Robert Axles for Kid Trailers are designed specifically to fit your 12mm thru-axle bike and allow attachment of any hitch-mounted trailer. These fit any trailer that has two wheels and a single point of attachment to the axle. This includes all the two-wheeled child, pet and cargo trailers such as: Thule, Chariot, Burley, Instep, Carry Freedom, and many more.
This axle is compatible with bikes that have the NAILD thru axle system and 12×148 Boost hub spacing.
Since 2013, we have been an important part of cyclists’ adventures all over the world. Our axles have millions of miles on them in mountain bikes and road bikes, carbon bikes, fat bikes and e-bikes. Our axles are specifically designed to handle the high-torque loads generated by e-bikes.
Your stock thru-axle is not strong enough to haul your precious cargo! Our axles are 3 to 4 times stronger than the stock axle that came with your bike. Our stainless steel axle ends provide a safe and secure attachment point of the hitch to the axle. The axle is quick to install and remove with a common 5mm hex key.
Our axles are not just designed in the USA, but are made here as well. They are machined by avid cyclists to the tightest standards in the industry. We safety test, to failure, every batch of axles we produce to ensure they exceed your expectations.
Please note: In addition to our 12mm Kid Trailer Axle required to attach the trailer to your bike, we encourage you to consider replacing your stock axle with our Lighting Bolt-on Axle, which replaces your NAILD thru axle system with a simpler, lower profile and easier to use thru axle when you aren’t using your trailer. With purchase of both our Kid Trailer Axle and Lighting Bolt-on Axle you can quickly switch back and forth between axles using the hex wrenches commonly found on your multi-tool.
Robert Axle for Kid Trailers replaces your stock axle to attach your child trailer to your 12mm thru-axle equipped bike.
