be better". I just don't understand how a rim and spokes would improve the fact that the axle bends the dropouts back and forth. If the wheel ri...

Re: Does my brand new hub motor have a bent axle? (4K video)

I have never owned bike motors before, but this does not seem like an acceptable manufacturing tolerance. Keep in mind that that is the wobble at the hub, not the rim. If, after the wheel is built up you still see that sort of wobble it's unacceptable. However that's not a given, especially if the ...

This type of comparison is a little disingenuous. Gasoline car fires are almost always due to accidents or poor maintenance.

Anybody have any experience with a brushless controller/display combo that works well, handles 500+ watts, hopefully works on 36/48v? Perhaps you can tweak some settings yourself?
Any reason you haven't looked at the Phaserunner/Cycle Analyst combo? They are about as programmable as it gets.

Given that the blackouts last time were caused primarily by fossil fuel plants failing - it won't be free of blackouts while it relies on fossil fuels, either.

Some people are able to learn from other people's mistakes. Some people just have to make the mistakes on their own and (hopefully) learn from them. The important thing in either case is that they learn.

Your suggestion works well enough as long as a relatively large battery pack accompanies it. Nope. Same-same. You don't get any magic "more power from fewer cells" by tricky combinations of S and P parameters. You just get a voltage (via the S parameter) and the current/ampacity you need ...

Re: How do you think solid state batteries will change how we use hardware?

But for something like an ebike or e-moped they don't have a lot of capacity per combined vehicle/rider weight or capacity per vehicle power. So for ebike or e-moped switchable voltage and amps makes more sense than single voltage. IMO you are still better off choosing the right voltage/battery/con...

Re: How do you think solid state batteries will change how we use hardware?

Yes, the 36v 40 amp is better at low speed and the 72v 20 amp is better at high speed. If you have a 36V battery with a given motor and you want to go faster, then yes, going to 72V would allow you to go faster. However, a better design choice would be to choose a voltage, a controller and a motor ...
