Polaris’s Cargo bag doesn’t have a massive volume, but it makes up for this with plenty of decent features. The semi-rigid base has plastic runners along the bottom to help it slide up kerbs and steps, while two rear wheels help when you’re pulling it along. Removable wheelbags are a nice touch, and are well constructed too.
Inside there are a number of pockets, which provide space to store bits and pieces such as quick-release skewers and pedals. The internal volume is smaller than some other bags offer, which may mean having to remove or lower your bike’s seatpost, but all we had to do to fit a bike inside was twist the handlebar in the stem.
