Ok, y'all have made it pretty clear that you either don't approve of, or don't understand the point of, my project. It ain't a question of approving. I'm all for cheap. You don't see an expensive rack on my bike. You see a cheap one from WalMart that I beefed up. I buy my tires and other parts on s...

Yes. Mayo and my GP both have websites that give access to my lab results. I like this service/feature and consider it useful for thos people who like to independently research things related to their personal health. But I wouldn't necessarily correlate it with general quality of care/diagnosis fro...

Bottom of graduating class? Why, Doctor, of course. Perhaps we’re blessed with The Mayo after all. Everyone of Drs are well versed and quite brilliant. Even the dummies have far more education and skills than any internet’s expert. But I guess I’m just dummer than average for having more trust in t...

That said, a Dr doing due diligence on diet has far more education, time re viewing peer reviewed stdies than you and I will parse in several decades. Careful you don’t throw the baby out with the bath water. I doubt that very many doctors study nutrition to that degree. From what I've seen, a mode...

I'd say as a measurement of how your eating habits are working would be to fast 14 hours then try for maximum athletic performance. If you bonk then you aren't metabolically flexible and you might want to rethink your eating. I've done that, and man have i had some weak workouts fasting that long; ...

Bill, All your examples are the result of a Capitalist system You're confusing him. He's trying to prove that government is the way. Like NASA, nevermind it's all done by private contractors. Saying that the work was done by private contractors rather misses the point - which is that the financing ...

Look, I'm not asking to be pissy or argue. I just always distrust claims of studies and results that are still inconclusive. Reading the Blue Zone studies does nothing to support longevity and keto diets. The problem is that when dealing with humans we have a problem with the kinds of things we can...

I'd say we're omnivores but have genetic variation just like our primate ancestors do. One diet does not fit all.

I've come to pretty much the same conclusion.

But good to see you don't follow the asinine claims that such things are "poison." Agreed. But frequently they are not the best solution and they over-reach in their influence and effect. But that will be the ongoing debate in a probably necessary mixed system. People will tend to disagree on what ...

Wait a minute, what are you guys even discussing? It's not just Bill this time. Well, okay, there's no such thing as 'Mixing in' a little arsnic, (Socialism), fascism, (Cyande), starvation, (Communism), as though you can come up with a healthy mix. Do you even think about how little poison actually...

https://www.ucsf.edu/news/2018/08/411526/ketogenic-diet-gains-popularity-scientists-research-what-we-do-and-dont-know I'm interested in the studies but except for those mentioned above, they seem sparse. Lots and lots of anecdotes in this thread, but where's the beef? I'm suspicious of any radical ...

Sellers want to sell obviously, so what they tend to do is to appeal to the UK crowd of 250W they will list their 500W as 250W. There is no set standard for wattage, not even in the legal requirements. While most definitions are ambiguous and unclear, there are a few laws that talk specifically abo...

The wait for a ride that you say people won't tolerate is significantly less than the time it takes to find public parking in many parts of town. Blinkered old people probably think having their own car is still the most convenient option, but many of the young'uns are not fooled. In addition, your...

Lots of fad baloney in the diet industry. Unless you are trying to deal with an actual ailment or medical condition (like, perhaps, diabetes) the human body is pretty resilient. I've concluded the following, non-ground breaking things about eating. Rule 1: Eat whole foods and don't overcook it. Go h...

My approach posted earlier in this thread has been simple tho probably not particularly elegant. But so far it has been very robust. I just use relatively hefty hardware store aluminum and tubing. I'm assuming it is 5000 series aluminum of some kind. My modified rack routinely carries 35+ lbs on a d...

Something to get by until I can upgrade the rear rack properly. Any ideas? It is generally not a good idea to terminate a strut in the middle of a stressed member. That introduces bending loads. Some tubes are butted, and have thinner middle sections which makes doing that even worse. Though I'm gu...

Anyone bend small steel tubes, like Tubus? Fill with lead or ice or something?

I think sand is often used. I haven't done it though. There are videos on YouTube showing guys doing this ... of course.

However, unless I missed something (always possible) the motor in the video appears to be designed to operate with gearboxes, and/or at higher rotation rates, to get the higher power levels. That's incompatible with DD hubmotor use, unless it's in really tiny wheels, like the hand-sized scooter whe...

We completed this overview animation for ETM earlier this year. The animation doesn't really get into the theory of the motor very deeply at all, but wonder if this kind of design could be adapted to make a DD bicycle hub motor that could have the size and weight of a geared hub but the simplicity a...

Keep in mind that this forum is heavily oriented around DIY (doing it yourself). If that's you too, then building your own is clearly the way to go. You can get more speed and range if you custom build to your situation and preferences. If not, the bike you referenced will probably be a nice fairly ...

This appears to be the same kit at a slightly lower price. I suppose you could have it re-built as 700c, but that would probably not be as cheap as finding a kit already built that way. https://www.ebay.com/itm/48V1000W-26-Front-Rear-Wheel-Electric-Bicycle-Motor-Kit-E-Bike-Conversion-Kit/29197364030...

I've put about 6500 miles on my $235-ish ebay DD motor. It appears to be a Nine Continents 2706 clone. It has behaved perfectly. That said, I don't drive it hard. It seldom sees more than 1000 watts of power and typically sees 400-650 watts. I think the simplicity of design makes DD motors pretty d...

Finding that chainring was hard back in the early 90s. In fact, I made a 72 tooth ring myself for the first go-round. But Mr. Bill at Landis Cyclery on Indian School went hunting through his catalogues. He found the 11 tooth freewheel, hooked me up with the crank conversion kit to get rid of the one...

It isn't the torque that matters. It is the lower rotational inertia. And no, I don't think it would be a good idea for someone weighing more nearly 400 lbs to get on my little ol' Dahon folder. It was less uncomfortable to ride 25 years ago, but never was super-comfortable. But I could carry it up ...
