Tern HSD Cache Box

Hidden “Glove Compartment” for Your HSD The Tern HSD Cache Box adds a discreet storage spot right under the seatstay, so tools, tubes, and a chain lock live on the bike instead of in your pockets or panniers. It is designed to blend into the HSD frame, giving you just enough always-there space for the essentials you need on daily rides and errands. Bolted directly to the frame with a stiff, water-resistant shell, it will not sway, sag, or tempt grab-and-go theft the way a hanging bag might. Open it up, grab what you need, close it, and ride away with a clean cockpit and less clutter. Compact. Clever. Essential. Low-profile design that tucks under the HSD seatstay and visually disappears into the frame. Perfect for carrying a chain to pair with the HSD’s frame lock, plus tubes, levers, or a mini pump. Stiff, frame-bolted construction prevents swinging while you ride and helps deter opportunistic theft. Water-resistant outer fabric and EVA shell help keep grit and spray off your gear. Inner mesh pocket keeps smaller items organized and easy to find. Keeps tools and locks off the handlebar and out of your main bags for a tidier, quieter setup.
