We took our soon-to-be 3 year old on a bike ride - in a carrier at the back of my (mom's) bike. He complained of being dizzy mid-way so we told him to look up - at my hat or just around so that he wouldn't get dizzy. This seemed to help for the remainder of the trip, but now, even several months later, he won't get back on the bike as he doesn't want to get dizzy again.

So, I am wondering whether anyone else has experienced this and/or whether anyone can think of a good solution for this. I was thinking of a product which would block his vision of the road below - even a makeshift/homemade one. All suggestions welcome.
