OK Bonj, Have a quick look here

"1. Why the small wheels?
The small wheels are an essential feature of the Moulton concept. They offer many advantages.
With only
half the rotating mass of the wheels on a 'conventional' bicycle, it is possible to accelerate faster.
They are extremely stiff and much stronger than larger wheels because of the short spokes.
The aerodynamic drag is lower; there is less frontal area and less spoke area causing turbulence to slow you down.
The centre of gravity is lowered, resulting in improved stability.
The small wheels free up space normally occupied by large wheels, allowing luggage to be carried lower.
2. Aren't smaller wheels harder to pedal?
No, because:-
The gears are chosen so that they correspond to pedalling a bicycle with large wheels.
The smaller frontal area results in less aerodynamic drag.
The lower inertia means that you can accelerate faster.
If you are still doubtful,
consider the HPVs (Human Powered Vehicles) developed for the ultimate performance - many
of these use the unique 17" Moulton wheels and tyres fitted to the AM series bicycles.
3. Why the space frame?
The construction makes it far stiffer and stronger than conventional frames.
The weight is similar to that of the best conventional touring bicycles - and the Speed model is comparable with the
lightest racing frames.
In conjunction with the small wheels it results in a low centre of gravity.
The standard frame size can be ridden by cyclists of almost any size.
The low top tube leads to improved safety and controllability.
The low top tube allows it to be ridden equally easily by men and women; it is also a major advantage for elderly or
disabled riders, who cannot easily ride conventional bicycles.
4. Why suspension?
It allows the advantages of the very rigid small wheels, high pressure tyres and space frame to be enjoyed while giving
a much more comfortable ride than a conventional large-wheeled bicycle.
The
road shocks experienced on a conventional bicycle are dramatically reduced. It is a light, simple, maintenance free system.
Improved traction - the wheels do not bounce going through corners or on rough surfaces.
Reduced strain on the wheels - the wheels stay true, spoke nipples stay tight and spoke breakages are extremely rare. "
Sounds a bit better than the average 'Double Boinger' for road use
