Motorcycle 3 wheels – Rondinaud design A.3.W. Reason

A concept motorcycle 3 wheels. The idea is not new, and even very old, because as you will see when I have repatriated pages, Russia had developed machines in the years 50 and especially to move on snow…

But here, when even the & rsquo; idea is well thought, a central wheel for traction, a directional front wheel and axle 3 to & rsquo; back in free management, thus a 3x1x2, that n & rsquo; is not really common for a motorcycle, and not much longer that & rsquo; a classic motorcycle. And to cover all, it s & rsquo; acts d & rsquo; a French project !

The concept of The A3W based on the idea that pleasure and dangers of motorcycling are inseparable.
This machine solves most dynamic problems of traditional motorcycles.
The driving energy is channeled, it becomes exploitable.
The handling of the angle is more accurate and adhesion losses do not involve falling.

Braking meanwhile is safer, more stable, more natural.
It does not demand a great driving experience to be able to operate effectively.

These innovations do not harm the sensations and pleasure that a motorcycle.

The principle of 3 In-line roller is easy to add the third wheel compensates for wheel grip losses among them which is not the case on a 2 wheels.

The Architecture A3W is around a frame Aluminium billet which supports 3 independent operating arm wheels.
The front wheel is Director, it is connected to the handlebars and directs the entire vehicle.
The central wheel is driving it is connected to the motor via a chain drive
it is also attached to a single arm for easier removal.
The third rear wheel is Auto-directional it is that which increases stability and grip, through its hub in free hunting angle
enabling it to monitor and compensate for movements of the machine.
