Motored Cycle-Truck vs Fast bike Fetishism

What is the difference between a motorcycle and a 600lb utility bike?
If you think it is the power of the motor, you are wrong!

  • One has the ability to drive faster than 20mph on flat land. A motorcycle must be able to drive at least 45mph on flat land, and is engineered with fantastic brakes to handle the increased power. Usually two large hydraulic brakes on the front wheel.
  • A bicycle will never be able to stop with that much power. Rim brakes are useless and cable pull disc brakes are not much better, even with metal sintered pads!
  • And if you did make the wheel stop turning the top heaviness of the vehicle could make you loose control too easily. Not really a problem for off-road bikes because that is exactly what makes it fun.
  • The cycle-truck has the ability to climb hills with a total combined weight of 600lbs with only one single gear; Set at a slow enough reduction ratio (about 12mph or less) to climb your worst hills with the most weight you will need to replace a car.
  • People that think gears waste energy, are brainwashed by speed merchants. (ie: sellers of hub-motors that are built for racing, not for stop-n-go city driving.)
  • Some states make you use a pedal actuated controller, to make sure you can't drive over the speed limited by law. But gears them self's can limit the vehicle's speed.

People that wait until it is too late to change their life style will pay for it the hard way.

There is no reason that people can't start changing their transpiration methods now.
Electric bicycles that can move 600lbs up our steep hills can replace a car. Obviously not many people know how to build these. But I do! Read my 13 year old non-profit blog about living with out petroleum powered vehicles!

Most people lost their ability to think creatively in school. We were taught to memorize data like a machine. If you want to learn to use your brain fully you have to learn to think “laterally”.

Electric Utility Bike

This is the best utility bike frame I have seen yet. But it does need a rack welded onto the front of the frame. And a motor mounted low under the seat, to drive the rear wheel. Hub motors are for flat land only!

The rear rack should be long enough to hold a large size milk carton box. Once you have more carrying capacity you will want even more. Also a ladder rack on the side, would be very good to have.

An easy step-through frame is essential for a fully loaded bike! This fork design is for strength rather than travel, it is not an off-road suspension. But excellent for riding off curbs and pot holes. And at high speed, if you hit a pothole with a heavy load on the front, you could end up with broken spokes or even a dented the rim.

The front wheel will be easier with a drum brake hub. Rim brakes or a disc brake will be difficult to apply to the front suspension with out a jig. And be sure to use the widest rims so you can use 16” Moped tires.

The slower you ride the shorter the trail should be. I had to change my recumbent to half inch trail because I really noticed wheel flop when climbing hills too slowly. My utility bike has 1.3” trail. Any thing over 2” is for fast cruising.

Wheel chairs ment for travel

A wheel chair that is also an all-terrain trike. The arms ratchet the wheel gears forward. It could use a motor on a Jack-shaft or two hub motors but you won't get any exercise that way.

There are a lot of “concept” vehicles. Most never get funded because the designers have no knowledge of what it takes to actually build one. I would like to see more concepts deigned by engineers!

This one is for people who still have the ability to use their legs? There’s a version of this wheelchair that is steered only with the arms, but we couldn’t find any images of it.

MTB to e-Road bike:

full suspension longtail cargo bike in video


Converting a mountain bike to a electric road bike, is not has hard as you might think. Hub motors climb hills with cargo much better when built into a 20” wheel. And they need suspenstion.

  • Steel Suspension MTB frame made for 24”-26” wheels. Make sure that it takes a disc brake in the rear.
  • Longer spring loaded oil shock to push the drive axle down about 3 inches. But you may not even need as much road clearance for the pedals as on the MTB. And you could to get 155mm cranks arms.
  • Fork for 20” wheels. It may need a longer head tube extension welded on.
  • 16” x 2.25-2.5” (21” o.d.) 4-ply Scooter tires will fit on a 1.25” bicycle rim.
  • Wide bicycle fenders are a maximum of 2.25” wide for 26” tires. They bend easy with only a little heat.

I put a 19” (23”o.d.) x 2” wide moped tire on a 19”motorcycle rim for my MTB-cycletruck frame made for 24” tires. So a 17” x 2.5” tire would probably fit fine with out lowering the crank too much. Measure the clearance for a 2.75” wide tire.

Do not put a larger diameter tire in front than the rear unless you can keep the steer angle the same. If the trail increases with out more rake, it will cause steering problems (wheel flop).

what they don't want you to know

Is this cynicism, naiveté, satire, or just the unbearably horrifying truth? It all depends on how passive you are.


'Interstate cross check' is how they stole the election. Thousands of people's votes were thrown in the trash just because there were people in other states with the same or similar name!!!! So now if you want your vote to count. You have to change it to a totally unique name, one that no one else the US has!

And the media like fox TV gave him something like 3 billion dollars worth of free airtime.

What happens when the rich are confronted by a truth-teller politician (Bernie Sanders)? They had to pay a 
Neo-McCarthyist con-man to sell austerity by demonizing 'foreigners' and the 'social safety net just so they can shock us into confusion so we don't know what is happening. Bypassing the rational side of our minds! Mind control works best on people that are dependent on the money system.

Crashing the economy, defunding education and the social safety net just so they can say it is broken and needs to be privatized will only serve to accelerate Capitalism’s end.

Even now many people fail to grasp the true meaning of the word “austerity”. Austerity is not eight years of spending cuts, as in the UK, or even the social catastrophe inflicted on Greece. It means driving wages and living standards down in the western world, for decades until they meet those of the middle class in China and India on the way up.

How Capitalism Is Dismembering America

Politicians trying to shift the blame away from their financiers have referred to the lowest-income 47% of Americans as the "takers," who enjoy government benefits at the expense of the high-earning one percent. But their claim is meaningless. The total amount paid out in 'welfare' (Temporary Assistance for Needy Families) is less than the investment income of just three of the most rich in a single year.

Market capitalism is predicated on a set of presuppositions that are simply no longer viable given emerging technology. Everything the market expects in it's system structure, is being made obsolete. Think about customized Printable devices.

“Neo-liberalism” has morphed into a system (neo-fascism) programmed to inflict recurrent catastrophic failures . Class assault on the poor is disaster capitalism's “shock doctrine”!

Most of us have learned helplessness. Which means they will do nothing; not even passive resistance is possible if you believe that nothing can be done to stop them. The only chance we have, is to take charge of our own life support system in a collective structure.

The coming wave of automation, currently stalled because our social infrastructure cannot bear the consequences, will hugely diminish the amount of work needed; not just to subsist, but to provide a decent life for all.

However free information is corroding the “market’s” ability to form prices correctly. That is because “markets” are based on scarcity while information is abundant. The system’s defense mechanism is to form monopolies (coemption) of socially produced information. Constructing a fragile corporate edifice at odds with the most basic need of humanity, which is to use ideas freely, helping imperial capitalist's grasp on our economy collapse.

A whole business subculture has emerged over the past 10 years, which the media has dubbed the “sharing economy”. A good example would be a “recyclery” or a small garage business that re-configures recycled bikes into utility cycletrucks to give to people that will use them inplace of petroleum powered vehicles, or making them for a bike share project; subverting consumerism!

The old business paradigm of selling services without sharing the knowledge of the parts that can be done by the buyer, is on its way out! If communities can't learn to work together they will not survive!
Mainstream economics proceeds from a condition of scarcity, yet the most dynamic force in our modern world is abundant information. 

Market imperialism (neo-fascism) justifies it's existence by the recognition of the need to manage scarcity; but due to it's structural mechanics, actually promotes and rewards infinite consumption.

The business models of all our modern digital giants are designed to prevent the abundance of information.

Information is a machine for grinding down prices of things needed to support life on the planet. It is the “externalizations” of un-ownable information, and well-being generated by networked interaction and the rise of subculture production that will subvert repressive neo-fascist capitalism.

If we cannot implement a functional system built on abundant information, non-hierarchical work and the dissociation of work from wages; as well as force the imperialist banks to stop creating “Fictitious” capital. We will all suffer the oligarchy's plans.

The Libertarians are actually telling their followers that intellectual property should be protected. And that the “market” forces will sort things out and bring freedom to all of us, not just the oligarchy. People will believe anything, if you keep repeating how the Welfare and Medicare social safty-nets are broken. 

  • First, he will install import tariffs.
  • Second, the the jobs created by this will not be high paying enough to keep up with american produced goods.
  • Lastly there will be trade wars and finally shooting wars.
  • Worker co-ops are the only way out of this death spiral, but it will take many years for the transition. The British Worker's Party understands this but americans are too brainwashed.
Global Capitalism Trumps Plans for Jobs, Taxes, Trade

What is next for our so called democracy?

Crisis cults unleash further collective delusions; believers entranced with magical thinking.

Or just more demonizing of the disabled and poverty stricken to distract us from how the corporate fascists are controlling our minds? Psychology of control, State of Mind

The end of capitalism has begun

Hub Motors for Cargo bikes?

This is the right place for a hub motor
 but a second drive chain is needed

You could use one of these YubaMundo mid-mounts
without the jack shaft and sprockets that are there
just to drive from the left side over to the right side.
But you will still need a sprocket adapter that
fits onto the free-hub body on the drive wheel,
to use a stronger #35 chain. And mount it behind a
5 or 6 speed cassette. But if you’re looking for
maximum efficiency, use a LightningRod's kit
To run only the axle there is a complex operation
If you are thinking about a Stoke Monkey mid drive
consider this. This graph is done in a low gear
 and an even lower gear will work better but bicycle drive chains 
were made for only human power abilitys of about 1/3rd HP, so they wear 
out more often when you use an electric motor strong enough 
to climb steep hills with cargo. That is why I say mount your
 motor under the seat and drive the wheel through a gear reduction.

The only reason to use a hub-motor is the width, they fit between the pedals.
And they are slower than long motors, making it easier to gear down to the drive wheel.
A 16” wheel is a ratio of 1.6 to 1 of a 26” wheel.

Smaller drive wheels are like using a lower gear. But it is hard to find a cargo bike with a 16” wheel. Mounting the hub motor in the center will let you build a lower gear. You may need an even lower gear for a steeper hill.

You can see from these graphs that it is hard to find a hub motor that will drive you up a 9% grade with 440lbs (200kg; total combined weight) at any speed with a one-to-one ratio as direct drive hub motors are.

Using higher voltage will be like using a lower gear because it allows more wattage with out increasing the amperage (higher amperage requires thicker wires), but then you have to reduce the gear even more because the motor will be moving faster at that higher voltage.

I didn't see any 36 volt hub motors that could climb any hills steeper than a 8.6% grade with the weight that I haul, with a 26” wheel. Although there must be some. Lower gears use much less power than a one-to-one ratio to climb a given hill, so you will need a larger battery with a hub motor. (more money)

If your hub motor seller does not have a graph like these, or cannot understand these graphs, do not buy from them!

Motor simulator graphs:

Converting a hub motor to a middrive motor

eBike school:

At 36 volts the motor is slower but not as powerful

Pay close attention to the Motor Power Curve (Red Line) and the Black Curve (Load Line). Typically the Motor power curve will rise up in an arc, and then abruptly fall off on a straight line down to "0" The highest point (Apex) of the motor power curve is when the motor is demanding the full current output of the controller (and where it is least efficient).

If the Load line intersects to the right of the apex of the motor power curve, then the controller is powerful enough for the system. If the load line intersect the motor power curve to the left of the apex of the motor power curve, then the controller is too small, and we should look for a more powerful (higher current) controller. 

    The black Load Line shows the power required to propel the configured bike at any speed. This has nothing to do with the simulator - it reflects the same results you get from any standard bike speed calculator - basic physics - nothing to do with motors. This is all about aero drag, rolling coefficient, grade, etc.

    The red line is the mechanical power the motor can deliver at any speed where speed varies according to load not throttle. This is based on dyno data and Justin's modeling - this is the 'simulation' part and has nothing to do with drag, grade, etc.

    The intersection of these two lines is the point where the power to propel the bike is exactly equal to the power produced by the motor. This indicates the terminal speed for that bike configuration and load. This is simply a graphic solution to two separate sets of power equations (i.e. it could be done algebraically - the graphic solution is equally valid...)
This means that if you want know how much power it takes to push your bike to 35mph, you just turn off all the lines except the Load Line, configure the bike, then look at the power at 35mph... This is the amount of power required regardless of the motor or drive system. It's only when you play this curve against a specific motor that you get into the terminal speed, etc where the specifics of that motor/battery/controller can be balanced against the requirements of the bike/grade/etc.

For example, in the plot above, we see that it takes about 3200W (motor power) to push that bike to 45mph. Using the same efficiency as shown (86.9%) we see that although it takes about 2680W (battery power) to achieve 40mph, it would require 3200/.869 = 3680W (battery power) to get to 45mph - a fairly staggering increase for 5mph - but perfectly understandable when you look at the steepness of the Load Line at that speed.

do not put a hub motor on the front wheel!
