For the Mechano-hog/Chopper you just need the riding skill (150) or level 40, to use it, and then pay an engineer a lot of money/mats to make it for you.
For the flying mounts that engineers can make, you need to not only have the artisan riding skill (300) which costs 5000g (4000g at exhalted reputation with any major faction), to use them. But you also must be an engineer of engineering level 375 to make and lvl 70 to use it. The recipes should be available at the engineering trainers in Shadowmoon Valley.
