How does in-home assembly work?

When you are purchasing your bike, you will have an option for in-home assembly. Once your bike has been purchased, our team will reach out to a local professional Keiser installer to schedule assembly. Installation of your new bike will be scheduled for the day of, or just after delivery.

We know that during the current pandemic having someone come into your home isn't the best solution. All of our Keiser installers take all necessary precautions inline with the recommended CDC guidelines. If having an installer come into your home is still not an option, we can arrange for the installer to assemble your new bike in your garage or outdoor space.
