Bicycle research, made useful
Find the right bike. Compare what matters.
Search published bicycle records, narrow your choices with rider-fit and geometry tools, and compare selected sizes, gearing, specifications and service evidence—with missing data shown honestly.
Choose with confidence
Three ways to narrow the decision.
Bike Finder
Answer a few simple questions about your measurements, riding style and budget to find real Archive bikes in specific published sizes.
Find bikes for me Select 2 or 3 BikesCompare Bicycles
Choose bikes from Archive results, select one published size for each, and see meaningful differences in fit, handling, gearing, equipment and service evidence.
Choose bikes to compareFit & Geometry
Record transferable fit coordinates, inspect a published frame at one shared scale, and understand how reach, stack and handling geometry differ.
Why Velopedia
Useful facts, clear limits.
Published bicycle records
Research original specifications, published geometry and historical model details. When evidence is incomplete, the record says so.
Transparent comparison
Rules compare selected-size geometry, gearing, specifications and service evidence. Missing or incompatible data never appears equal.
Useful after purchase
Use inspection guidance, replacement-part evidence and workshop tools, then keep a private record of setup, service and upgrades if you choose.
Workshop Tools
Build, set up and service the bike.
