Passenger System Sidekick Flat Bars Gen 3 · Passenger Grab Bars · Seatpost Mount · 30.9–34.9 mm · Adjustable · Orox / GSD / HSD / Quick Haul / Short Haul Tern Sidekick Flat Bars Gen 3 Seatpost-mounted grab bars for rear cargo bike passengers — adjustable height and angle, ergonomic grips, and a built-in 4/5/6 mm Allen key. Part of the Tern Passenger System; works with the Captain's Chair and Sidekick Seat Pad. $125 CAD · set of two Part of the Tern Passenger System — consult the Passenger Guide before use. The Sidekick Flat Bars require a compatible seatpost diameter of 30.9–34.9 mm. A low saddle height may leave insufficient exposed seatpost for proper mounting — consult Tern's seatpost-mounted handhold selection guide if saddle height is a concern. Recommended for passengers 130 cm (4'3") or taller who can sit unaided. Carrying passengers safely requires additional accessories beyond the grab bars alone. Seatpost 30.9–34.9 mm diameter Adjustable height and angle 130 cm passenger minimum (4'3") The Tern Sidekick Flat Bars Gen 3 give rear-seat cargo bike passengers a secure, fixed grip point — a necessity on a moving cargo bike where a passenger has nothing else to hold on to. They clamp to the seatpost and adjust in both height and angle so the grip position can be dialled to the passenger's reach and comfort. Ergonomic grips reduce hand fatigue on longer rides. A 4/5/6 mm Allen key is integrated into the bar — common bolt sizes for adjusting the bars themselves or other accessories without carrying a separate tool. The bars fit seatposts from 30.9 to 34.9 mm, covering the range used across the Orox, GSD, HSD, Quick Haul, and Short Haul. Compatible with both the Captain's Chair Gen 2 and the Sidekick Seat Pad for a complete passenger seating setup. Highlights Seatpost mount — adjustable height and angle The bars clamp directly to the seatpost rather than attaching to the rack or frame. Height adjustment positions the grips at the right reach for the passenger's arm length and the seating height — a child sitting on a Sidekick Seat Pad at a different height than an adult needs different bar placement. Angle adjustment lets the grips tilt forward or back for natural wrist position. Both adjustments are made with the included Allen key or the bike's own hex bolts. Integrated 4/5/6 mm Allen key — tool in the bar A multi-size Allen key (4, 5, and 6 mm) is built into the bar itself. The 4/5/6 mm range covers the most common bolt sizes on Tern cargo bike accessories — adjusting the flat bars, tightening seat mounts, and most rack hardware all fall in this range. The tool doesn't need to be carried separately and doesn't get lost. A small but genuinely useful detail on a bike that gets loaded and adjusted regularly. 30.9–34.9 mm seatpost range — fits five bike models The clamp accommodates seatpost diameters from 30.9 to 34.9 mm — the range that covers the Orox, GSD, HSD, Quick Haul, and Short Haul. Confirm your specific bike's seatpost diameter before ordering. Also check that the saddle height leaves enough exposed seatpost for the bars to clamp at a usable height — if the saddle is very low, there may not be enough seatpost length above the frame to mount the bars correctly. Works with Captain's Chair and Sidekick Seat Pad The Flat Bars are recommended alongside the Captain's Chair Gen 2 or the Sidekick Seat Pad — Tern's two main rear passenger seat options. The seat provides the sitting surface; the bars provide the grip. Neither the seat nor the bars alone is a complete passenger setup — both are required, along with other Passenger System accessories as specified in the Tern Passenger Guide. 130 cm passenger minimum — who can use these Tern recommends the Sidekick Flat Bars for passengers 130 cm (4'3") or taller who can sit unaided without support. This lower threshold than the Sidekick Seat Pad (140 cm) reflects that grab bars are usable by slightly younger or shorter passengers — but the passenger must still be able to maintain their own seated position independently. The bars provide a grip point, not structural passenger support.
