Whether you're transporting a cooler of refreshments, a toolbox full of essentials, or your little grand champions, Tern's Sidekick Wide Decks are your optimal solution. Specially crafted to extend the GSD's integrated lower decks to a wider 12 cm, these add-ons provide both increased foot comfort for passengers and additional peace of mind for riders.

Each Sidekick Wide Deck is robust enough to hold up to 35 kg — that's a total support of 70 kg for both Decks. They are an excellent choice for cargo-stowing, keeping your load low to the ground for improved handling and stability. With the Sidekick Wide Decks, carrying heavy, uneven cargo becomes something you can handle with ease.
