The seat tube of your bike should leave you a suitable standover gap and usable standover clearance. To get this, find out the top of the seat tube where the seat clamp meets the post. Measure from the middle point of the axle which holds the crank arms together. That number is the length of your seat tube.

To test the standover of your bike, put your leg over the bike’s top tube and straddle it. Take the bike up as far as possible, and have a helper measure the distance between the tires and the ground to ensure that if your bike is the right height for you.

Check Top Tube Length And Reach

To do so, stand up with your back straight against a wall and measure from your knuckles to your collarbone. Then measure from your pubic bone to the hollow at the base of your neck. Now add both results and divide by two. Take that number and add four, this is the perfect length for your top tube.

Loosen the bolt that holds the seat post with a wrench. Swivel your seat post up or down into the accurate position. Once you’re done, tighten the bolt using a wrench. Adjust your seat so that the widest part of the saddle is level with the upper end of the tape measure.

Adjust The Handlebars Of Your Bike

To adjust the handlebar, loosen the bolt at the base of the handlebars using a standard wrench. Lean forward so that your upper back makes a 90-degree angle with your upper arm.
