Heads up!

This article mentions third-party child seats that are not manufactured by Tern. Please note that child seat designs might change, and that their manufacturers may choose to maintain the same product name even after the design has changed.

For your safety, always consult with your bike dealer, or with the child seat manufacturer or reseller, to make sure you have the right seats to safely carry your kid(s).

We’ve made no secret of the fact that we envision Tern bikes as real car replacements. You don’t leave your car in the garage on rainy days, and the same should be true of your bike.

We heard from many GSD owners that the only thing stopping them from carrying their families every day was wet weather. So, we created the Clubhouse Fort to keep little passengers dry and cozy on the GSD.

The ensuing flood of pictures of smiling Clubhouse Fort passengers gave extra urgency to our next project: creating a similar (but smaller) weather protection system for our more compact cargo bikes that only carry one kid, like the HSD, Quick Haul, and Short Haul.

What is the Clubhouse Fort Mini?

The Clubhouse Fort Mini is a combination of three accessories that turns the back of your bike into a weather-protected compartment for a child passenger.

It's designed to fit one kid, seated either in a child seat or using the Clubhouse Seat Pad plus Clubhouse Backrest combo. The recommended maximum passenger height is 140 cm (4’7”), plus a helmet.

From your perspective, it keeps your child dry, cozy, and content in all kinds of weather. From your kid's perspective, it’s a comfy cockpit, a seat of honor, and maybe even a magical play space that makes riding that much more enticing.

Here’s what it looks like:

Which bikes does the Clubhouse Fort Mini fit on?

As we mentioned in the previous section, the Clubhouse Mini was designed for our more compact cargo bikes that only carry one kid, including the HSD, Quick Haul, and Short Haul. However, it also fits on the GSD as a one-kid alternative to the full-size Clubhouse Fort.

Key elements of the Clubhouse Fort Mini mount to the bike using a Tern-standard rear rack system called the Upper Deck System. So, the Clubhouse Fort Mini may work with future bikes that also feature the Upper Deck System.

Which accessories make up the Clubhouse Fort Mini?

Three accessories make up the Clubhouse Fort Mini. Each accessory is sold separately. Seating (such as a child seat or passenger cushion) is required and will vary according to the passenger.


Is riding with a big black box on the rear of my bike safe?

We added plenty of reflective strips to the Storm Box Mini and the Storm Shield Mini to boost visibility. Both accessories also include rear loops for attaching safety lights to make nighttime riding safer.

Of course, you know your area and riding conditions best, so exercise judgment and caution when using the Clubhouse Fort Mini.

How to Build the Clubhouse Fort Mini

1. Install the Clubhouse Mini

The Clubhouse Mini forms the frame of the Clubhouse Fort Mini. It’s required to install both the Storm Box Mini and the Storm Shield Mini.

2. Install the Storm Box Mini

The Storm Box Mini is a big, soft-but-sturdy box that helps protect your child from the elements. The Storm Box Mini was designed with kid-carrying in mind, as you can see from the following features:

  • Includes a water-resistant Kid Lid Mini that cinches tight around a little passenger, sort of like the spray skirt of a kayak
  • Supported by two built-in bottom plates that serve as foot support for a big kid
  • Handy opening in the back for easy access to a Yepp Maxi or Nexxt Maxi child seat’s knob
  • Inner pockets for holding snacks, toys, and other gear
  • Incredibly effective at catching all the toys, clothes, and other items that may fall from little hands while riding

But the Storm Box Mini also serves another purpose: when you’re not carrying a kid, you can toss in up to 100 L of cargo.

3. Install your seating of choice

You’ll need to install passenger seating inside the Clubhouse Mini. Options include:

4. Install the Storm Shield Mini

The Storm Shield Mini is a weather-resistant canopy that protects your kid from harsh weather conditions like rain, cold wind, and even extreme sun.

The is made from waterproof nylon that keeps your passenger dry on wet days. We added a rear ventilation panel for airflow to prevent the passenger cabin from getting too stuffy. See-through inserts in the side panels let your kid enjoy the view, while the Storm Shield Mini’s fiberglass tent pole structure is designed to hold its shape, even on windier days.

So what do you do with the Storm Shield Mini on sunny days? Well, you’ve got two choices. The first is to roll up the side panels and use the Storm Shield Mini for UV protection. The second is to remove the Storm Shield Mini and store it until the next time you need it—it folds down flat to make this easier.
