How to use

Some bags attach directly to a bike's frame, while others require a rack mounted over one of the wheels.

Different ways to haul gear on your bike

• Bike cargo rack: A stable frame mounted over one of the wheels; you can strap gear directly onto the rack or use bags designed to attach to them, such as panniers
• Panniers: Roomy bags popular among commuters; they're easy to detach from the bike rack so you can take your gear with you
• Frame bag: Fits in the main triangle of your bike frame; ideal for carrying smaller, heavier items
• Trunk bag: Secures to a bike rack; many have plastic sheets to reinforce the base area and retain a structured shape
• Handlebar bag: Keeps gear within easy reach; attaches to handlebars with straps or clamps
• Saddle pack: Fits under the bike seat for small items like a multi-tool or patch kit; larger versions designed for bikepacking carry more
• Bike basket: Great for taller or odd-shaped items like grocery bags since baskets don't have lids; front baskets attach to handlebars
• Bike trailer for cargo: Keeps weight off the bike frame and you lets pull heavier loads behind you
