I have buy many small motor like this one on a small shop around my house :

robotshop.com/en/solarbotics … tor-2.html

But the same shop dosen’t sell anything that i can transfert it to something else like pulley. They have some gears that don’t fit with the different shaft of their small motor. Since gear require more precision in fixing motor close to the thing that you want to make rotate, i prefer pulley for now.

Did those pulley will fit on those motor?

Do you have some information regarding wich pulley fit on what dimension of shaft somewhere?

Thanks.

Normally you would not consider adding a pulley directly to the output shaft of a motor, since the motor would rotate too quickly and likely with very little torque.
You should add a gear down. If budget is important, consider the Tamiya series which has inexpensive gear motors, as well as pulleys which are compatible:
