This is a 120:1 gearbox and a low power motor with speed and power comparable to an RC servo. At 6V, it has a free-run speed of 85 RPM with a stall torque of 45 oz-in. The small power requirement (3V-12V) and size make this motor great for small robot designs.
The wheels required for this Motor & Gearbox assembly are the Pololu #199 (Incoming soon).

Looks like the 7mm shafts on these aren't really the right size for a lot of wheels/tracks. Would be good to get a pointer at what is compatible.
Thanks for pointing that out to us, I'll edit the description to point to the correct wheels.
