Sidekick Flat Bars

Tern Sidekick Flat Bars – Seatpost‑Mounted Passenger Handhold

The Sidekick Flat Bars give your rear passenger a stable, height‑adjustable handhold — no awkward waist grabs, just clean control and comfort. Mounted to the seatpost, they offer a secure grip through every stop, bump, and turn, making two‑up rides smoother and more confident.

Ergonomic grips add comfort, and the integrated BioLogic T‑Tool (4/5/6 mm Allen key) keeps basic adjustments within reach. Whether you’re running school drop‑off or weekend errands, these bars are a key part of the GSD’s passenger system.
