The Robert Axle has a stainless steel 10x1mm threaded stud to attach the bike hitch. Simply use our Fitment Selector (below link) to find the thru axle designed for your bike. Replace your stock axle with your Robert Axle, install your trailer, and off you go with your kids in tow.
Robert Axles are designed, tested and made in Oregon, USA. They oversee all production and testing and make no compromises in quality or safety when attaching your precious cargo!
Are you struggling to attach the bike trailer to your bike because the axle on the bike has not been adapted for your bike mount? A thru axle adapter from the Robert Axle Project can help. We carry most relevant axle adapters available for bike trailers for kids. The adapters are universal and will also work with other bike trailer brands.
