Modded a MUJI pet carrier so my cat can ride shotgun on my Brompton

I wanted a way to take my cat on bike rides, so I did a simple mod using a MUJI Boston pet carrier.
To make it work, I just added an aluminum plate to the bottom of the bag for structural support (with some 3M VHB Dual lock reclosable fasteners), and then bolted a Brompton bag adapter directly through it. I chose to mount the bag longitudinally (front-to-back) rather than sideways. I did it this way because it's more comfortable for the cat to sit in, and she can just lift her head to see straight ahead.
Just a heads up, it seems like this specific MUJI pet carrier is only available in Mainland China.

Here is the link to the bag if anyone wants to take a look:
