Resinbike

Resinbike sells hand-built fixed-gear, single-speed and gravel bicycle frames and complete bikes, plus a small line of component upgrades—cranks, wheelsets and resin-inlay handlebars. Prices sit in the mid-range: frames from US $550, completes from US $950 to about US $1,800. Everything is sold direct-to-consumer through resinbike.com; no dealer network or brick-and-mortar stock is maintained. The brand’s calling card is its UV-stable, color-swirl resin artwork cast into CNC-machined frame pockets and bar ends, giving each bike a one-off marbled finish under a clear coat. All frames use 4130 chromoly, TIG-welded in small batches in California, and carry a lifetime warranty against manufacturing defects. The “Marble” fixed-gear platform and limited-drop “Resin Gravel” model are the most referenced collections on cycling forums. Core buyers are urban fixed-gear riders, bike-messenger alumni and gravel commuters who treat bicycles as rolling personal expression. They value US fabrication, artistic customization and Instagram-ready aesthetics over mainstream race heritage, and are comfortable ordering online after selecting from 12 resin colorways and optional component bundles. Resinbike competes with direct-to-consumer alloy/steel singlespeed brands and with boutique small-batch frame builders that emphasize paint or graphics. It differentiates through in-house resin art integration, lifetime warranty on a sub-$2k complete, and rapid color-drop releases that sell out within days, creating collectible demand without the premium pricing of custom builders.
