What is the Clubhouse Fort?
The Clubhouse Fort is a multi-part, weatherproof passenger compartment designed to fit up to two kids (including age-appropriate seating), with a maximum recommended height of 140 cm plus a bit of extra space for a helmet.
The Clubhouse Fort keeps kids dry, cozy, and content in all kinds of weather. It can be a comfy cockpit, a seat of honor, and maybe even a magical play space that makes biking feel like an adventure for your kids. A clubhouse on wheels, if you will. This is what the setup looks like:
What are the Clubhouse Fort accessories?
The Clubhouse Fort is built with four accessories that are sold separately. Here they are:
1. Clubhouse
The Clubhouse forms the foundation of the Clubhouse Fort and is required to install its top and bottom sections. It has room for up to two compatible child seats and can also be fitted with Clubhouse Seat Pads and Clubhouse Backrest, making it easy to bring your little co-pilots along for the ride.

Depending on your Tern bike, the Stow Decks or Sidekick Wide Decks form the essential base of the Clubhouse Fort and provide foot support.
3. Storm Box
The Storm Box is a massive, durable yet flexible container that helps keep kids safe from nasty weather. It comes with a water-resistant Kid Lid that fits snugly around little riders, which is a bit like a kayak's spray skirt.
Designed with kid-carrying in mind, the Storm Box is also effective at catching all the toys, clothes, and other items that may fall from little hands while riding—just scoop your kids' missing mittens out of the bottom of the Storm Box.
But the Storm Box isn't just for transporting your kids. When you're not carrying them, you can load the Storm Box up with a whopping 156 L of cargo. Add the Cargo Lid (sold separately) to turn it into a fully enclosed, weatherproof trunk for your shopping hauls.
4. Storm Shield or Sun Shield & Rain Shield
The Clubhouse Fort has two roof options: The Storm Shield and the Sun Shield & Rain Shield.
Storm Shield
The Storm Shield is like a cozy bubble for your little passengers that keeps them dry in the rain, protected from chilly winds, and shaded from the harsh sun. Made from waterproof nylon, it shrugs off the rain while a rear ventilation panel keeps fresh air flowing. Big, clear side panels mean kids can still enjoy the view, and the sturdy fiberglass tent pole structure holds its shape, even when the wind picks up.
Designed to stay on the bike through every season, Storm Shield is a practical, all-in-one solution for families who want dependable coverage while carrying kids year-round.
Sun Shield & Rain Shield

The Sun Shield is a lightweight, breathable bicycle sun canopy offering UPF 50-rated protection to keep kids safe from harmful UV rays. It’s designed with side panels that roll up to allow maximum air flow and easy access to the passenger cabin, plus a mesh front that lets you keep an eye on all the fun happening inside. When not in use, the Sun Shield easily folds down into a small bundle for compact storage.
The Rain Shield is a waterproof bike cover add-on that easily secures over the Sun Shield via snap buttons, transforming the bike sun shade into an all-weather canopy to keep kids dry and comfy year-round. With a 12,000 mm waterproof rating, it handles everything from drizzles to heavy downpours. The large roll-up windows allow ventilation and easy access to the passenger seats. When the weather clears, simply fold the Rain Shield up and stash in your pannier.
The Sun Shield and Rain Shield are sold separately, giving riders more flexibility. They’re a good choice for families who don’t want full-time weather coverage or prefer separate protection for sun and rain.

Should I get the Clubhouse Fort?
If you live in an area with unpredictable weather or need a reliable setup for year-round family biking, the Clubhouse Fort is a smart choice.
It provides a secure, season-proof space for up to two kids, keeping them dry on rainy days and shaded from the sun. With two roof options—the all-in-one Storm Shield or the modular Sun Shield & Rain Shield—you can tailor the setup to your climate and needs.
