NMFC Class 125 — Sports Equipment
Bicycles are low-density items that typically ship at freight class 125–150 when boxed for LTL.
Typical class: 125 · Density: 5–8 lbs/cu ft

NMFC Class 125 — packaging, handling, and freight class details
Bicycles are a classic example of a product that is moderately heavy but occupies enormous space when packaged for retail, creating a high freight class that reflects the cubic space cost rather than the product weight. Trek, Specialized, Giant, and hundreds of brands import most bicycles from Asia, with product entering through West Coast ports and distributing to retailers and direct consumers. The cycling boom of 2020–2021 pushed supply chains to their limits and exposed the fragility of global bike logistics; many brands have since diversified sourcing.
Freight class for boxed bicycles is Class 125–150. A mountain bike weighing 28 lbs in a standard 54x10x29-inch shipping carton occupies 9 cubic feet — roughly 3 lbs/cuft, Class 200+. However, NMFC bicycle classifications recognize the practical industry packaging and assign Class 125–150 for properly packaged bicycle units. This class accounts for the handling care required and the packaging materials that accompany bicycles. More aerodynamically packaged competition bikes in smaller boxes may achieve slightly better density.
Preparation for shipping a bicycle involves removing the front wheel and handlebars (both rotate 90 degrees for packing), securing the fork with a spacer, protecting the derailleur, and padding the frame at all contact points inside the carton. Improperly prepared bicycles arriving at LBS (local bike shops) or consumers with bent derailleur hangers, scratched frames, or damaged fork dropouts generate high claim rates and brand reputation issues.
The practical concern for carriers is the physical size of bicycle cartons. A carton 54 inches long and 10 inches wide is awkward to position in a trailer without creating wasted space. For truckload bicycle freight, loading efficiency improves by alternating carton orientations. LTL bike shipments require thoughtful positioning where the long carton will not have freight stacked on top of it. Rate context: bicycle freight at Class 125–150 pays above-average LTL rates. The cycling industry is a strong market for carriers who understand the fragility requirements.
