Can children ride a bike if you buy "Discover University"?

Those bikes are way to big for kid age. So i would say no seeing those were the only bikes they showed.

I also did not spot any kids in the University towns so my guess none will be in those towns or I would think we might have spied one or two somewhere.

But in both aspects who knows - perhaps both ideas is a yes and the devs chose not to show us - to keep it a secret. Hopefully you find out on the 8th.
