Description

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.

Specification

Robert Axle for Kid Trailers replaces your stock thru-axle so you can attach a child or cargo trailer to your 12 mm thru axle equipped bike.

  • This axle is compatible with Burley, Carry Freedom, Chariot/Thule, Croozer, Instep, and many more hitch style trailers.
  • The true length of the axle shaft is 229 mm and comes with a 6mm spacer to make it 223 mm if needed. Please note: Thru-axle lengths do not equal hub standards. An axle has to be longer than the hub to fit in the frame. A 12×197 hub does not equal a 197 mm long axle.
  • This axle has a 1.5 mm thread pitch.
  • The axle shaft and axle end are precision CNC machined.
  • The axle shaft is 7075 aluminum and hard black anodized for rugged durability.
  • The axle end is stainless steel, which allow for mounting of the hitch provided with your trailer. The threads are M10x1 (metric).
  • Hardware for attachment of the hitch is included; the hitch is not.
  • No special tools required. Design allows for installation or wheel removal using your standard 5mm hex wrench.
  • Designed, built and quality tested in the USA. Proven around the world.

    Been using this axle for a couple of weeks now (several rides a weeks, including off-road) and I must say is works perfectly! It fits like a glove on my fatbike and connects the hinge of my Doggyride perfectly on my bike.
    Shipping within a day and delivery within a few days (in the Netherlands).
    Top quality and service (which you don’t get that much these days). Thanks guys!

  2. Steve U (verified owner)

    Purchased for use with a Thule Chariot Lite 2 on my 197 hub fat bike. It shipped very quickly, is very well machined, and hauls the trailer great. Highly recommended!

  3. Rod (verified owner)

    Does what it’s supposed to do – allow me to pull the Burley trailer on my new fat bike!

    Works with no problems, very quick shipping after a fast email response regarding what specific axle to get. Very satisfied.

    Personnel knew their products. Quick turnaround I received the axle in a very timely manner . Been out riding in our Thule chariot and my son thinks the “buggy buggy buggy” is the coolest thing in the world . Ps check out the tee shirt before you complete your order you might want it I did .??

    I have the M2S All Terrain Ultra HT e-bike. I wanted to upgrade the thru axle to support the attachment of a game cart. The stock thru axle on my bike was about 5mm longer than the longest axle offered by Robert Axle Project (229mm). I took a chance and bought the 229mm axle and I was able to get at least 7 threaded turns of the axle into the dropout, which seems to be plenty for safe operation. Now I can easily attach and remove the game cart to my e-bike, which was my goal. Very happy.

  7. Seb C (verified owner)

    Perfect fit on my Rocky blizzard fat bike. Was unsure of the length and someone quickly responded with exactly what I needed. The axle shipped quickly and with the right non-standard spacer for my bike. I’m very happy with it.

  8. Adam D (verified owner)

    I got great help from the staff since I have a brand new bike and the axle is working out perfect!

  9. David Konshak (verified owner)

    I needed an axle to attach to a race wheelchair to be able to pull them in a Fat Bike Race. The axel was perfect and held up just as I needed it to. Thank you

  10. Tuomas Kallio (verified owner)

    Easy to mount, works like charm! Shipping to Europe was supprisingly fast and customer service too.

  11. Justine (verified owner)

    Axle worked perfectly with my fat bike thru axle setup. Their online axle finder found the exact match that would fit my bike. I hooked up a booyah pet trailer to the axle and everything has been smooth sailing. My dogs love going on rides!

  12. Dwight R McCoy

    Easy installation, works as advertised.

  13. Vern W

    Bought the axle for a carbon frame ebike. The axle was built better than I expected. I followed the measuring instructions (helps to have a thread pitch gauge) and the axle showed up and fit perfectly.

    I tow a Burely flatbed trailer to the beach with all my kite surfing gear and this axle is more than up to the task. Nice to know there are still craftsmen out there that care about what they do. Thank you!

  14. Francois L.

    Fit perfectly on my biktrix Jug ultra 1000 for my trailer . Faut delivery, Easy installation.

  17. Jim H. (verified owner)

    Customer service was exceptional. I emailed them to ensure I was ordering the correct axle, and they replied within a few hours. Received the axles in 4 days. Perfect fit, and is very easy to install.

  18. Gary Van Dyke (verified owner)

    I came here based on a Facebook Biktrix Owners Group recommendation. Robert Axel customer service recommended this axel, and it was perfect for my bike. I’m glad I found this site. Shipment was quick and customer service was very prompt and helpful.
