on / off, no tools
Fits your Brompton C Line
Fits C Line with folding unaffected after the seat is removed.
Verified fitment · 2017-2026 · 16 inchDesigned around the fold, not against it
Every other child seat treats a folding bike like a small bike. We treated the fold as the spec.
10-second quick release
Set the clamp once. After that the seat clicks on and off in seconds.
Folds with the seat on
The fold sequence is unchanged; the package grows 9 cm.
T Line & G Line ready
Our stem mount never clamps the seatpost, so carbon posts are safe.
One flagship seat. Accessories that earn their place.
A small catalog is a feature: everything here is tested through 500 fold cycles before it gets a SKU.
