What's New in Bike Builder

1.4.1

August 12, 2026

• New: rate Bike Builder right from Settings — we'd love to hear what you think! • More reliable catalog updates: a single bad part entry can no longer block the whole catalog from refreshing. • Wheelset rim depths now support fractional manufacturer specs (like 54.5mm) for exact-spec accuracy. • Under-the-hood hardening across the wheelset catalog.

Limited selection, shilling for affiliates

This is basically just an app of affiliate links with very limited selection, not particularly helpful.

Response from developer

Thanks for the honest read — you're right that we're not there yet. Bike Builder is half-built. Catalogue depth is going to keep getting deeper (bottom brackets are missing — a real gap that came up during my brother's build this week). And you're right that the build experience needs to come first, not the buy button. Working on both. Also coming: a "help me pick" frame finder, a build sheet you can hand your local bike shop, a web version, and a lot more brands. Free while we build. Stick with us if you can. Feedback goes straight to me. — Regan, founder
