Seat Tube Length
The seat tube height should be adjusted as such that while pedaling your leg should not be fully extended at the bottom of the pedal, and your leg should not push against your body on the upswing.

Effective Top Tube Length
The effective top tube length impacts your reach, if the top tube length is too long your body will be stretched and that may cause back pain and if the length is too short you may find it difficult to handle the bicycle. Our products feature an adjustable handlebar stem which lets the rider do the ergonomic fine-tuning.

Standover Height
For a comfortable experience, there must always be at least an inch or so space between you and the top tube on your bike when you are standing flat-footed. You can measure your inseam length and check that value against the table provided below.
