bike rack trailer

Capacities vary by style: single-bike pull trailers are built for one bike (typically for towing children or cargo), hitch-mounted platform racks commonly carry two bikes, and trunk-style racks typically carry two to three bikes depending on the model.

Trailer-style child or pet carriers typically attach to a bicycle via a universal or quick-release coupler. Vehicle-mounted racks use either a 2-inch hitch receiver for hitch-mount platform racks or a strap-and-cradle system with padded straps for trunk-mounted racks.

Ranges depend on carrier type: child trailers commonly accommodate small kid-bike sizes (about 12"–20"); many platform or coupler-style systems reference adult wheel sizes roughly 17"–29" or 20"–29" and list tire widths up to about 5.5" and wheelbases up to about 63"; some child carriers also note compatibility with 26" wheels and larger.

Many trailers fold flat or have collapsible frames and detachable or quick-release wheels for compact storage. Several hitch- and platform-style racks are described as foldable or collapsible to save space when not mounted.

Hitch-mounted platform racks are described for SUVs, trucks, RVs and campers and reference 2-inch hitch receivers. Trunk-mounted racks are shown as compatible with sedans, hatchbacks, SUVs and minivans. Bike trailers attach to bicycles via couplers rather than to vehicle types.
