Hope no one minds me jumping in on this, but have a similar question.
My lad is autistic and has some balance issues, he never got on with his balance bike as a nipper, so we ended up going to a little trike. He's long since outgrown that, so we've got him a 24in wheeled mountain style bike, this one

Try as we might, he just can't get the hang of it so we've had to give in and get him some stabilisers, hopefully just short term until he gets his confidence. I've bought some nice chunky ones suitable for 24in wheels, but it says they can't be fitted with QR wheels, which his bike has. How do i go about converting a QR wheel to solid axle/nut affair?
Cheers
