Since late 1971, the author of this WEBSITE worked on both:
– 2-Wheel bicycles and morotcycles, AND
– 3-Wheel motorcycles.
Hence the numerals 2 and 3 of this DYNAMIK23 website.

Please select one of its two parts that may interest you:

If you hesitate, please consider that:

-1- Bicycles and motorcycles are small, agile and fast in city traffic. Their steering is peculiar, they seem unstable, and they offer little protection in collisions.
But their safety and fun to ride can definitely be increased.
So click on the first link above to:

– Discover a novel steering theory explaining why bicycles and motorcycles stay upright and ride so well.
– If you’re a motorcycle rider: Discover a technique enhancing steering precision, safety, self confidence and, above all, fun to ride.
– If you’re a road or mountain bike rider: Discover how you can increase steering precision in order to hold  your ‘line’.
– If you’re interested in novel 2-Wheeler concepts: Discover how they can still be steered with ease and fun, even when the rider is held against a backrest by seatbelts, inside a protective structure.
– Or if you’d like to know more about the contributions and limits of over 10 other known 2-Wheeler steering theories (Countersteering, Body Leaning, Gyroscopic Reactions, Front Fork Geometry, Target Fixation…).

-2- At first sight, 3-Wheeler motorcycles may seem unstable in curves, but they are not created equal and some ar better than others.
Also, 3-Wheelers will never beat narrower 2-Wheel motorcycles in European and Asian city traffic. But some 3-Wheelers can definitely offer advantages over road motorcycles in terms of safety, comfort, load carrying capacity, and yes, fun to ride.
So click on the second link above to:

– Discover an analysis of 3-Wheeler types, advantages and disadvantages.
– Discover a 3-Wheeler type presenting a strong potential in terms of comfort, safety and fun to ride enhancement over other 3-Wheelers and regular 2-Wheeler road motorcycles.
– And examine three such 3-Wheeler prototypes.

Hope you have fun exploring this non-commercial site.
