What's New in Bike Builder

1.4.0

July 21, 2026

Three new ways to choose, compare, and start — plus a new check and two fixes. • Help Me Choose — a guided flow. Tell it how you ride and a couple of body measurements, and it ranks frames that actually fit your geometry — and shows you why each one made the list (stack, reach, the math). It's a starting point, not a verdict: the fit estimate is from your height, so confirm with a fitter before you buy. No brand pays to rank higher — everything's judged on the same axes. • Complete Bikes — browse 70+ real, manufacturer-spec'd complete bikes (road, gravel, all-road — no MTB), compare them against your own custom builds, and see "buy it complete vs. build it yourself" pricing on one screen. Every single bike opens straight into an editable build — swap one part or all of them, and the compatibility engine keeps checking as you go. • Compare 2.0 — line up to six builds side by side with photos, total weight, total price, and full geometry. The best number in each row is highlighted, the gap to it is spelled out, and weight + cost are charted so the trade-offs jump out. • New check: cassette vs. derailleur range. You'll get a heads-up when a cassette's large cog is outside what your rear derailleur is rated to handle — that's 28 compatibility checks now running behind the scenes. • Fixed: brands now sort A–Z no matter how they capitalize their name (sorry, evolve — you're back where you belong). And "Buy" buttons that were missing for several direct-to-consumer brands now route correctly to the retailer's product page. • As always: when we can't verify a number, we show the gap instead of inventing one. 700+ parts across 100+ brands, updated weekly without app updates.

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
