Finding suitable motors

can anyone here give me idea on which motor i should use for my project?
my porject is on Light-Guided vehicle and it requires 2 motor on the back wheels and a multidirectional wheel at the front.

i am using 2 DC motors at the back wheel.
Preferably wheels that are connected to the shaft.

can anyone here has the part number of the motor?

thank you

If you want to join the wheel straight to the shaft, you are after a motor and gearbox combined job. The gear ratio will determine the maximum speed and torque. Have a look at these:
