Towbar Mounted Storage:
These solutions are essential for vehicles that cannot have roof bars, or where roof mounted items present problems. Such as electric cars where the range would be reduced, or for those of us which are vertically challenged making roof access tricky.
Thule Arcos - towbar mounted storage/cargo box. Hard-shell lockable box with integrated lights (13-PIN plug).
Prices include the base platform that the box mounts onto.

Discontinued; new options in 2025 available for the Easyfold, Epos and New Easyfold models. Plus the Arcos Box.
Closest replacement is the ‘Onto 2’ box, which mounts onto the New Easyfold rack.

Thule 300 Litre storage box, mounts onto the Velospace cycle carrier which costs from £569 for the 2-bike version (view Velospace here).
The advantage of this over the Arcos is threefold: 1. The rack/box has a foot-operated tilt mechanism so you can access the boot. 2. It is collapsible making it easier to store. 3. It's a 3-4 bike rack when you don't need the box (1 bike possible with the box). The main downside is it's only 300 litres whereas the Arcos Large is 400 litres.
Hinged tow bar that swings away from the back of the van to allow rear door access, with a bike rack or box still attached. Only available for common motorhome models (e.g. Ducato, Boxer, Jumper & Movano).
