I've been looking for this for a while and it's been hard to find under $299.
Besides being a suitcase, it's also a 'Brompton Hack' : reference https://heythatsmybikeblog.wordpress.com/2017/06/19/brompton…
$239.00 alone is a great deal (I paid that amount last week ; I just didn't post the deal until I actually collected it today from the Alexandria warehouse )
With the current POPPER10 code bringing it to $215.10+ $7 $222.10 delivered , I would get another, if I didn't already have a B&W hardcase as well
wow… weight 5kgs. that's 25% of your allowance on many flights.
