Determining the right bicycle size is easy.

Inseam x .65 = Iride size
regular sizes

Inseam measurement may be different from pants size.
Take measurement from floor up to your good stuff.
Remember:  inch x 2.54 = cm
Consider the shoes and pants you will be wearing while riding, shoe thickness will affect this measurement; you want clearance over the bike’s top tube so that you can stand flat footed while waiting for a light.

Inseam inch x 2.54 x .65 = Iride size

Round down; if unsure, go with a very slightly smaller frame size.
If the frame is too large, you’re stuck. If the frame is too small, you can get a longer seat post or stem. Finding a good size is pretty easy.
