Compatible with several storage box options: the hard-shell ‘Santu’ box and the collapsible ‘Onto 2’ box (the latter is similar to the backup box that used to fit onto the VeloSpace carriers). You can even take a box and one bike, but that requires the 3-bike version with the 4th bike adapter and an additional ‘arm’ to hold the bike to the A-Frame (the latter is required because there would be no other bikes to clip onto as you would normally do with the extra bike adapter).
Optional accessories available include:
A neat cable lock (£65), to reduce faff-time - useful when your hands are too cold to fiddle with keys and locks.
Folding Loading Ramp (£59)
