NO, Sir!

Let's assume you use a 2.7F capacitor @2.3V 
The charge is C*U=6.2Cb
If you discharge that at 0.2A, the time to zero is 31seconds.

For convenience, let's say the motor stops at 1.5V,
then you still have 11seconds run-time.


Two electrolytic capacitors back-to-back, will NOT explode or whatever.

To extend their useful life, you can bypass each of them by an anti-parallel diode,
to make sure that they do not see any reverse-charging current.
