I write these notes because I have modified ADY.

After five years ADY was in need of an update and I put into practice the ideas that were born in this time.
Preserving of "ADY" what was already very good I redid the chassis, the steering mechanism, the chain route, I added a disc brake at the rear and I also shortened her by 20 cm.
The result is a "SUV" able to do the rough terrain, to carry a large load to be convenient and handy, but unfortunately it is quite heavy.

I am not responsible for problems deriving by realizations built folowing my drawings.


If you have not already seen how I built ADY give it a look , there are also valid informations for ADY-2.
First of all I have changed the transmission system removing the ADY's third shifter that was needed to have a wide velocity range .
Changing a wheel hub of a 24 " wheel I can use 9-speed sprockets (11/ 34). I then used three crowns on the pedals ( 22-32-44 ) which guarantee a very short climb ratio and a good top speed . The use of only two return gears ensures smoothness and allows to have a distance from the ground of the chain very wide.
The chassis has been completely redone , shorter to improve traction . The seat is moved back to the have maximum charge on the drive wheel even if it leads to a little worse  cornering stability.  The lower wheelbase allows to reduce the turning radius . The seat is a bit ' high off the ground and, even if it limit the cornering speed, is needed to improve the off-road capabilities , you can go from very high sidewalks and overcome substantial barriers .
The unusual configuration of the frame based on a lower triangle and a seat that integrates it on the top is very robust . The rear wheel support made ​​from two parallel tubes do not interfere at all with the chain.
The steering linkage was revised by increasing the lever arms to eliminate the hardening steering that has happened on ADY .
The rear disc brake has proven to be very useful, maintains the directionality to slow down and is more comfortable than the front discs , which have a fantastic ability to block . The parking brake that is controlled by a lever brake is indispensable.
The integrated roof rack is very sturdy and planned for the seat of the granddaughters .
The front end , wheels and spindles are those of ADY recovered and reconditioned.
Now I have added an electric motor ADY-2 Motor and a dual-tone horn.
