Nice Gearmotors & Wheels!
Eureka! I finally stumbled across the 120:1 gearmotor & wheel combo I've been asking for these past years. Every other wheel/gearmotor I've found uses a 1:48 ratio: too fast with no torque. This one is vastly superior and actually usable for robotics. I'll make a simple diff-drive bot with them. Might be good for a lightweight 4WD rover too. Both motors demoed at 3 volts in video below. Gearmotors look identical from the outside. Can't tell from the item description, no mention of the gear ratio. Hopefully US seller cenn2010 has plenty more just like these. $7.29 OBO for the deuce w/free ship. He didn't take any of my lowball offers, but he might go $7 if you tell him erco sent you.
