The fixed gear adapter is a custom solution to convert your Wahoo Kickr smart trainer into the ultimate track bike erg.
This updated design includes a through axle, and makes changing between the trainer a your track setup a lot quicker and easier.
The adapter replaces the freehub with a fully locked fixed gear hub to fully replicate the track bike experience indoors. A special Track bike specific through axle replicated the rear wheel of the bike making it an easy swap over between indoor training and riding on the track.

Well made and quality piece. It was rad to install.
I first started training indoors on a fixed gear bicycle which I already owned and a "wheel on trainer." After shopping around for a used bike to use on a direct drive I found the Velobike adapter and decided to try it. DD trainers are way better in everyway and free of tires, tubes, and maintenance. Thanks for helping provide me a better indoor experience. I am ooking forward to trying some of the other innovative products Velobike offers.
The quality of the adapter and the parts used is very high. It fits perfectly with the Wahoo Kickr Core trainer. The little extras and the quality of packaging design are wonderful. Customer service is very good and shipping is super fast. It's great to see people so passionate about their work and products.
Glenn was super helpful in identifying what KIKR I had and making sure I purchased the right adaptor. Glenn also has a really good youtube video on how to install the adaptor that is easy to follow.
The adaptor works like a charm. My track bike is now a smart trainer. I can now do all my interval workouts on my track bike with exactly the same crank length and position. I use trainerroad and I often create workouts using garmin connect. So the adaptor has been a huge help.
I only have to remember to calibrate the trainer's power before I get on the bike. That's because there is no longer a freewheel to allow the trainer to spin down during calibration. So I use my arm and just let the pedal go when the trainer is at the required speed..
