I adore these photos.
Here is my friend Khai (of KhaiCycle) with his wife Ayu and their two sons. On Bromptons.
Aren’t they adorable?
Older son Adil is on the Pere seat (formerly known as the IT Chair) with an X bar on the M-handlebar while baby Amal is on a Bobike mini with a Bryan adaptor.
I have no idea where you can get them outside of Singapore, but if you’re in town, local Brompton retailer Diginexx has both kiddie seats in stock.
