Tern Storm Box Mini (Gen 2)

It's a weatherproof cargo box that mounts to the rear of a compatible Tern cargo e-bike, creating a protected bucket for either one child passenger or everyday cargo like groceries and gear. It holds up to 96 L and each side supports up to 20 kg (44 lb).

The Gen 2 adds zip-open side panels that work with the Clubhouse Mini Gen 2's side-opening rail. That means a child can climb in and out on their own instead of being lifted over the top, and you can reach cargo at the bottom of the box without unloading everything above it. If Scooteretti has both generations in stock, the original Storm Box Mini remains a solid, lower-cost option; the Gen 2 is the pick if the side-access feature matters to how you use the bike day to day.

It fits the GSD (Gen 1, 2, and 3), HSD (Gen 1, 2, and 3), Quick Haul, Quick Haul Long, and Short Haul. It requires either a Clubhouse Mini Gen 1 or Gen 2 for installation; if you're using the Clubhouse Mini Gen 2, it needs the Flat Bar or Child Seat Expansion Bar installed first.

Yes, it's built from tarpaulin and ripstop nylon, the same weather-resistant materials used across Tern's Storm Box lineup, and the included Kid Lid Mini adds a further layer of wind and rain protection for a child passenger. For maximum weather protection, especially through an Ottawa winter, it can be paired with the Storm Shield Mini to form the full Clubhouse Fort Mini enclosure.

For hauling a child passenger or an irregular cargo load, a bucket-style box is a smaller investment than the cost and hassle of strapping and re-strapping bags every trip, and it protects both passenger and cargo from weather that an open rack or basket doesn't. If you're only ever hauling a couple of small bags, a simpler rack or pannier may be enough; the Storm Box Mini earns its keep once kids, groceries, or bulky gear enter the picture.

The full set weighs 2.16 kg (4.8 lb), light enough that it doesn't meaningfully change how the bike handles, which matters most when you're already carrying a passenger or a full cargo load.

Yes. Scooteretti carries it online with free shipping across Canada on orders over $99, and it's available to see in person at the Ottawa Experience Centre, where the team can confirm compatibility with your specific Tern model before you buy.
