Robert Axle Project Kid Trailer Thru Axle

This axle is designed for bikes with 12mm thru-axles. You must verify your bike's specific thread pitch and length requirements, as thru-axle standards vary significantly between manufacturers. We recommend using the Robert Axle Project's online fit finder tool to confirm compatibility before purchasing.

No, this product includes the axle and the necessary hardware to attach your hitch, but it does not include the trailer hitch itself. You will need to use the hitch that came with your specific trailer.

It is designed to work with any standard hitch-mounted trailer, including child, pet, and cargo trailers. As long as your trailer uses a standard hitch attachment, this axle provides the necessary mounting point.

Installation is straightforward and only requires a standard 5mm hex wrench. You can easily swap it out with your stock axle whenever you need to attach or detach your trailer.

Yes, you can leave it installed permanently. It functions exactly like your stock thru-axle, so there is no need to remove it unless you prefer to switch back to your original axle for aesthetic or weight reasons.
