Bike Builds

All bikes are built, checked and test ridden prior to boxing and shipping. This process averages 1-3 weeks depending on our backlog and the complexity of your build. Expedited builds are available for an additional fee, contact us for details.  

Complete bikes are packed in our own specially designed bike boxes but do require some basic assembly. If you aren't confident in your mechanical abilities please have your local shop do the final assembly.
