At Factory Five, custom builds were our bread and butter for a very long time. We know every inch of a bike and how to consider every aspect to achieve something unique, beautiful and functional for the right riding needs.

We took a step back from custom frame and bike design, but will still work on the occasional project. To see our past work you can have a browse through our portfolio.

We assemble every build from our workshop in Shanghai China. This way we can control every step of the build and ensure it is to our standards. We treat every bike like it is one of our own.


Our frames come in our signature colors and are available to be built up to your choosing. Select from the hundreds of parts and components we offer to create exactly the type of build you like.

Looking for something for commuting prowess, cruising comfort or superlight racing? We can help you choose the right combination of frame, wheels, bars and everything else to achieve the right mix of function and style.


Our frame painter has decades of experience with frame coating. We use the pantone system and can paint any of our frames with virtually any color. Pricing for custom finishes starts at only ¥250 (US $35) for a block color and increases from there to include:

» Metallic and sparkle finishes » Two-color fades
» Raw, brushed and flame treatments » Custom decals
» Matte, satin and clear topcoats » Application of existing decals
» Partial or full chroming of tubes



We can accommodate completely custom frame sets. We design fully custom geometry using any of our tubing sets including the entire Columbus range. If you need something very special and exactly to your choosing then a custom frame allows complete control.

» Flat or smoothweld joints » Custom geometry
» Lugged or fillet brazed steel » Headset and fork specification
» Custom dropouts » Braze ons and internal gear routing
