Re: Dirt Cheap DIY eBike

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...

Re: The food we were designed to eat- Dr. McDougall-very low fat diet( page 8)

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...

Re: The food we were designed to eat- Dr. McDougall-very low fat diet( page 8)

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...

Re: The food we were designed to eat- Dr. McDougall-very low fat diet( page 8)

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; ...

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.

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 ...

Re: See a lot of inexpensive brushless hub motors nowadays (hallomotor etc) are these any good?

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...

Re: The tipping point is just a few years out

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...

Re: Newbie looking for diy rear rack build ideas.

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...

Re: Looking for a chromoly rear rack, any suggestions?

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...

Re: Animation for High Torque ETM motor

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...

Animation for High Torque ETM motor

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...

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...

Re: See a lot of inexpensive brushless hub motors nowadays (hallomotor etc) are these any good?

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.

Re: longer range (over 100 yards) wireless vibration alarm?

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 ...
