This site makes it easy to:
Anyone can add a bike.
Launched in January 2017, it has quickly become the world's biggest open-access bike geometry resource.
In July 2017 we added the world's most complete database of bike fitters.
In January 2019 we hit a record 30,000 unique users visiting the site, from all over the world. Still growing.

It's a spare-time project by two guys. Got feedback or ideas? Let us know here.
A bike's geometry strongly influences its handling, your comfort, your aerodynamics and your power output.
Fit can have far more impact on performance and feel than expensive components.
You probably want to compare potential new bikes and your existing bike(s) before you buy.
Finding the right geometry chart for an older or second hand bike can be hard. It usually involves lots of Google image searches and not being entirely sure you've found the right model year.
When you do eventually find it, the information is never laid out the same way between brands. It's tricky to compare more than a couple of aspects without writing it all down.
Yes, there are bigger problems in the world, but we'll fix this one.
Bob is good with bikes, and dabbles in code.
He loves everything on two wheels, and rides mountain, road and track. He once ran a business refurbishing second hand bikes, but has now returned to 'proper' work.
Dave is good with code, and dabbles in bikes.
He's an experienced product and marketing manager for tech companies.
