Tern Sidekick Wide Decks – Rear Deck Extensions for GSD Gen 2

The Sidekick Wide Decks expand your GSD’s rear platform, giving passengers more foot space and cargo more stability. Designed to keep weight low and centred, they improve handling when carrying kids, heavy loads, or oversized panniers.

Each deck supports up to 35 kg and features slotted openings for easy strapping of toolboxes, coolers, or awkward cargo. The left deck includes a cutout for thru‑axle access, making maintenance easier without full disassembly.
