Child and cargo bike trailers add carrying capacity without loading the bike's rear rack. Choose a single- or double-child trailer for family rides, a cargo trailer for shopping and touring equipment, or a versatile model that converts for strolling or other approved activities.
Why Choose a Bike Trailer?
A trailer can provide an enclosed passenger space with weather protection, ventilation and room for essentials, while cargo models carry larger or more awkward loads behind the bike. Many trailers fold for storage and transport, and selected child models accept approved conversion kits for use away from the bike. The separate load can also suit bikes that do not have a compatible pannier rack.
What to Look for in Child & Cargo Trailers
- Passenger or load capacity: Check the stated number of children, age and developmental guidance, individual and total weight limits, cargo space and permitted use.
- Bike and axle compatibility: Identify whether the bike uses a quick-release skewer, solid axle or thru-axle, then confirm the required hitch, adapter or replacement axle.
- Journey and storage needs: Compare weather protection, ventilation, suspension, wheel and tyre design, folded dimensions and any approved strolling or jogging conversion kits.
A trailer described as universal may still need bike-specific fitting parts. Hooded dropouts, hub gears, hub motors and thru-axles can require a spacer, adapter or replacement axle, so match the exact measurements rather than choosing by appearance. Follow the trailer instructions for harnesses, safety straps, flags, visibility and load distribution.
