Without actually trying one you can't be certain but they all seem fairly standard so they should be OK.
I would suggest the 6V 300 rpm ones would be the best for Antweights.

I recently found these on ebay.

If you take the tube and switch off you and up with a 3 gm motor gear unit for £1.25.

Just had a quick test and I had difficulty in stopping the output gear with my fingers when running on 7.4 V.
I am hoping to squeeze a couple into a nano at some stage.

Any chance you know the MOD of that gear on the end?

I am afraid not it is coarser than the standard white gears I use which I think are mod 0.5.

The Ebay listing says the output gear is 4.5mm dia, 6 teeth, 0.6 mould [sic]

Oops :oops: my wife is always telling me to read the instructions I have just been designing a wheel that fits onto the gear as the speed seems about right.

I used motors similar to these on one of my Nanos (Nudge) and they're nice but I found them painfully slow. According to the specs though these may actually be geared faster, in which case they could be quite useable.

Not quite as fast as the add I just measured one at 220 rpm on 7.4v but motor wheel and tyre have come out at 4.2 gms.

Just got a simple pusher up and running perhaps walking would be a better description as it is very slow.
The combination of the motors being only half the advertised speed and the small wheels means I shouldn't be driving out of the arena so often.
At least the lack of breaking on these controllers is not a problem.
