Banebot Motor/Clutches?

sup guys, i need some help. Im on the verge of getting a Banebot geared motor for a two wheel project that im working on. robotshop.ca/rbban31-banebots-spur-gearmotor.html

My question is : is anyone familiar with this geared motor? can it spin freely by hand if theres no voltage applied to it?

I know with the gearbox/motor arrangements that i work with its almost impossible to turn a gearbox by hand.

Any good sources out there for small (12vdc) electromechanical clutches?

What i want to be able to do is mobilize this bot with two dc motors at the wheel with the option to override the motor and push it by hand w/o damaging parts.

worse case id have to design a way to engage and disengage the motor with some mechanical arrangement

feedback greatly appreciated.
Thank you in advance

The Banebots 12V 263RPM 2527oz-in Planetary Gearmotor w/RS-540 Motor shaft does not turn by hand, though it is possible if you add a large wheel that it will rotate - the gearing is planetary so it is not inherently locking. Unfortunately we don’t yet offer electromechanical slutches.
