Tern Cache Box L

The Cache Box L is the lockable frame bag built specifically for the Tern Quick Haul Long — a 5 litre, integrated storage compartment that sits below the battery and looks as if it belongs there. Big enough for a chain lock, a multi-tool, rain gear or a small first aid kit, but discreet enough that you would not necessarily spot it.

The standout feature is the built-in 3-digit combination lock. That makes it useful for parking the bike at a cafe or outside the shops without worrying about anyone helping themselves to whatever you have stashed inside — a small but genuinely useful piece of security on a bike that is often left briefly unattended. There is also an inner pocket designed to hold a tracking device, adding a quiet extra layer of theft deterrent.

Inside, detachable dividers and an inner mesh pocket keep everything organised — the kind of detail that matters when you are reaching in for one specific thing rather than emptying the whole bag onto the pavement. Built from EVA for water resistance and durability.

For the HSD, the smaller, non-lockable Cache Box is the equivalent product — same idea, smaller scale, designed for the HSD’s frame geometry.
