Andersen Unus Shopper — Hydro 3.0 Bag

Some shopping trolleys look like medical equipment. The Unus Shopper is not one of them. It's Andersen's design-award-winning urban shopper — four design awards including the Red Dot and Universal Design Award — paired here with the Hydro 3.0. The aluminium frame, height-adjustable 3-way handle and 17 cm ball-bearing wheels make it as practical as it looks. Bike n Easy compatible with the Type 2 Adaptor.

Compatibility

The Unus suits urban shopping, design-conscious daily use, and households where people of different heights share the trolley. The 17 cm wheels handle smooth pavement and most kerbs comfortably but aren't designed for serious off-road or gravel use — the Tura or Royal are the heavy-terrain options. Bike towing works via Andersen's Bike n Easy Type 2 Adaptor.

Attaching to a bicycle

This Shopper is compatible with Andersen's Bike n Easy attachment system, which lets you switch between pulling on foot and towing behind a bicycle in a few seconds.

Two components are needed: an adaptor on the Shopper (this frame takes the Type 2 Adaptor) and a coupling unit on the bicycle. The bike-side coupling depends on your bicycle's geometry:

Pull Easy — bikes with a rear luggage carrier
Easy Snap — alternative for rear-carrier bikes
Big Easy — bikes without a rear rack (mounts to seat strut)

The full breakdown with fitting guides and videos is on the Andersen Bike n Easy attachment guide.

Fitting & installation

The Andersen frame arrives fully assembled. The bag clicks onto the frame using the HängFix system (on Royal, Royal Plus, and Unus frames) or attaches via integrated straps (on Scala, Komfort, and Tura). Both are tool-free.

For bicycle attachment, see Compatibility above and the Andersen Bike n Easy guide for the full fitting walk-through, including PDFs and video tutorials per coupling. The Unus Shopper user manual is available to download on this page.

FAQs

Can the Hydro 3.0 actually be worn as a backpack?

Yes — the carry straps stow inside a flap on the back of the bag during trolley use, and pull out for backpack mode when you need to take just the bag (into a shop, onto a bus, up flats of stairs). It's not as comfortable as a dedicated rucksack for long distances but works for the "last quarter mile" off the trolley.

How does the thermal compartment work alongside the waterproof outer?

The thermal compartment is a separate insulated section inside the main waterproof outer shell — so chilled items stay cool AND dry even in heavy rain. The trade-off is the thermal section eats into the 62L main capacity: effective ambient-storage volume is around 54L when the thermal is in use.

Why does the Unus cost more than the Scala if both are pull-alongs?

Three reasons — the aluminium frame (lighter and stiffer than the Scala's), the height-adjustable 3-way handle (Scala has a fixed flat handle), and the 17 cm ball-bearing wheels (versus the Scala's 15 cm). It's a design product, so some of the premium is also for the form factor that won the Red Dot.

Will the Unus handle gravel paths or unpaved tracks?

It'll handle them but it's not what it's optimised for. The 17 cm wheels transmit more vibration on rough ground than the Tura's 29 cm pneumatic wheels or the Royal's larger options. For regular off-road use, choose Tura or Royal. For occasional gravel, the Unus copes fine.

Hitch A Bike Expert Note

The Hydro 3.0 is the bag we'd recommend for any UK customer who shops year-round and wants one bag that handles everything. Two things to know: the roll-top closure means you lose 3-4 litres of stated volume per fold when sealed for full waterproofing — pack accordingly. And the wide roll-top opening isn't ideal for tall items like baguettes or wine bottles standing upright; those work better in the Holk or Famke. The backpack mode is genuinely useful — most owners discover it after a few months and wonder how they shopped without it.
