It's roomy inside and its shape is maintained by a steel frame.
It's big enough to accommodate one Wii set complete with a Wii Fit Balance Board, Power Up Charge Stand, Wii remotes, Nunchucks and a few games.
The frame at the back has a bracket that slides into the front carrier block.
You can even use the folding basket with the bike as a shopping cart when you go to the supermarket.
There are other front luggage options. There is the S Bag that fits on S-type Bromptons. Then there's the C Bag which doubles as a messenger bag. The T Bag which is Brompton's touring bag is their roomiest. The O Bag is waterproof. Last, they have the A Bag, which is a leather attache case. Buyer beware, though, these bags are pretty expensive.
I dream of owning an A Bag one day, because it looks sharp and classy. Bagay na bagay for commuting to the office. But I still have to save up for it.
For now, I'm happy with my Brompton Folding Basket.
Happy Riding, everyone!!!
