My husband bought Brompton bicycle recently
and asked me to make a front bag for it.
This is the e.g. of the Brompton front bag.
And this is the accessory which will hold the bag onto the bicycle.
I have made the slide in pouch at the back of the bag.
This is the pocket for knickknacks.
The slide in pouch is secured by the two velcro strips.
The size is about W 45, H 35, D 14cm
It has a bottle holder on both sides.
I'll make a flap with this red strap today.
