Climate change”, invented by the corporate news media to cool down “global warming”! It should be called “life support system collapse”. And all that people can worry about is paying for their big house and cars. Transportation is nothing compared to what problems the human race will encounter in the next few decades.

If human life is going to have a chance to survive, much more will need to be done NOW!!!! Start by killing your television, it is full of fascist lies! Watch these videos by Paul Ehrlich and Chris Hedges etc. Then tune into web sites like 'the real news network'.

Some people think that we will be able to buy our way out of this existential crises. This is the way of denial; false hope! Only the plutocratic top ten percent of the 'one percent' will be unaffected. They are like God kings to the rest of humanity.

The only real hope we have is for people to start to work together like an army to change our fuelish “way of life”. Get a grant, Build cargo bicycles out of recycled mountain bikes, give them away for free!

Dissolving wall street would do miracles for the world, but if you think that will ever happen, you must be on the better drugs than I am!

Cargo bikes will play an important role in the transition to a life style with less entropy, but it will not happen with out you getting involved!

eBike Burn-out?

People tell me that  all e bikes burn out (melt down). This is not true, the reason most burn out is simply that most people just over power their equipment. If one would use a programmable controller you could keep your equipment from over heating.

How ever you can learn to use a cheap one with out red lining it. and keep all the connections lubricated with Vaseline for good contact. Unfortunately most people want to hot-rod their equipment.

Bicycle shleter roofs for wet snow

 Bolsheviks unite! Agitate for better bicycle parking!

The roof is the hardest part.... gotta keep it light weight to be moved around.

 An inverted triangle is more stable than a triangle with the apex on top.

ELF car

One HP hub motor, not on the drive wheel. Possibly the only motor that will fit in the tight space. The power from the motor is not geared down by the Nuvinci  gear hub, but the infinite gear range of the Nuvinci does help you match your pedaling force with the motors force.

We have steep hills  and two children that keep getting bigger and bigger, so I would need a larger motor and a second stage gear reduction. A two speed gear box would be ideal.

But then the wheels and frame are rated for only 500lbs? (150lbs plus the payload.)

Two large lithium batters, but a third one would help with climbing steep hills.

Rear hub; Needs a larger sprocket for a lower gear, but the brake is in the way.

right side of motor

left side of motor



front axle

the pedals need clips

I would rather have something that looks like this, but with three wheels and a tilting system.

or like this but with out so much power! People are insane to want so much speed.

slow it down!!

Expanding chainrings born again

These were made for may years and used for commuting successfully, But bike racers did not like them so they stop making them. Another perfect example of how the Racing industry has turned bicycles into a disposable aluminum junk yard.

The new one:

The old one made of steel too heavy for modern man, weak form driving cars!!

Another Concept trike

I have not seen much info abut this, but concept designs are usually not put into production, nor even a prototype is made.  I would like one of these my self, maybe I can build one my self.

 Gears in the rear? suspension in the center? Does not lean like a bicycle? Yet has a high center of gravity. Is that safe? I would build the front wheels wider apart. And I want to see the Ackermann steering in action.

Cargo Bicycle Design Contest

The winner will receive a painting
The bike must be easy to build  and easy to get off of when fully loaded, (some people do not under stand the need for a low step through frame); and sitting up straight is needed for carpel tunnel syndrome.

And the design must be original!

Actually I do not expect any one to do better. Because it took me years to learn how to construct a bicycle from used bikes, with out a shop.

Based on this design concept, I have another winner

I do like leaning trikes and other cargo bikes, but not for ease of construction.

The history of safety bikes

In the beginning there was a wooden two wheel cycle with no pedals, made to help french solders get all there equipment down a hill fast with out running and falling.

Then the high wheel bicycle so riders could go faster and crack their heads.

Finally some one invented gears so the rider would be safer, closer to the ground. Unfortunately racers found that by leaning forward they could go faster and crack their heads.

Yet people still crack their heads even on the old style sit up straight safety bicycle because they want to go fast! Now with motors!

I have know several people that have smashed their heads riding road bikes. I will never even consider riding head first.

I never wear a helmet because I know how to ride a recumbent bike. Road bikes  are not 'safety' bikes!  

 Speed is the biggest danger factor. Two of the people that I know died from cycling was from too much speed. An Olympic cyclist in training on the local roads flew over a cars hood into a barrier when the teenagers decided to turn in front of her. Then there was one man I know that ran into pipes sticking out of a truck because he had his head down.

heads crack like eggs

Too many gears!

Now you can have a 3 speed hub with an 8 or 9 speed cassette, and a disc brake! They say you can remove the multi-speed crank set. But in reality the only way to get a low enough gear for a trike to climb a 16% grade with about 300 lbs total weight, is to use 22 sprocket chain ring and 34 sprockets on the rear, that would be about 13 gear inches for a 26 inch wheel and 10 GI for a 20 inch wheel.

It would much cheaper to use a Mountain tamer fourth chain ring of 18 sprockets in the front, equaling 10.5 gear inches.

Sram dual drive 3 speed with cassette

Sturmey Archer F30 rear 3 speed disc brake 9 speed cassette

These are best used on trikes because bicycles can not be ridden under 3 mph! But it will allow a trike to be ridden up some very steep hills.

Bolt together trikes

So how does it keep from rattling apart? Even stainless steel bolts come loose. Carry wrenches?

Plans for the recumbent trike only...$2000 plus shipping!

The Copenhagen wheel?
This is  a self contained, but wimpy  machine, made for people that live on flat land, and need to stay dry cycling to work! But do not think it will carry you up steep hills with cargo!

While a single stage chain drive loses around 5-10%, a hub drive not operating near it's peak RPM is losing far more power than a properly geared motor would be.

San Francisco wheel?
If some one wants to make a dent in america's car culture glut, they are going to have to engineer one that can drive 400lbs up a 10% grade at legal speeds. It has the potential to use thicker wires for lower voltages when climbing hill, unlike normal hub motors, with out planetary gears.

Only in america can we use a motor strong enough.

Milk Crates

Some asked me the other day where to get one and I had no idea other than a junk yard. apparently they are available several places on the net.

Even on

Ergonomics of carpel tunnel syndrome

I spent 10 years with painful carpel tunnel syndrome, and almost gave up on bicycles. I got a recumbent trike and finally a recumbent bike. But I never like how hard it was to climb hills with cargo.

Eventually I found out about the ergonomic power angle when I was designing a batter recumbent bicycle. Recumbent seats are set at about 35 degrees off a line from the cranks through the back of the seat, with 5 degrees of adjustability each way.

Then I noticed how old cruise bicycle seat posts are set at 60 degrees off the ground. This angle lets you sit up straight and take the pressure off your wrists.  And still sit at a 30 degree angle from the crank spindle, and lean forward to about 40-45 degrees.

Mountain bikes are set at about 70 degrees, which gives you a 20 degree ergonomic angle. That is why I stopped riding regular bikes until I rediscovered this system of taking the pressure off and still be able to lean in to the pedals when climbing hills.

It took  special handle bars to be able to grip at two different places.
