Product Details
The Tern Storm Box (Gen 1) is the original weatherproof cargo bucket built for Tern's GSD Gen 2, and it's the accessory that first proved a cargo e-bike could handle both school-run passengers and a full grocery haul in the same enclosed box. Paired with the Tern Clubhouse+ and Tern Sidekick Wide Decks, it transforms the rear of the GSD into a fully enclosed, weather-protected compartment.
Two weather-resistant lids handle two different jobs. The Kid Lid cinches tight to keep young passengers warm and dry through wind, rain, or snow, while the water-resistant Cargo Lid, included with this generation, seals the box to protect groceries, gear, or deliveries from both the weather and prying eyes. Together they carry two young kids, in or out of compatible child seats, or up to 160 L of cargo.
It's built to work with both the Clubhouse+ Flatbar and the Child Seat Expansion Bar, and it catches the small stuff too: mittens, sippy cups, and teddy bears that would otherwise slide off the bike mid-ride. Riders wanting extra weather protection can add the Storm Shield on top, though the Storm Box on its own already handles most Canadian rain and snow.
This is the original Storm Box generation, since replaced by the Tern Storm Box (Gen 2). It requires the Clubhouse+ and Sidekick Wide Decks already installed on a GSD Gen 2 and is part of the four-piece Clubhouse Fort weather protection system. Remaining stock is limited, since Tern has moved production to the newer generation.
