The Robert Axle Project makes thru axles for bikes. Replace your stock axle with a lightweight Lightning Bolt-On Axle or tow your kids with our Kid Trailer Axle. Our products allow cycling families, adventurers, commuters and enthusiasts to enjoy traveling by bicycle without leaving their cargo behind.
With our thru axles, you can lighten up your bike or attach your favorite bike trailer. We have thru axles for Burley Trailers, Thule Trailers, BOB Trailers and more—to any bicycle that has a 12mm thru axle. Find a thru-axle for any mountain, fat, road, cross, and electric bikes.
We understand that there are two priorities for you. Our product must provide a seamless fit between you and your beloved bike and your precious cargo. And it must be durable and secure to bring you home from your adventures, whether around town or around the world. Each axle is specifically engineered and produced to provide a safe and secure connection.
This is a quality axle that works great! We’re very satisfied with it. This company is great with awesome customer service – with my order I asked them to include a drawing of a dinosaur riding a bicycle, and the CEO drew the cutest dino on a bike! I was so excited to open my package and see the drawing!
I recently purchased an axle for my BOB trailer and couldn’t be happier. From the axle finder tool through to the fast processing and shipment of my order, and even the installation how-to video, everything with the process was smooth and easy. The axle fits perfectly and installation was a snap. I would (and will) wholeheartedly recommend the Robert Axle Project to anyone looking for a thru-axle trailer mount.
This axel worked great so I can now pull my twins in our chariot on my mountain bike. Easy instructions, great website. Thanks!

Planning a mini-bike tour is a little like planning dinner – you want it to be great, but you also don’t want to stress out and worry too much about it. Often times, like a good meal, you can pull something together in a fairly short amount of time, with little effort. And like anything, […]
