Welcome to China Riders!
This attaches to any standard trailer hitch. Some minivans have trailer hitches. It's easier to secure a motorcycle to this carrier than to strap it down inside a minivan.

My daughter is 13. I bought her a 2021 CSC TT250 for Christmas. It is way too much bike for her right now, but I got it for a fantastic price. She's tall at 5' 4" but doesn't have the upper body strength to manage it right now. It weighs a bit over 300 lbs. In the next couple of years, she will grow into it. I explained that her foray into the world of dual sports will be in stages and take time. She's totally cool with that.
