There has to be a better way to keep the tires on Wheeleez carts

I lost my factory Wheeleeze pin on a walk to the coast, so I upgraded to a couple of these in the "Mini SIze" category. THe ones not rated for climbing are the smallest.

I like that idea HFF.  They'd have to be really small to fit through that small hole.

I put mine together wrong, so I cant take my wheels off! 

I use zip ties for it and cut it off when I need to , never comes off!

get 2 small padlocks that will fit threw the hole

Go to an ACE hardware and replace them with the same style of pin.... except the ones from ACE have a stronger snap back on the ring. I haven't lost another one after that day.

+1 to this, the ones from a hardware store have a much stronger spring.

If you are out and about and have lost a pin, a stick works in a pinch but will need frequent checking on a long pull.

+2.  I recently lost one of my cotter pins so I replaced it with one from a hardware store in Fort Bragg and its definitely harder to pop it off.  I'd recommend switching out these if you don't want to deal with the nonsense of the stock cotter pins.

I have the smaller Hobie/wheeleze cart which had grooves in the axle but no holes for the pins.

+1 to what Yakfisherman shows above. Just gotta drill two small holes thru the axle shaft

Actually the nice part was I didn't have to do any drilling in mine.  I just used the existing holes that the original factory pin used to be in before it fell out.
