Tern Cargo Lid (Gen 2)

$54.99 CAD

Product Details

Rain doesn't care what's in your Storm Box, and neither does road spray kicked up from the tire in front of you. The Tern Cargo Lid (Gen 2) is the piece that finishes the job: a tarpaulin cover that snaps over the Storm Box and seals your cargo away from wet weather, prying eyes, and anything that might bounce out on a bumpy commute. Groceries, tools, a laptop bag, whatever's riding home with you stays dry and out of sight instead of exposed to the elements in an open bucket.

It attaches and releases in seconds. Rear snap buckles hold the tarpaulin taut across the top of the Storm Box for cargo runs, and when the school pickup calls for kid-carrying instead, the Cargo Lid comes off just as fast so the Storm Box can switch back to passenger mode. No tools, no fumbling with straps in the rain, just unclip and go. The tarpaulin fabric is built for repeat exposure to Canadian weather rather than a single soggy commute, so it holds up through a full riding season of freeze-thaw mornings and sudden downpours rather than degrading after the first hard rain.

At 280 x 190 x 45 mm and 0.5 kg, the Cargo Lid packs away small enough to leave in a pannier or under a seat for the days you don't need it, and it fits both Storm Box generations, so upgrading your Storm Box down the road doesn't mean replacing this cover too. It's a small, purpose-built add-on next to the cost of replacing water-damaged cargo or a soaked laptop, and it's the difference between an open cargo bucket and a genuinely weatherproof one.

Frequently Asked Questions

Find answers to the most common questions here about the Tern Cargo Lid (Gen 2).

What does the Tern Cargo Lid (Gen 2) actually do?

It's a waterproof tarpaulin cover that snaps over a Tern Storm Box to seal cargo away from rain, road spray, and view. Without it, the Storm Box is an open bucket; with it, loose items stay dry and hidden for the whole ride.

Is the Cargo Lid the same thing as the Tern Storm Shield?

No, they're two different accessories for two different jobs. The Storm Shield (Gen 2) is a canopy built to protect passengers, specifically kids riding in the Storm Box, from rain, wind, and UV, while the Cargo Lid is a flat cover built to keep cargo dry and out of sight. The Cargo Lid is not included with the Storm Shield and has to be purchased separately if you want both passenger and cargo weather protection.

Does the Tern Storm Box already come with a Cargo Lid?

No. The Storm Box ships with the Kid Lid included, which shields passengers from rain and wind, but the Cargo Lid for weatherproofing cargo specifically is sold separately. If you're buying a Storm Box mainly to haul gear rather than kids, add the Cargo Lid to actually seal it against weather.

Is this the same product as the Tern Cargo Lid Lock?

No, and the similar names trip people up. The Cargo Lid Lock is an extra-long cable lock designed to secure the Cargo Lid (and whatever's underneath it) to your bike. The Cargo Lid itself is the physical cover, this product, that the lock attaches to. Most riders who want their cargo both dry and secured end up with both.

Which Storm Box generations does the Cargo Lid fit?

It fits both the Storm Box (Gen 1) and Storm Box (Gen 2), per Tern's own compatibility listing. That means switching to a newer Storm Box later doesn't force a Cargo Lid replacement.

Is it worth adding a Cargo Lid if I already own a Storm Box?

If any of your cargo needs to stay dry, private, or contained during the ride, yes. A Storm Box alone is an open-topped bucket, so anything loose inside is exposed to rain, road spray, and view at every stoplight. The Cargo Lid is a small add-on next to the cost of replacing a soaked laptop or having cargo bounce out on a rough street, and it takes seconds to remove on days you don't need it.

Will the Cargo Lid hold up through a Canadian winter?

The tarpaulin fabric is built for repeated exposure to wet and cold rather than fair-weather use only, which matters for Ottawa-area riders dealing with slush, road salt spray, and sudden freeze-thaw rain through the shoulder seasons. Rinse off road grime and let it dry fully between rides to keep the material and snap buckles working smoothly through the winter.

How do I switch the Storm Box between carrying cargo and carrying kids?

Unclip the rear snap buckles and lift the Cargo Lid off, no tools required. The Storm Box's included Kid Lid handles passenger weather protection on its own, so once the Cargo Lid is off you're back in kid-carrying configuration in seconds, which is exactly the on/off speed Tern designed it for.
