These are exactly the same motors I use, with the Gecko's.
You cannot allow the Gecko drive unlimited freedom - they can (and will) pass up to 7 amps - I am sorry, I have missed what voltage you are using while I am writing this reply. I am using 24 volts. (Do not use less than 24 volts)
With the motor wired in parrallel as you have drawn it, you need to limit the Gecko to about 4 amps, by putting a resistor in the two left hand terminals - there is a list of what values to use.
Mine still get hot to touch when I am working them hard, but generally stay touchable
