HS-H023 Rear Rack Platform and Cargo Placement
Explore the HS-H023 rear rack's open tubular platform, raised end rails and side frames, and how their arrangement relates to cargo placement.
Hongsen’s HS-H023 uses an open tubular platform above the bicycle’s rear wheel. Crossmembers run between the platform’s side rails, with raised rails at both ends. Below the deck, triangular side frames connect the upper structure to the lower supports.
The open deck gives carried items a series of contact lines across the platform. That makes the item’s base relevant to placement. A base that spans several crossmembers rests differently from a small loose object that can pass between them.

Place the item across the platform's support lines
The side rails run along the length of HS-H023, while the shorter crossmembers divide the space between them. Together they form the top support area. An item placed across that area can contact several tubes, so its shape determines where it meets the rack.
For a box or bag with a defined base, compare that base with the actual deck and position it over the supporting members. A soft item can sag into an open section, so the way it sits needs attention alongside its outer size. The rack’s tubular shape gives the starting geometry; the chosen item and its securing method complete the carrying arrangement.
The raised rails mark the front and rear ends of the deck. They stand above the main contact surface, which makes the usable shape different from a flat rectangular sheet. An item’s length therefore needs to suit the space between those raised sections as well as the supporting tubes underneath.
Keep the platform position separate from the wheel space

HS-H023’s side frames sit below the platform, with angled members forming triangular outlines. The installed arrangement puts the deck above the rear tire and the lower structures alongside the wheel. The carrying surface and the wheel-clearance space occupy different parts of the same assembly.
This matters when selecting a rack for an existing bicycle layout. The item belongs on the upper support surface, while its securing parts must remain clear of the wheel. The side structure also needs room beside the bicycle’s rear frame and brake components. Match those positions with the intended bicycle before deciding the complete arrangement.
HS-H023 is an aluminium-alloy rear rack. Explore the Hongsen rear luggage rack range for related forms, or contact Hongsen to discuss the item you plan to carry and the intended bicycle.
