The Fabike (Front action bike)
actually is the most natural bike, really fitting the shape of our
sitting human body.
It also is the most simple bike one can think of, I think.
The first bike was looking like the Fabike a bit. However, in that first
bike, the crank-axle coincided with the axle of the front-wheel.
Problem then is to construct a gear mechanism in the hub of that front-wheel.
Without such gearing, the distance one covers in one rotation of the
crank-axle, only is the distance of the circumference of the front-wheel.
That is why one started to apply very tall front-wheels. However, such a high
bike is unsafe and uncomfortable.
I think that gear-problem was the most important reason to choose for the
back-wheel driven bike we all are used to now, so with the crank-axle between
the two wheels. By varying the diameters of one or both cog-wheels, one then
can easily change the gear.
But it is a fact that a front-wheel drive better fits the shape of the
sitting human body.
The gear-problem has found a simple solution in the Fabike, by placing the
crank-axle in front of the front-wheel, so that one can use a traditional
gear-mechanism. Actually, one can mount a traditional back-wheel in the
front-fork of the Fabike.
That also results in a better steering quality compared with that first bike
wherein the crank- and wheel-axle coincided. Because forcing the pedals now has
less influence on the direction of the front-wheel.
On the Fabike one can mount an easy seat, and against the back of that
seat one then can push while pedaling, resulting in a bigger force on the
pedals.
An other advantage of the Fabike is the possibility to change it very
easy into a three-wheel bike (for disabled people, as carrier-bike
or as rickshaw) simply by changing the not driven and not steered so simple
back-wheel by two simple wheels on both sides of the back-fork.
The picture above shows such a three-wheeler, when you point at it with your
mouse.
The Fabike can also be built much smaller than the traditional bike,
resulting in the smallest possible folding-bike, without a complicated
folding-mechanism.
In an alternative version, one is steering with legs and body,
while the arms find rest on arm-rests fixed on the back-frame.
Probably the Fabike needs a damped steering-device, for example like pictured above.
I am searching for people who want to build such Fabikes. Do you, then
contact me!?
