Tern Cargo Hold 37 Panniers Gen 3
A pair of 37-litre panniers in Bluesign-certified 1000D nylon — Fidlock magnetic buckles, three conversion modes (Bucket, Rolltop, FlatFold), internal organiser pockets, and waterproof construction. Requires Pannier Adapter Gen 2.
The Tern Cargo Hold 37 Gen 3 are a pair of 37-litre panniers built for daily cargo use on Tern cargo bikes. Three conversion modes address different loading situations: Rolltop seals the bag against weather with the rolled-and-buckled closure; Bucket Mode opens the top wide for easy drop-in loading of bulky items; FlatFold collapses the empty bag flat for storage when not in use. Fidlock magnetic buckles close the rolltop one-handed — the magnetic guidance makes alignment fast without looking. Internal pockets accommodate chain locks, cables, and smaller items separately from the main cargo. Bluesign-certified 1000D nylon and waterproof construction match the Cargo Hold 28 in durability and weather protection at a larger volume and paired pricing. A Pannier Adapter Gen 2 is required for mounting — it is not included.
Highlights
Three modes — Bucket, Rolltop, FlatFold
Rolltop Mode: roll the top down several times, click the Fidlock buckle, and the bag is weather-sealed. Bucket Mode: open the top fully and fold it back for a wide-open rectangular container — drop in grocery bags, a jacket, or anything too bulky to feed through the rolltop. FlatFold Mode: when empty, the bag folds flat for compact storage against the bike or in a bag. The three modes are the primary advantage of the Gen 3 design over more basic panniers that only offer one closure configuration.
Pannier Adapter Gen 2 — required, sold separately
The Cargo Hold 37 Gen 3 does not use conventional K-style pannier hooks. It mounts via the Pannier Adapter Gen 2 — a specific interface piece that must be installed on the bike's rear rack first. This requirement exists because the Cargo Hold's mounting system is integrated with the adapter's quick-release mechanism rather than using generic hooks. Buying the panniers without the adapter means they cannot be mounted. Confirm adapter availability and compatibility for your specific bike before ordering.
Fidlock magnetic buckle — one-handed rolltop closure
Fidlock's magnetic buckle system guides the two halves together when brought within range — they snap shut without precise alignment. Closing the rolled top one-handed while the other hand manages cargo, a lock, or the bike itself is practical rather than just a marketing point. The buckle releases with a deliberate pull and resists accidental opening under load or vibration.
Internal pockets — chain locks and small items
Internal organisation pockets keep a chain lock, U-lock, cables, or accessories separate from the main cargo compartment. A chain lock loose in a 37-litre bag is awkward to retrieve and can damage softer items — a dedicated internal pocket keeps it accessible and separated. The pocket is sized for common lock formats used with cargo bikes rather than being a generic small-items pocket.
74 L combined — full grocery run capacity
Two Cargo Hold 37s give 74 litres of total pannier volume — enough for a full weekly grocery shop without overflow onto a rear rack platform. A standard shopping cart holds roughly 120–150 litres; 74 litres represents a meaningful portion of a weekly load across both panniers. The 5.4 kg per pannier load limit (12 lb) is the binding constraint — 37 litres loaded with dense items like canned goods will hit the weight limit before filling the volume.
Child seat compatible — panniers alongside passengers
The Cargo Hold 37s are compatible alongside child seats from multiple brands on compatible Tern cargo bikes. The pannier positioning is designed to coexist with rear-mounted child seats — both can be on the bike simultaneously without the panniers needing to come off for passenger use. Confirm compatibility for your specific bike, child seat, and adapter combination via Tern's compatibility checker.
