HOW TO MEASURE YOUR INSEAM:

The MOST IMPORTANT measurement when sizing a bike is your inseam length. Don't base your inseam simply on your jean size. The more precise, the better.

1. Stand with your back against a wall and spread your feet 6"- 8" apart.
 
2. Place a book between your legs and up against the wall, spine up; raise it until snug against your crotch (this mimics your bike seat).
 
3. Have another person measure from the top of the book (spine) down to the floor.

Expert Opinions on Our Diamond Frame Bikes

"The bike itself has a vintage style that we really dig, but it's all the extra effort Brooklyn Bicycle Co. goes to for customers that permanently raises the bar."

"This double top-tube bicycle is a classic design with an added second horizontal support that increases the strength of the frame.”

Bicycling

"I found a reliable site to buy a bicycle online — my hesitations over quality are gone after putting my bike through its paces on the pothole-riddled streets of NYC."
