Sizing
How to Measure Your Inseam for the Perfect Bike Fit
To get the right size bike, start with measuring your inseam. This is crucial for ensuring your bike is comfortable and easy to ride. Follow these steps:
- Stand Straight: Stand with your feet about 6-8 inches apart on a flat surface.
- Measure Your Inseam: Use a tape measure or a fabric measuring tape. Measure from the ground up to the top of the inside of your leg, right at the crotch.
- Check the Bike’s Standover Height: When you compare your inseam measurement to the bike's standover height (the distance from the ground to the top tube), make sure there’s at least an inch of clearance between your body and the top tube when you stand over the bike.
